Safe Inspection Procedures and Practice (4)

Specific Inspection Hazards (4)

DO NOT OPERATE ANY VALVES/FITTINGS OR ENTER ANY TANK CONTAINER WHICH DOES NOTPOSSESS A VALID SAFETY DOCUMENT.

SEE SECTION 2 FOR DEFINITION OF A VALID SAFETY DOCUMENT.

INTRODUCTION

Inspections and works should be carried out in compliance with international, regional and local laws including

health and safety regulations and regulations appertaining to working in confined spaces, fire and explosions.The following is for guidance only.

SAFE INSPECTION PROCEDURES AND PRACTICE

Tank containers are designed to transport cargoes which may be dangerous. Characteristics and safetyhazards associated with specific cargoes are available from the manufacturers Material Safety Data Sheet(MSDS).

Cargoes might be transported under a blanket layer of inert gas such as nitrogen. An inert gas cannot supporthuman life; breathing any gas mixture possessing less than 19.5% of oxygen is likely to cause suffocation(asphyxiation). Prior to a thorough cleaning and ventilation, tank containers may not possess adequate oxygento sustain life or may contain harmful or explosive vapours hazardous to one's health.

Do not operate any valves/fittings or enter any tank container which does not possess a valid safety document.Comply with the MSDS.

Personnel must not enter any tank container until a tank container entry permit has been completed. Entry permits are designed to help ensure compliance with confined space entry laws and regulations of allgovernments having jurisdiction (nation, state/province, locality, etc).

Before entering a tank container the inspector must:

− Check the last cargo and safety data (MSDS) and take appropriate action.

− Check that the container has been cleaned and cleaning document issued.

− Check that the container has been adequately ventilated with fresh air to ensure a minimum oxygen content

of 19.5%.− Check the container atmosphere to determine the absence of explosive or flammable vapour or gas.

− Check that an attendant who has full knowledge of the time of entry is stationed outside the container in theimmediate vicinity and that the inspector and attendant are equipped with all safety and rescue equipment required by all applicable laws and regulations.

SPECIFIC INSPECTION HAZARDS

Personnel must be mindful of certain specific hazards which could potentially arise when inspections or testing

of tank containers are performed. These include but are not limited to:− Asphyxiat ion or poison ing upon entry into an unclean container or a container possessing insufficient

oxygen.

− Sudden release of pressure from discharge valves or manlid if opened while container is under pressure. Avoid standing in front of fittings, openings or over the manlid if the possibility of sudden pressure dischargeexists. Personnel should depressurise the container vessel by carefully operating the airline valve. Do notdepressurise the container vessel by attempting to open the manlid.

− Always face away from the manlid opening when final ly crack ing and li ft ing the manlid to avo idinhalation of any potentially hazardous escaping fumes or unanticipated pressure release. Ensurethe body is not in direct line with the valve opening.

− Sudden release of steam or test pressure from steam tubes. Avoid standing in front of steam tubeopenings or quick release valves if the possibility of sudden pressure discharge exists, or when

depressurising the steam heating system. Do not rely upon steam dust caps to hold pressure.− Jamming of fingers in open valves during inspection. Do not place fingers into open valves as sudden

closure could crush fingers.

− Falling from damaged ladder or walkway. Ensure repairs to damaged sections of ladder or walkway priorto treading on them if condition is unsafe to proceed. Ensure that there is no contamination on the ladder,walkway or footwear which may cause loss of grip. Access the top of the tank via a gantry.

NOTE: ALL PERSONNEL HAVE A RESPONSIBILITY FOR THEIR OWN HEALTH AND SAFETY AND MUSTTAKE CARE TO REDUCE ANY RISKS TO AN ABSOLUTE MINIMUM.

DEFINITIONS

The following definitions are used in this manual:

1 Damage

Damage is one or more physical defects in a container caused by a single event or a series of events such asimpact, abrasion contamination, cargo attack, etc which exceeds the acceptable limits as defined in Section 8entitled Inspection Guidelines for Tank Containers of this handbook. This includes corrosion, pitting or gougesto the interior or exterior of the container, shell, fittings or accessories.

2 Wear and Tear

Wear and tear also referred to as Age Related Deterioration (ARD) is one or more physical defects resultinginevitably from exposure of the container to conditions for which it was designed. It precludes the existence ofany physical defect which is considered unacceptable in accordance with Seaco's Inspection Guidelines forTank Containers, as defined in Section 8 of this handbook and which may have led to the deteriorated condition. Any deterioration resulting from improper use, improper maintenance or lack of maintenance is not fair wear andtear.

3 Improper Repairs

An improper repair is any repair performed where any one of the following defects is present:

− The repair has not been performed in strict accordance with Seaco guidelines

− The repair is of a quality or condition which could still be defined as damage according to Seaco guidelines

− The repair has an adverse affect on the original ISO dimensions of the container

− The repair affects the structural integrity of the container

− Use of incorrect materials

− Sub standard preparation or painting− Poor quality welding or workmanship

− Sub-standard cleaning or polishing of the tank container or fittings

4 Full Refurb ishment

Full refurbishment is the process of removing all the paint coating and any corrosion from the container frame byabrasive blasting followed by repainting and replacing the cladding and insulation.

The insulation and cladding may be refurbished as part of a full refurbishment process. However, it is notessential for the cladding to be included in a full refurbishment process.

5 Partial Refurb ishment

Partial refurbishment is the process of renovating areas of the container to an extent less than that defined asFull Refurbishment.

