SECTION 2

2. GENERAL

2.1. After many years of debate and development, the International MaritimeOrganisation (IMO) adopted Annex VI to the MARPOL Convention in September

1997. This new Annex is entitled Regulations for the Prevention of Air Pollution fromShips." At the same time the IMO adopted the Technical Code on Control of Emissionsof Nitrogen Oxides from Marine Diesel Engines, usually referred to as the NOxTechnical Code or simply the Code.

2.2. MARPOL Annex VI and the NOx Technical Code (the Code) will come into force on19 May 2005.

2.3. MARPOL Annex VI applies to all ships2, and to fixed and floating drilling rigs andother platforms. Ships of 400 gross tonnage engaged in international voyages,constructed3 on or after 19 May 2005, are required to be surveyed and issued with anIAPP Certificate on delivery of the ship. For ships of 400 gross tonnage engaged ininternational voyages, constructed prior to this date, the IAPP Certificate must beissued at the first scheduled dry docking after 19 May 2005, but no later than 19 May2008.

2.4. The Code will apply to any diesel engine with a power output of 130 kW installedon a ship whose keel was laid on or after 1 January 2000, or any diesel engine with apower output of 130 kW which has undergone a major conversion on or after 1January 2000, except those intended solely for emergency use.

2.5. See Appendix X for the application of MARPOL Annex VI to existing ships.

2.6. The IMO has adopted a circular (MEPC/Circ.344), which states:

1 Each engine which will become, retrospectively5, subject to the provisions of regulation 13of Annex VI of MARPOL 73/78 upon its entry into force, should be certified in accordancewith the requirements of the NOx Technical Code.

2 Pending entry into force of Annex VI and upon satisfactory compliance with the Coderequirements, a "Statement of Compliance" with the NOx Technical Code should be issued bythe flag State Administration or an organisation acting on behalf of that Administration

SECTION 3

3. MARPOL Annex VI - General Surveys and Certificationrequirements

3.1. Surveys and certification will be required in a similar manner to the requirements for

the familiar MARPOL Annex I and associated IOPP certificate.

3.2. MARPOL Annex VI requires that every ship of 400 gross tonnes or above and everyfixed and floating drilling rig and other platforms are surveyed and issued with anInternational Air Pollution Prevention (IAPP) Certificate. The survey andcertification procedures will generally follow the same format as those for MARPOLAnnex I, IOPP certificates.

3.2.1. Ships of 400 gross tonnes and above and every fixed and floating drilling rig andother platforms must be in possession of an IAPP Certificate. For ships under 400gross tonnes, the flag administration may establish alternative requirements, forcomplying with the provisions of Annex VI.

3.3. An IAPP certificate will be valid for five (5) years from the date of the initial surveywhile its continued validity will be maintained by annual, intermediate and renewalsurveys. The surveys follow the IMO Harmonised System of Surveys andCertification (HSSC).

3.4. In the period leading up to the Annex entering into force LR can on request issuecertification to demonstrate that a ship complies with the applicable regulations ofMARPOL Annex VI. LR can also test and certify that diesel engines comply withRegulation 13 of MARPOL Annex VI and the NOx Technical Code.

3.5. Surveyors will determine any additional or specific Flag requirements prior tocommencement of a survey.

3.6. In the case of ships of less than 400 gross tonnage, the Administration may establishappropriate measures in order to ensure that the applicable provisions of MARPOLAnnex VI are complied with.7

SECTION 4

4. MARPOL ANNEX VI SURVEYS - General requirements

4.1. A survey is conducted to confirm that the arrangements and equipment will, withproper maintenance be expected to remain in good condition and working orderuntil the next survey.

4.1.1. MARPOL Annex VI surveys will normally be dealt with in their entirety and not aspart surveys.

4.1.1.1. Only on those occasions where the required service facilities or necessaryreplacement equipment is not available locally would items be considered fordeferment.

4.1.1.2. Surveys should only be held within the permitted range dates, with a certificateceasing to be valid if the periodical, intermediate or annual survey, as appropriate, isnot completed within the periods specified in the relevant regulations.

4.1.1.3. Carrying out the appropriate survey will restore the validity of the certificate. Thethoroughness and stringency of this survey will depend on the time the survey wasallowed to lapse.

4.1.1.4. When a survey is requested to be held after the expiry of the range dates, the Owners

will be informed in writing that the Certificate must be considered as having beeninvalid from the expiry of the range dates until the date the survey was held.