6 Re-manufacture

Re-manufacture is the process of removing the frame and insulation and re-using the original tank shellin a new frame and new insulation.

7 Tank

Tank Container in its entirety (Not just the tank shell)

8 U.N. Portable Tank

Tank container designed and approved for the carriage of dangerous goods (as defined by U.N. DangerousGoods List).

COMPLETION OF TANK CONTAINER REPAIR ESTIMATE

The following instructions are for the benefit of depots that prepare manual repair estimates (RE).

Introduction

A repair estimate (RE) (which performs the function of off-hire damage report) must be completed by the depotfor every tank container entering the depot off lease or unavailable condition.

Freemove units moved in status ‘AVLB’ condition or new units ex manufacturer must be checked to ensure theyhave not suffered transit damage. If such units have transit damage then a repair estimate must be completedfor that unit.

Listed below are descriptions of the entries that must be made in each section.

* Depots should , if possible, report the repair estimate via EDI using their depot management system.

1. Last Cargo

Enter the proper shipping name and U.N. number of the last cargo carried.

Note: Abbreviations o f the cargo name, brand name or propr ietary name are not acceptable.

The depot must be in receipt of a safety document stating the proper name of the last cargo, together with theU.N. reference number, prior to carrying out the inspection. Additionally, information concerning last cargo will have already been advised in writing by the local SeacoOperations Centre prior to redelivery.

It is vital, both for the safety of personnel and in order to convey last cargo data to the next user of the tankcontainer, that the last cargo data is accurate in every detail.

If the information is missing or incomplete for any reason, the depot must contact the last lessee or SeacoCustomer Service Centre.

Do not enter incorrect or incomplete information.

2. Test Date

This refers to the last 2.5/5 year statutory pressure test. Enter date of last test shown on the tank container dataplate.

Note: Refer to Section 8.13c to determine when the statutory testing must be performed.

3. Container Grading

Unlike other SEGU equipment types there are no grading procedures applicable for tank containers.

4. Component

If estimating with the ISO coding system use the 3 digit alpha codes to denote the component.

Enter the 3 digit alpha code shown on the component list for any item which is damaged.

Appendix 3.3 shows a list of tank container components.

5. Damage Codes

Use the 2 digit alpha codes ISO coding system to denote the damage.

Only note damages that exceed the acceptable limits, as defined in Section 8 (Inspection Guidelines for TankContainers)

See Appendix 3.4 for the full description of all damages codes applicable to tank containers.

Depending upon the location submitting the estimate the damage code used to describe any particular damagemay automatically allocate the costs of the repair. Therefore, the damage code system has important

operational as well as technical implications.

Where automatic cost allocation does not take place then the depot will assign the damage responsibility.




Page | 17

Notes on the use of damage codes:

(i) Damage codes must always be used as a single code. A combination of two or more codes to describedamage to any individual item is not permitted.

(ii) Improper Repairs (Codes IO & IR)

There are two possible codes which can be used:

IO: Improper Repair - Old

IR: Improper Repair - New

The inspector must decide by reference to the on-hire date whether the improper repair was carried outduring the most recent lease (Code IR), or before it (Code IO).

(iii) Damage caused by Rust(Code CO)

Code (CO) must be used only in clearly defined circumstances as follows:

(a) It must be used as a single code in any line of the repair estimate to describe damage caused by rustwhich is not a result of a manufacturer's defect or cargo attack or contamination. The nature of the damagewill be sufficiently implied in the appropriate repair code(s) which are entered in the adjoining column. (b) It must be used in any line of the repair estimate to describe rust, as defined in (a) above, whichrequires rectification, by partial refurbishment.

(c) In the case of a full refurbishment of a tank container damage code CO can only be used for tankcontainers which are more than 5 years old or which are subject to a refurbishment Tank Technical Bulletin(TTB).

For tank containers less than 5 years old use damage code MN (New Manufacturing Defect) or CD

(Consequential Damage).

(iv) Consequential Damage – (Code CD)

Must be used for any damage resulting from the Lessee's failure to carry out a necessary repair. See Appendix 3.4 below for a full description of the use of damage code CD.

(v) Manufacturers' Defects(Codes ME and MN)

There are two possible codes which can be used:

ME: Manufacturers' Defect - ExistingMN: Manufacturers' Defect - New

(a) Code ME must be used to describe damage caused by a manufacturers' defect which is subject to a TTB.The TTB identifies the series of tank containers affected and gives instructions on repair method andreporting procedure.

(b) Code MN must be entered to describe 'new' defects i.e. not yet identified by TTB.

See Section 5 regarding the procedure for reporting both existing and new manufacturers' defects.




Page | 18

(vi) Allocation of Costs

The allocation of repair costs between the two principal account categories, Lessee and Seaco, is determined bythe damage code or by the depot assigning responsibility, depending upon how the depot is set-up.

Appendix 3.4 shows the damage codes which must be used in each of the circumstances defined.

The first heading entitled ANY ITEM covers all components of the tank container.

6. Repair Codes

ISO Codes

See Appendix 3.5 for the full list of repair codes.7. Damage/Dimensions - Remarks

Specify the quantity and extent of repair requirement against each damaged component.The type of damage and repair method proposed should have already been noted in the damage and repaircodes. Therefore, no description of the damage and repair methods is required except in the case of damagesor repair methods that cannot be adequately described by use of the coding system.Note: - All dimentions to be metric.

Appendix 3.2: ISO Damage Locat ion Code System

Tank container components have their location identified by alpha codes (up to 4 characters in length).

Appendix 3.3 below notes the components by section. The location code for each component is notedalongside the component. Only location codes noted alongside the component may be used.

Damages will be located by panel(s). For the purpose of locating damages, the tank container is dividednominally into 4ft x 4ft (120cm x 120cm) segments.

A tank container frame locat ion code consists of four characters depending upon the area contain ingthe entire vertical and horizontal length of the damage.

Location Code 1

1. The first character is selected to identify the appropriate face of the tank container as follows:

• R Right Side• L Left Side

• T Top

• B Bottom (Floor)

• F Front End

• D Ladder & Data Plate End

• U Understructure

• X Whole Container

• I Container Interior

• E

Container Exterior

Location Code 2

2. The second character is selected to identify the appropriate part of the tank container face where thedamage is contained. To do this the vertical faces of the tank container are divided into the top and bottomhalves and upper and lower main components; the horizontal faces of the tank container (roof or top andfloor or bottom and understructure) are divided into right and left halves when viewed from the rear end.

The relevant codes are:

• H Upper (Higher) Component

• T Top Half

• B Bottom (Lower) Component

• G Lower Component (Ground)

• L Left Half

• R Right Half

• X Both Halves (i.e. Top/Bottom,Left/Right, Centre)




Page | 23

Location Code 3

3. The third and fourth characters are selected to identify the section of the tank container in which the damageis contained.

a) On all containers the front and rear ends are divided into the vertical section numbered, when viewedfrom the rear end from left to right.

1 - For the left hand side corner post2 - for the left half3 - for the right half4 - for the right hand side corner post

b) On all containers the right and left sides, the roof, the floor and the understructure are divided into equalsections as follows: 5 sections - 1 through 5

c) When the damage covers one section only, the third character indicates the appropriate section number

and the fourth character shall be filled in with ‘N’.

d) When the damage covers several adjacent sections the first and last section shall be employed.

e) When the damage covers several non-adjacent sections or if the damage/ repair details are not thesame, then separate line items must be used.

f) When the damage covers the entire length of the container face, the third and fourth characters are filledin with ‘X’.

Location Code 4

4. Numbering system for multiple components.

a) In addition to the above described location code some components are more precisely identified innumerical order.

b) The particular components of the rear and front end are numbered consecutively from left to right whenviewed from the rear end.

c) The particular components contained in all other faces such as side posts, crossmembers arenumbered consecutively from the rear end.

d) When the damage covers several faces of the inside of the container such as steam cleaning, polishingthe code IXXX shall be used.

e) When the damage covers several faces of the outside of the container such as refurbishment, refixing orsealing cladding panels removal of cargo stickers the code EXXX shall be used.

INSPECTION PROCEDURES

Introduction

There are seven standard inspections that might be carried out while tank containers are in depot off-hire.Seaco will confirm the inspections required.

All inspections must be carried out by a Seaco Surveyor except for pre-delivery on-hire surveys which should becarried out by the depot's own quality control personnel.

Inspection Types and their Objectives

A. Pre Repair (Est imate Veri ficat ion):

Ensures the repair estimate conforms to Seaco requirements prior to transmittion to Seaco OperationsCentre

B. Joint-Survey: Confirms with the customer's surveyor the allocation of repair costs

C. Post Repair: Ensures the tank container has been repaired correctly and is status ‘AVLB’

D. Combined – Post Repair and On-Hire: Ensures the tank container has been repaired correctly and is status ‘AVLB’ (Additionally, provide forinspection as in F).

E. Supplementary Estimate Verifi cation: Ensures the additional work is necessary

F. On-Hire Survey: Performed prior to lease, ensuring the tank container complies with requirements. The report is posted onsurvey company web site and includes itemised report, photos and cleaning certificate

G. Pre-Delivery Inspection: Depot check prior to lease ensuring the tank container complies with requirements.




Page | 44

A. Pre Repair (Est imate Ver if ication)

Authent icating the Repai r Es timate

This must be performed promptly after depot has completed the repair estimate.Must be performed as requested by Seaco Operations.Is not required on tank containers freemoved from manufacturer unless specified by Seaco Operations.

Note: These tank containers will require a visual exterior inspection for transit damage after freemove.

Action to be taken by the Seaco Surveyor: The Seaco Surveyor must inspect the tank container and ensure that the repair estimate is correct. The repairestimate must be completed in accordance with the instructions in Section 3. When the Seaco Surveyor issatisfied that the repair estimate for the tank container is correct he and depot representative must sign anddate the estimate.

Repair estimate checks must inc lude:

− A current, valid cleanliness certificate

− The last cargo data is correctly entered

− Damage codes entered correctly

− Only damage requiring repair is noted

− Correct method of repair is adopted

− Tank Technical Bulletin requirements met

− Repair costs (labour/materials) are correct to tariff and use the most cost effective repair method andreduced costs for combination damages

− Function testing of the electrical heating or other components has been carried out

− Statutory test requirements complied with

− An internal mapping chart completed if a problem exists on the shell interior

B. Joint Surveys (with customer’s surveyor)

The joint survey is carried out after the post-estimate inspection and must be performed using the SeacoDamage Notification.

The customer's surveyor must provide their own copy of the damage notification. All customers’ surveyors mustattend at same time.

The two surveyors must agree the material costs and labour hours as allocated or an amended allocation. Theestimate must clearly show all amendments.

The estimate must be signed and dated by both the Seaco and customer's surveyors.