4.1.1.5. Renewal surveys should be completed before or by the expiry date of the certificate.

4.1.2. Should an LR Surveyor become aware that the condition of the ship or its equipment,does not correspond with the particulars of any of the statutory certificates or thecondition of the ship is such that it is not fit to proceed to sea, without danger to the

ship or persons on board, or presents an unreasonable threat to the marineenvironment, the Surveyor will recommend repairs to rectify the deficiencies.

4.1.2.1. If the Surveyors recommendations are not carried out, the certificate will bewithdrawn in accordance with the requirements of MARPOL Annex VI. The Masterwill be advised in writing that the certificate is to be surrendered and that thecertificate is invalid from the date of the letter A copy of the letter will be forwarded


7/51



4.1.3.2. Periodical or Renewal Surveys will, in addition to the requirements of an Annual and

Intermediate Survey, be such as to ensure that the equipment, system, fittings,arrangements and materials fully comply with the applicable requirements ofMARPOL Annex VI.

4.1.3.3. An Annual Surveys will consist of:

4.1.3.3.1. verification that the certificate on board is in order,

4.1.3.3.2. an examination of the various items of equipment together with tests as considerednecessary, all to an extent which, in the Surveyors judgement, indicates adequatecondition and standard of maintenance sufficient until the next due Survey.

4.1.3.4. An Intermediate Survey will consist of:

4.1.3.4.1. an Annual Survey, plus

4.1.3.4.2. a thorough examination to ensure that the equipment complies with therequirements of the Regulations and is in good working order, sufficient until thenext Survey.

4.1.4. To assist in preparing for the survey, a draft provisional survey checklist has beendeveloped. (Refer to Appendix IX)


8/51



SECTION 5

5. REPORTING AND CERTIFICATION

5.1. The surveyor will complete the checklist (see Appendix IX) during the survey onboard the ship to ensure all relevant aspects are verified. Where necessary,

supplementary sheets listing specific information on the systems accepted will beappended to the check list report.

5.2. On completion of the Initial Survey, the Surveyor completes the report and issuesthe IAPP Certificate or Certificate of Compliance.

5.2.1. A copy of the survey report and certificate will be sent to the central certificatesdatabase, from where it can be viewed and retrieved via CDLive. This ensures the

information is available to surveyors undertaking subsequent surveys.

5.3. A copy of the report and any certificate issued will be made available to the FlagAdministration as and when required.

5.4. On satisfactory completion of the Intermediate/Annual Survey the IAPP certificateon board will be endorsed to show that the survey has been completed.

5.5. On satisfactory completion of a Renewal Survey a new certificate valid for a

maximum of five years (taking into account the requirements of the HSSC whereappropriate) will be issued with a copy of the survey report and certificate sent to thecentral database

(ii) any other equivalent method, approved by the Administration taking into accountrelevant guidelines to be developed by the Organisation, is applied to reduce onboardNOx emissions at least to the limit specified in sub-paragraph (a) of this paragraph.

6.2.1 General requirements

6.2.1.1 MARPOL Annex VI requires all diesel engines with a power output of more than 130kW to be tested and issued with an Engine International Air Pollution Prevention(EIAPP) certificate and an approved NOx Technical File. This EIAPP certificate andapproved Technical File stays with the engine and remains valid for its marine life.

Periodic verification surveys are carried out to confirm the engine continues tooperate within the on-board NOx emission limits.

6.2.1.2 Emergency diesel engines, lifeboat engines or any other engines installed inequipment intended solely for emergency use, do not have to comply withRegulation 13 of MARPOL Annex VI.


13/51



6.2.1.5 Each EIAPP certified engine is subject to an on-board verification survey afterinstallation on-board as part of the initial IAPP survey. This verification procedure,contained in the Technical File, is approved from the following available methods:

Engine parameter method.

Simplified measurement method.

The direct measurement and monitoring method.

6.2.1.6 Where an engine has no EIAPP certificate, (i.e. not pre-certified) certification will berequired prior to issue of the ship's IAPP certificate. Normally this will entail emissiontesting of the engine on-board in accordance with the full test bed requirements or, inextreme circumstances removing to a test bed.

6.2.1.7 Note: It is the ShipOwner who nominates the method to be used to demonstratecompliance, not the flag state authority. The flag state is responsible for the acceptanceand approval of the method. The engine builder will need to supply the necessarysupporting equipment, facilities and information from the outset.

6.2.2 Initial on-board verification Survey.

6.2.2.1 The survey will consist of:

6.2.2.2 Identifying which engines are required to be certified and have an approved NOxTechnical File, and that they all have NOx Emission pre-certification (EIAPP).

6.2.2.3 A review of the engine certificates and NOx Technical Files including ensuring that theNOx Technical files have been approved.

6.2.2.4 Verifying:

The engine, its components, settings, and operating values remain within the limitsspecified in the approved NOx Technical File by performing the on-boardverification procedure.