The Seaco Surveyor may alter an item on the estimate by amending the damage and repair codes, descriptionand the costs.

After amendment the repair must still conform to tank inspection criteria or requirements.

All amendments must be agreed with depot.

If the customer's surveyor agrees costs, but refuses to sign the estimate, he should be warned that thesurvey is invalidated. The Seaco Surveyor must write on the estimate Costs agreed but customer'ssurveyor unwilling to sign, and sign/date it himself.

The depot must report the joint survey result and amended costs immediately to the local Seaco OperationsCentre via the reporting system.

If agreement is not reached between the surveyors then the Seaco Surveyor must immediately report to thelocal Seaco Operations Centre.

Lessee Refused Costs Report

− Details of refused costs

− Colour photos of the refused items

− Reasons why costs refused

− Send report to local Seaco Operations Centre

− A copy of this form is shown at Appendix 4.1

C. Post Repair

The post repair process is used as a means for Seaco to verify that the unit has been repaired in accordancewith the estimate and meets all applicable criteria for a unit to be on-hired.

The post repair inspection procedures will be performed in depots as requested by Seaco Operations.

Post Repair Inspection

The following procedures must be followed when performing a post repair inspection.

At any time new or amended requirements or criteria may be introduced for specific tank containers or tankcontainers in general, these must be applied in addition to the procedures below during the post repairinspection.

C.1. Tank Container

The tank container being inspected must meet the specifications of a status ‘AVLB’ tank container with regard tothe inspection criteria as noted in the Tank Inspection Handbook, TTB’s and other technical requirements thatmay be in force. All repairs noted on the estimate and any damages that were not noted on the estimate mustbe fully repaired.

Additionally an internal mapping chart will be completed and photos taken of the various components noted

below in C.3.

C.2. Statutory Test Validit y

The inspector must ensure that the tank container statutory test validity is current; otherwise it must be updatedas necessary. The requirements of the statutory test are noted in the Tank Inspection Handbook.

C.3. Photos and On-Hire Report Check

Every tank container will require a number of photos to be taken during the on-hire inspection. The photos mustclearly show:1) External full side RHS / LHS view.2) External full rear end / front end/top/underside view.3) External rear/side 45 deg.

4) External front/side 45 deg.5) View of rear top compartment, containing fittings in close-up when lid open.6) View of top centre compartment containing fittings in close-up when lid open.7) View of rear bottom compartment containing fittings in close-up.8) View of all other fittings,9) Views inside vessel showing all apertures and fittings.10) Internal RHS/LHS view.11) Internal rear end / front end/top/ bottom view.

11) Data plate

An on-hire report must be completed in an approved format together with an internal mapping chart. Thecleanliness certificate shall be renewed. The report and photos must be made available on the inspectioncompany’s web site.

C.4. Cleanliness Certificate

Every tank container must enter the depot with a valid cleaning document. At the conclusion of the on-hireinspection the inspector should re-validate the existing cleanliness certificate or issue a new certificate.




Page | 46

C.5. “ T” Code Verification

Type Code Veryfication:

Check that the tank conforms to the material type code as stated on the return reference, i.e. T11A25. Ifthere is a discrepancy inform Seaco Operations Centre.

See below tables for descriptions:

The last 2 numbers refer to the capacity of the tank in 1000 Litres. I.e. 25 = 25000Ltrs.

Notes: Post Repair

Note 1

If the Seaco Surveyor considers that the depot has omitted to repair items included on the estimate or has notrepaired items correctly, then the surveyor must clearly mark these items for rework on the estimate and re-workreport

The cost of rework is for the depot’s account.

Rework repairs must commence immediately and be completed in a timescale agreed with the Seaco surveyor.

Following completion of rework, the tank container must be re-inspected by the Seaco surveyor. Inspections will

continue until the Seaco surveyor is satisfied that it meets the Seaco requirements and quality standards.

Note 2If the Seaco surveyor considers that additional repairs are required, the depot must produce an additionalestimate which must be approved by the Seaco Operations Centre.

If the additional repairs are required as a result of damage caused to the tank container whilst in the depot orrepairs that should have been identified by the depot estimator at the time of off-hire, the costs of rectificationmust be for the depot account. In this case no additional estimate is required.

D. Combined Post Repair and On-Hire

This inspection combines the inspection requirements of

C. Post Repair and F. On-Hire Survey




Page | 47

E. Supplementary Estimate Verification

The original estimate should indicate all damages requiring repair in addition to all TTB’s and maintenance work

required at the time of redelivery.

Normally the only time a supplementary estimate for extra work will be required is when a tank container hasbeen in depot for a period of time and it requires maintenance work or when there is a specific request from thelocal Seaco Operations Centre to modify the tank container or fittings.

Any supplementary estimate should be submitted as per all normal procedures. The local Seaco OperationsCentre may request a survey prior to work being authorised. Photographs to be supplied if necessary.

The survey must ensure that the work is actually necessary and that it conforms to Seaco requirements and toallocate the costs to either the depot or Seaco account.

F. On-Hire SurveyIf the customer requests an on-hire survey the procedures below must be followed in addition to the pre-delivery inspection procedures.

If the customer does not require an on-hire survey then the pre-delivery inspection carried out by the Seacosurveyor will serve to ensure that the tank container is in good working order prior to delivery to lease.

Procedure

This survey must be carried out with reference to the criteria detailed in Section 8 (Inspection Guidelines forTank Containers).

If an item is beyond the acceptable limits as specified in Section 8 the survey must cease until the requiredrepairs have been carried out.

If the customer's surveyor accepts the tank container as being in satisfactory operating condition butnevertheless refuses to sign the on-hire survey form, the Seaco representative must note in the REMARKS boxthe words ‘acceptable to customer but customer's surveyor unwilling to sign’. The Seaco representativemust also add brief comments as to the reason for the refusal. The Seaco representative must immediatelyadvise the local Seaco Operations Centre.

The Seaco surveyor must immediately inform the local Seaco Operations Centre:

− Customer’s surveyor rejects a unit as non- satisfactory and in the opinion of the Seaco surveyor the tankcontainer is in satisfactory condition.

− If the customer's surveyor requests further checks of the tank container in addition to those detailed in thishandbook.

If the customer's surveyor has their own on-hire survey report and requests the Seaco surveyor to sign it; the

Seaco surveyor must not sign it unless all the following conditions are fulfilled:

− All codes used are clearly defined on form

− All comments relating to the condition and operating serviceability of the unit are in accordance with thoseentered on the Seaco form

− The customer's surveyor also signs the Seaco form

− The customer's surveyor provides the Seaco representative with a copy of his own on-hire survey report

The Seaco form is always the official report confirming the agreement between Seaco and the customerregarding the operating condition and serviceability of the tank container. The customer's own on-hiresurvey report does NOT take precedence over Seaco 's.




Page | 48

G. Pre-Delivery Inspection

This inspection must be carried out by the depot immediately prior to release of the tank container.

The depot prior to delivery to the customer must survey every tank container being delivered for which Seaco

has given release authorisation. In the case of special tank containers their individual requirements must bechecked.

The depot must ensure the tank container:

− Conforms to Seaco booking requirements by type, specification and last cargo

− Any special requirements detailed in the booking advice have been completed

− If it is more than 6 months since the on-hire inspection then the pre-delivery inspection mustinclude a leak check and new cleaning certificate

− Is fit for service according to Seaco’s repair requirements and quality standards, including specificrequirements for ‘special’ tank containers

− Must be fully operational according to the inspection criteria

− Interior clean and dry

− Valves closed, manlid and spill box secure

If the tank container is not repaired correctly, then it must be reworked.

− The cost of rework is for the depot's account

− Rework repairs must commence immediately and be completed in a timescale agreed with the local SeacoOperations Centre

− The unit must be re-inspected

Electrical - depot must complete a function test and retain the run test results.

Section 5: Identification of Manufacturers’Defects and Procedure forReporting Manufacturers’Defects

Contents of Section

Identification of Manufacturers' Defects (52)

Procedure for Reporting Manufacturers' Defects (53)

Appendix 5.1: Warranty Report forNew Defects

(55)

IDENTIFICATION OF MANUFACTURERS' DEFECTS

The inspector should be aware of the need to monitor tank container design and report potential manufacturingdefects and unsatisfactory design in addition to actual manufacturing defects.

Manufacturing defects must be identified and correctly reported on the repair estimate.

Typical defects might be those involving:

1. Fatigue Cracks

The most common fatigue cracks occur in the frame and at attachments between the frame and the tank. Alltank containers should be checked for any signs of stress related failure of either welds or parent material.

2. Weld Defects

Possible defects are porosity, lack of fusion or misalignments to welds. Defects to the frame and bearersupports are often revealed by cracks in the welds.

3. Defects Affecting ISO Dimensions

This type of defect is often identified after difficulties have been experienced in lifting a container by spreader.

Over tolerance variances in ISO dimensions are more often as a result of damage or previous improper repairrather than defects in the original manufacture. However, it may be that a design defect to the end frame hascaused misalignment.

Expansion of the insulation causing the insulation and cladding to exceed ISO tolerances is often the result ofmoisture ingress. It may be that defects to the security or water tightness of the cladding joints at manufactureare the root cause of the defect.

4. Paint and Surface Preparation

Inspectors should be alert for any signs of corrosion that do not appear to be the result of normal deteriorationor damage. Corrosion on a container of recent manufacture is a probable indication that the paint system is

defective.

The following are the most common types of paint related problems:

(i) Paint Film Detachment

The detachment of areas of the paint film in the absence of signs of sufficient impact or chemical contaminationis a sign of coating adhesion failure.

Such detachment may involve the top coat separating from the primer coat leaving the primer intact oralternatively the entire paint coating may detach leaving the bare steel substrate.

This type of failure is the result of lack of intercoat adhesion, poor metal preparation, contamination of thesubstrate or brittle paint.

(ii) Light Surface Corrosion

Light surface corrosion appearing through the paint film may indicate insufficient paint film thickness.Where the corrosion appears on the exterior of the painted stainless steel shell this is often due tocontamination by carbon steel particles at manufacture prior to painting.




Page | 52

(iii) Corrosion Blisters

This is the most serious type of corrosion and can cause much damage to the steel unless promptly treated.

Corrosion blisters form below the paint film and result in deep seated areas of rust and rapid decomposition ofthe steel.

In the early stages the blisters appear as small bumps beneath the paint film which at this stage is stillundamaged. As the steel starts to break down the size of the blisters increase until they break through the paintfilm. By this stage the corrosion process is well advanced and will have already significantly reduced the steelthickness.

(iv) Electrolytic Corrosion

Corrosion blisters described in (iii) above can occur around data plates and other metal components attached tothe container. This may be a result of using incompatible materials, usually the fasteners.