The duty stated on the EIAPP certificate equates to the installed duty, e.g. D2 =constant-speed auxiliary application, etc.

That the cooling system is in line with that approved for the installation.

Guidance on Marine Engine On-board Verification Survey.

INTRODUCTION

This survey is carried out after installation on board the ship to verify the engine's components,settings and adjustments remain within the limits established at the NOx emission test bed trial (Pre-certification) as recorded in the approved Technical File. Provided these conditions are maintained,the engine is considered to remain operating within the NOx Emission limit for its category, t beingaccepted that if the NOx sensitive components and settings remain the same, then the engine willremain compliant with the NOx emission limits. Thus, it is not necessary to carry out another NOxemission test.

A verification survey of the engine is required where modifications or adjustments to the designated

components and adjustable features have been carried out since the last survey. This informationshould be available from the engine's record book of engine parameters37 where all modifications,repairs, adjustments, component replacements, etc., are recorded.

At each survey the engine would be inspected in accordance with the approved procedure in theTechnical File. The degree of stripping down would be sufficient to allow the NOx sensitivecomponents, settings and adjustments to be verified. In the real word this may not always bepossible, though still desirable, thus we need to consider the tools currently employed for engine

surveys and use them to our advantage without losing sight of the Surveyors responsibility under hisauthorisation to carry out this statutory survey. Whichever combination of methods are used, theymust provide verification and confidence that the engine remains in compliance.

The surveyor shall have the option of checking one or all of the identified components, settings oroperating values to ensure that the engine with no, or minor, adjustments or modifications complieswith the applicable emission limits and that only components of the current specification are beingused. Where adjustments and/or modifications in a specification are referenced in the technical file,they must fall within the range recommended by the manufacturer and approved by the

Administration..

Where a combination of methods are used to verify compliance, such methods will be applied withdue care and diligence by surveyors who through experience understand the techniques along withtheir limitations.

Survey Methods.

Warning, this is not a list of acceptable alternatives to direct survey, but methods which may beutilised periodically in conjunction with the direct surveys while still maintaining confidence in theengine's compliance.

The Technical Code Procedure. (This will always be the preferred method).

The Technical Code specifies requirements for the on-board verification survey.

Documentation Review. A review of the documentation for each engine which includes theengine parameter book to ensure the components, settings and adjustments recorded remainwithin the designated limits. This may be supported by the engine log book.

Carrying out the on-board verification survey in accordance with the procedure provided in theengine's NOx Technical File.

Where an engine is provided with an after treatment device such as an SCR (Selective CatalyticReduction) system, a check of its operation forms part of the survey. This holds true for otherNOx abatement systems such as for injection of water, steam, etc., into the cylinder or fuel to aidcombustion.

Additional Survey Tools.

These may be used in conjunction with the direct survey procedure to limit the degree of opening upat intermediate surveys. For renewal surveys, it is recommended the full survey is conducted.

Classification surveys. Allows verification inspection of NOx sensitive components while theengine is open (dismantled) for survey. This can be a very useful tool provided the verification isthorough and the information properly recorded in the survey report such that it is available foruse at future surveys.

Operational test under load. Allows comparison and assessment of the engine operatingparameters against those in the approved NOx Technical File. This could be used to limit thedegree of opening up required after confirming the easily accessible components and settings areacceptable. Useful for the smaller engines driving pumps, etc. Also for generators which are inoperation, where it is not feasible to carry out the full direct inspection.

The following provides a general guide for some of the main components, settings and adjustments,which may be encountered during a survey38. When carrying out the survey, the surveyor will usethe On-board NOx verification survey procedure provided in the approved NOx Technical File, whichlists the specific information and data for the engine under survey.

Combustion Chamber and Compression Ratio

The approved on-board survey method will define how to carry out the inspection/verification of

the various parameters or parts and can vary between manufacturers. The following are provided asguidelines where this is not clear or alternatives may be considered.

Verifying the cylinder head, piston, piston rod (connecting rod) and shims where relevant, would bethe normal method used. However, the compression ratio may be checked by taking compressionreadings for each or selected cylinders. Other means are to check the travel of the piston and toverify that the correct shims have been used where applicable. Care must be taken, since the wrongtype of cylinder head or piston could alter the combustion space characteristic geometry, i.e. flow /

swrill. This may not be easily observed from travel measurements only. Variations in thecombustion space / geometry can have an effect on the NOx emissions produced due to changes inthe combustion process.

Cylinder Head

Normally identified by its identification number (ID), which is usually in an accessible positionwithout opening up.