Corrosion of aluminium fasteners and aluminium cladding might also be a result of electrolytic corrosion.

5. Electrical FailureFailure of items such as printed circuit boards, thermostat contacts and heating elements may be due to amanufacturers’ design defect.

The common cause of defects to the above items is moisture ingress through joints in cladding and controlboxes as a result of defects at manufacture. However, previous improper repairs or failure to carry out repairsto damage on a timely basis must be investigated.

PROCEDURE FOR REPORTING MANUFACTURERS' DEFECTS

Potential Manufacturing Defects and Unsatisfactory Design

Depots and inspectors should report to Seaco any defect or design defects that may be present on a tank

container:

a) Design difficult to repairb) Design frequently damaged, orc) Vulnerable to damaged) Early deterioration, which although not a defect may become one

The procedure covers units of all equipment types. It applies both to new manufacturers' defects and alsoexisting manufacturers' defects.

For ease of reference the definition of new and existing manufacturers' defects is:

New Manufacturers' Defect

Any failure discovered on a unit which is less than 5 years old and which cannot be attributed to wear and tear,and which has not been identified in the Tank Fleet Survey by a TTB.

The age of the unit must be determined by reference to the Tank Fleet Survey, not by reference to the dataplate on the unit.

Existing Manufacturers' Defect Any failure which has been confirmed by Seaco to be a manufacturers' defect, and which has been eitheridentified in the Tank Fleet Survey or covered by a TTB or other formal circular instruction issued by Seaco.




Page | 53

PROCEDURE

1. New Manufacturers ’ Defects (New MD)

When a New MD is identified, the depot must without delay send to the local Seaco Operations Centre:

− A copy of the full printed Repair Estimate

− Clear photos illustrating the New MD. Each photo must be marked with the unit serial number, date ofphoto, location, name of inspector, returning lessee.

− A completed inspection report, using the standard Seaco Warranty Report form. No other reporting formatshould be use

An example of the Warranty Report is shown as Appendix 5.1.

Note: Up to five units may be entered on one form providing all the units are of the same manufacturer anddisplay similar defects.

2. Existing Manufacturer’s Defects(Existing MD)

For each unit on which an Existing MD is recorded, the following must be sent by the depot to the local SeacoOperations Centre:

− A copy of the full printed repair estimate

− Clear photos illustrating the MD (subject to exceptions listed below). Each photo must be marked with thesame data as listed above for New MD's. In addition the TTB reference number must be shown.

Note: Photos are not required for all existing MD's. TTB's will state whether or not photos are required (Inmost cases photos will be required for an initial period and then the requirement will be withdrawn).

Photos should clearly indicate the potential or actual problem. Photographs sent as a .pdf file should be namedto clearly state: -

Tank container serial number Date Depot or location where photo taken TTB number if applicable

. If photographs are sent in hard copy then writen On the rear of the photo the following must be clearly noted:

Tank container serial number Date Depot or location where photo taken TTB number if applicable

No Warranty Report or other inspection report is required for Existing MD's unless otherwise stated on theTTB.

Section 6: IDENTIFICATION OF FREQUENT MISUSE OF TANK CONTAINERS

Contents of Section

A container may be deemed to have been misused if it has been subjected to any of the following conditionswhich have resulted in damage:

− Used in excess of the designed working pressure (overpressure), or without ventilation (implosion) orexcess heat (over-heating)Handled by any means other than those specified in ISO document DIS 3874.Top side lift equipment (unladen tank containers only) must be of the full frame type. Handling by forkliftequipment is not permitted for tank containers

− Transported a cargo that has caused damage by reaction between the cargo and the container

− Transported by any vehicle or vessel which is not suitable for the carriage of containers

− Used when the operating or assembly instructions have not been followed or when necessary componentsare not present or correctly fitted

Complete the repair estimate as normal and immediately report misuse to the local Seaco Operations Centre.Containers subjected to misuse may be identified if they display characteristics such as:

Used in excess of designed working pressure

− Splits or distortion to steam tubes or shell. Excess steam pressure will additionally result in excesstemperature causing the insulation or exterior shell protective coating to char. Implosion will result in the tankshell or other components bowing inwards. It is caused by failure to vent the tank container after cleaning orwhilst discharging

Handled by any means other than specified in ISO document DIS 3874. Top side lif t equipment (unladentank containers only) must be of the full frame type

− Distortion of the top third of tank shell (chains too short)− Distortion of the manway area due to lifting by use of a yoke in the manway opening

− End frames leaning in towards the interior of the unit (chains too short)

− Permanent twist in the container about a diagonal horizontal axis (lifted by chains from two diagonallyopposite corner castings)

− Distortion to the underside shell, steam tubes or cladding (lifting by forks)

− Distortion to the side shell or cladding due to top side lifting without adequate support to the bottom side

− Distortion of the tank support bearers or movement of the tank within the frame due to the unit having beendropped

Transported a cargo that has caused damage to the tank container by reaction between the cargo andthe container

− General corrosion and staining

− Corrosion pitting− Stress corrosion cracking

− Damage to paint coating or cladding caused by spillage or storage in a chemical environment

Transported by any vehicle or vessel which is no t suitable for the carriage of containers

− Abrasion or damage caused by the use of makeshift lashing

Used when the operating or assembly instructions have not been followed or when necessarycomponents are not present or correctly fitted

− Implosion of the tank shell due to inadequate venting on discharge

− Implosion of the tank shell due to inadequate venting after hot washing

− Splits in the insulation and cladding due to operation of the tank container in excess of the maximum cargo

temperatures or charring of the insulation or shell exterior coating.− Damage resulting from disregarding assembly or security instructions

− Damaged valves and fittings due to improper tools (incorrect size wrench)

IMPROPER REPAIRS




Page | 59

Section 7: Improper Repairs

IMPROPER REPAIRS

An improper repair is any repair not performed where any one of the following defects is present:

- The repair has not been performed in accordance with ITCO/ACC recommended repair methods.

- The repair is of a quality or condition which could still be defined as damage according to the ITCO/ACCinspection criteria and Seaco guidelines.

- The repair has an adverse affect on the original ISO dimensions of the tank container.

- The repair affects the structural integrity or cubic capacity of the tank container.

- The repair compromises the safety of the tank container.

- The repair is not in compliance with the applicable regulations.

- Use of incorrect materials.

- Sub-standard preparation or painting.

- Poor quality welding or workmanship.

Not all improper repairs, as defined, need to be reworked.

A distinction has to be drawn between repairs in progress and therefore controllable and repairs already inexistence on a container, which is being considered for rectification.

All repairs carried out under the control of Seaco must be performed in accordance with ITCO/ACC repairprocedures. Any repair performed in a Seaco depot which does not meet the ITCO/ACC repair criteria shouldbe rejected and the container considered still damaged and unavailable for lease until the repair has been madegood in accordance with ITCO/ACC repair procedures.

Existing repairs which do not strictly meet Seaco requirements can be considered acceptable if they meet thefollowing requirements:

- The repair has been carried out in a competent manner using correct materials and a good standard ofworkmanship.

- Repairs to cladding which although unsightly, are watertight.

- The container conforms to CSC criteria.

- Repairs which may not have been properly cleaned and painted and are showing signs of superficialcorrosion.

NOTE: - Seaco must be informed when the inspector has any doubt about the integrity of an improperacceptable repair.

INTRODUCTION

ACCEPTABLE AND NOT ACCEPTABLE DAMAGE

The inspection guide which follows lists the component parts of a tank container and defines the tank Acceptable Container Condition (ACC) criteria for:

− Not Acceptable Damage/Condition

− Acceptable Damage/Condition

NOT ACCEPTABLE DAMAGE/CONDITION is damage that affects the safety, structural integrity, cargo-carrying capacity or the ISO dimensions, integrity of the tank container or not in compliance with the applicableregulations.

THIS TYPE OF DAMAGE MUST BE REPAIRED

ACCEPTABLE DAMAGE/CONDITION is minor damage or fair wear and tear which does not significantly affectany of the above conditions and therefore:

NO REPAIR IS REQUIRED.

DO NOT OPERATE VALVES/FITTINGS OR ENTER ANY TANK CONTAINER WHICH DOES NOT POSSESS A VALID CLEANLINESS CERTIFICATE AND VALID ENTRY CERTIFICATE.

OBSERVE THE SAFE INSPECTION PROCEDURES AND PRACTICE AS DETAILED IN SECTION 1 OFTHIS HANDBOOK AND ALL REGIONAL HEALTH AND SAFETY REQUIREMENTS.




Page | 63

1. CLEANLINESS

a) INTERIOR

Not Acceptable Damage/Condition

− Previous cargo, contamination or odour

− Discolouration, product residue or transferable stain which can be removed by manual application of aplastic abrasive pad and/or solvent

− Corrosion, pitting, grinding or gouges

− Missing or improper cleanliness certificate

Acceptab le Damage/Cond it ion

− Abrasions or scratches to finer than 120 grit polish equivalent

− Discoloration which cannot be removed by plastic abrasive pad or dull appearance

An Internal Shell Condition Chart must be completed for all interior shell defects. See Section 3 for details.

Note: Tank containers without a cleaning document must be considered unsafe and should not be inspected.

A cleanliness document is required for all tank containers prior to redelivery to depot for lease termination (off-

hire).

If the cleanliness document is not a cleanliness certificate the tank container may be off-hired but a cleanlinesscertificate is required and should be added to the off-hire estimate and issued by a qualified person.

Note: Where stains are present, clean a test area at the time of estimate preparation to both determine the costand ensure stains do not conceal corrosion pitting.

If heavily stained tank containers are redelivered, contact the local Seaco Operations Centreimmediately, to arrange re-cleaning prio r to of f-hire.

b) EXTERIOR


− Previous cargo, contamination

− Oil, grease deposits− Road dirt reducing legibility of tank container markings

− Significant and unsightly dust and dirt


− Road dirt, minor dust and dirt

Note: The valve and spill boxes must be clean and free of cargo spillage. Check areas of overspill for damageto paint and cladding and inspect drain tubes for blockage.

c) FOREIGN MARKINGS


− Hazard warning labels or cargo labels

− Non-standard labels or misleading marks− Remnants of labels

− Insecure or unserviceable label holders

− Customer logo or markings


− Serviceable label holders

− Minor glue residue

Note:

− Non-standard or damaged label holders should not be replaced. Remove and make good the area

− If a customer logo has been fitted over or in place of the Seaco or owners’ logo, the customer logo shouldbe removed. It is not necessary to renew the Seaco or owners’ logo (see part 12 of this section)

− Use overlay riveted patches as the standard repair

− Minimum patch size 150mm x 150mm

− Minimum thickness – GRP 2mm

− Minimum thickness – Alum Alloy 0.9mm (18 s.w.g.)

− Materials used should match original.