The NOx emissions may be altered if the combustion chamber geometry of the cylinder head is

modified, affecting NOx formation mechanism and therefore emission characteristics.

ID Number

Turbo-chargers

Turbo-chargers are sized to suit the engine power and operating characteristics. Therefore changesto their component parts (impellers, diffuser, etc.) will affect the combustion and hence the NOxemissions. Each major component is marked and at classification surveys their NOx identificationnumber should be verified. Then at periodical Annex VI surveys it would be sufficient to verify thecorrect type of turbo-charger is fitted provided no modification had been carried out. Modification

details can be confirmed from the records in the engine book of engine parameters.

Charge Air Cooler and Cooling System

The temperature of the cooling water controls the temperature of the combustion air, which has acontrolling effect on the engine combustion and thus the products of combustion. The cooler istherefore sized to ensure optimum engine operating parameters with a sea water temperature of25C. Hence the importance of verifying the cooler is the correct one for the engine. This can bechecked by the ID on the cooler nameplate. The cooler should be maintained in good condition with

effective sealing between the two media.

Note: The Technical File is approved for a particular cooling system and associated temperature setpoints. Always consult the approved survey procedures for that engine.

Fuel Injection, Timing and Timing Control System

The injection timing, the injector nozzle, injection pump or the fuel cam, all affect the NOx emissioncharacteristics or an engine.

The injector nozzle will be marked with the ID on the nozzle. This is easy to remove and check. It isimportant since a different number and/or size of holes in the nozzle can affect the combustion and

hence the NOx emissions. Also an incorrectly set injector opening pressure can affect thecombustion. This may be identified from the exhaust temperatures and indicator cards. Withregular maintenance this should not present a problem.

Cooler IDnumber

MARPOL ANNEX VI


September 2004

The fuel pumps may be in a block or individual depending on the engine type and configuration.The fuel may be delivered via a common rail or by individual pumps to each injector with theinjector opening and closing by either electronic or mechanical control. The fuel pumps are markedwith an identifier and type designation, which may be checked without dismantling completelydepending on the type fitted. For some pumps, the plunger travel is measured by a special tool afterremoval of the discharge pipe while for others it is possible to verify by removal of the side plugs andturning the engine over to note the discharge and cut-off points in relation to the camshaft markings.Electronic control units have an ID number and are normally sealed. Where adjustments are

required, these may only be made by an authorised manufacturer's representative.

Note: Fuel Pumps in the common rail system are not defined as NOx sensitive components.

Injection timing depends on the system employed. Many of the smaller engines (Member's offamily) use pre-set electronic timing, which cannot be adjusted by the ship's staff.

In other engines, (e.g. members of an engine group) the timing can be altered by re-positioning thecamshaft, the timing chain, drive wheels or fuel cam or its profile or software parameters in commonrail applications. These items are all marked with an identifier plus the original settings to facilitate

verification checks. They can normally be reviewed by the removal of a cover and turning the engineto the correct position in accordance with the approved procedure.

Q How will Air Pollution from ships be controlled?A Annex VI controls six areas of air pollution from ships: --

A prohibition on the discharge of ozone depleting substances

Emissions of nitrogen oxides -NOx

Emissions of sulphur oxides - SOx.

Volatile organic compound emissions from tankers

Incinerators emission controls

Fuel oil quality

Q What certification can LR offer?

A If requested by a shipbuilder or an Owner, LR can offer the following certification andsurveys.

A statement indicating the degree to which a ship complies with the MARPOLAnnex VI Regulations which were verified at the Owners' request.

This would be a statement of fact stating the ship had been surveyed, with details of theregulations it complies with at the time of survey. The statement would have no period ofvalidity and no further surveys would be required

ABCDQ Can LR issue certification on behalf of national administrations?

A Most administrations have indicated that LR can issue Annex VI certification on theirbehalf. Other administrations have indicated that an LR certificate or statement ofcompliance would be sufficient evidence of compliance to issue an IAPP certificate onceAnnex VI comes into force. This would be issued either by the Administration or on theirbehalf by an authorised representative. Surveyors will determine any additional or specificFlag requirements prior to commencement of a survey.

Q Can an IAPP certificate be issued?

A IAPP certificates can be issued when MARPOL Annex VI comes into force on 19 May 2005.One notable exception is for UK Flag ships, where IAPP certificates should be issued assoon as possible. In the interim period Interim IAPP Statements or Certificates ofCompliance can be issued.

Q Can LR certify diesel engines for compliance with the NOx Technical Code?

A Yes. However, procedures for NOx Code certification are not dealt with in theseguidelines41.

If a request is received for NOx Code certification, contact Design Appraisal (DAPP)Engineering Systems, London Plan Approval for instructions.