− Use overlay fibre glass tissue as the standard repair to formed GRP surfaces where riveted patches areimpractical

− Infill repairs should be used for holes less than 25mm to FRP/GRP

− Extend patches to the retainer strap where the patch is within 30 cm of the strap or if the patch requiressupport from the strap

− Care must be taken to ensure that drills or rivets do not damage the shell, steam tubes or electricalcomponents beneath the cladding

Multiple patches on panel

If the number of repairs or patches either present or required as part of the repair, distracts significantly fromthe aesthetic appearance of the tank container, then that section or panel must be replaced to achieve a moreaesthetic appearance to the tank container.

A number of small patches (multiple patches in the same area) can be repaired/replaced with a larger single

patch or a renewed panel in order to achieve a more aesthetic result. The patch material to be the same asoriginal material as possible.

13. TEST

a) Leak Test

Leak tests (pressurise with air at 1 bar) to tank and fittings are required under the following circumstances:

− As part of the depot survey to check the tank shell, valves, safety valves, steam and fittings

− As part of the completed repair inspection and quality process

− When tank containers are stored in depot for periods greater than six months from the time of the completedrepair inspection, a repeat leak test is required prior to delivery

This test does not replace the periodic leakage or hydrostatic test which is performed as part of the statutory 2.5or 5 year test procedures.

b) Leak Test Procedure

− The tank container should be pressurised with air as the pressurising medium. The test pressure should be

a minimum pressure of 1.0 bar and a maximum of 25% of the barrel’s Maximum Allowable WorkingPressure (MAWP)

− This test will be used to test the integrity of the tank barrel, valves, steam and fittings

− The pressurising medium should be introduced to the tank container and raised (slowly and with due care)to the required pressure. When the required pressure is reached it must be held for 10 minutes without lossin pressure

− The exterior flanges, valves and fittings must be checked for leakage by the application of soapy water.Leaks can be identified by the continual formation of bubbles in the solution when it is introduced around thearea being tested

− The internal seals to the bottom outlet valve should be tested using an apparatus similar to that shownbelow. Checking the foot valve and the outlet valve separately

− Due to the nature of the air test medium it might seep pass the sealing faces where a liquid will not leak.Because of this the surveyor might permit internal valve seals to seep an isolated bubble to one of thevalves in accordance with the manufacturer’s criteria

− Re-setting the foot valve (by opening and slamming) might be necessary to stop leaks


− Leaks


− Manufacturers tolerance as noted on next page

Set-Up to Leak Test Bottom Outlet Valve




Page | 85

Leakage Tolerance Criteria

c) Statutory Test

.

Determination of which statutory test to carry out must be based on the criterion below:

• A 2.5 year leak test should be carried out when a 2.5 year test is due (i.e. 2.5 years after the last 5 year test)providing the test is up to 3 months or less before or after test expiry

• Any tank container that requires a 2.5 year test but the test is more than 3 months after expiry date shouldbe given a 5 year test

• Any tank container that requires a 5 year test should be given a 5 year test• Any tank container arriving into depot with 9 months or less remaining test date should be detailed on the off

hire estimate for re-test

• Any tank container in depot under repair where the test date has 9 months or less remaining should betested at the time of repair

• Any tank container in depot where the unit is status ‘AVLB’ and the test becomes due within 6 monthsshould be tested (obtain authorisation via supplementary estimate procedure)

• Any tank container in depot to be delivered to a customer should have 6 months (or more) test validityremaining at the day of delivery (except when notified in writing to the contrary)

• 5 year re-testing is required after all welded repairs to the shell or conversion such as T11 to T14.

Note: Dangerous goods cargo may only be transported in a tank container that has a valid test certificate

CONVENTION FOR SAFE CONTAINERS(CSC)

1. INTRODUCTION

Every container must be checked on return to depot to ensure that it carries a valid data plate. This consolidateddata plate should incorporate a CSC plate. If the data plate does not include a CSC plate then this must be fittedseparately.

In addition every container must be checked to ensure that it is marked to indicate that it is operated underSeaco's Approved Continuous Examination Programme (ACEP). See paragraph 3 below for detailedinstructions.

2. FITTING A CSC PLATE

A new data plate must be fitted when:

−

The original data plate has been lost− The container has never been fitted with a data plate

Contact the local Seaco Operations Centre for the technical data, which must be stamped on the plate.

All letters and numbers stamped on the plate must be a minimum of 5mm in height. An example of a typicaldata plate and the data required is illustrated below.

The new CSC plate must be fixed in a readily visible place as close as possible to other existing approval platese.g. Customs Type Approval plate etc.

The majority of Seaco tank containers are fitted with a consolidated data plate, (as shown below).

Use 4mm diameter zinc p lated steel drive or self-sealing pu ll rivets to fix the plate to the tank frame.

3. MARKING THE CONTAINER TO INDICATE THAT IT IS OPERATED UNDER ACEP

Every tank container must be marked with the standard Seaco ACEP approval number or a decal bearing theapproval number ACEP-BDA-01 on or next to the CSC plate. This approval number is unique to Seaco and if adecal bearing any other approval number is found on the container it must be removed.

If the ACEP decal is missing, a decal bearing the above approval number must be fixed to the CSC plate in thesection entitled Next Examination Due. Alternatively, if there is insufficient space, fit the decal immediately nextto the CSC plate.

The standard ACEP decal is illustrated below:

Supplies of the Seaco ACEP decals can be obtained via Seaco Operation Centre.
