1. Introduction 1. Introduction 1. Introduction 1. Introduction Lloyds Registers verification requirements and procedures for new construction are to be built under the regulations detailed by the documents listed below, collectively referred to as PSPC-BWT in this document. The related standards and documents for reference are:
It is anticipated that a pre- job meeting and agreement will be carried out and form the basis of the verification guidelines, this should include the items listed below but not be limited to this:
Confirmation of the coating suppliers, if not already agreed. Coating Specification. Treatment of fixtures and fittings, if not included in the coating
specification. Inspection schedule and standards. Number of tests to be carried out e.g. salt tests, profile assessment,
dust tape tests etc. Applicators working procedures and equipment including e.g.
supervision organisation chart, experience of supervisors and operatives, access to surfaces (staging), lighting, equipment capacities and availability etc.
Applicators QC procedures (e.g. monitoring of ambient conditions / ventilation and pre-official inspections for surface preparation, cleaning, DFT etc.)
Communications including procedures for calling inspections (e.g. minimum acceptable advance notice and acceptable hours, including weekends evenings, holidays). Also procedures for informing LR of forthcoming inspections.

LR will complete a CTF Check List for each vessel to which the PSPC-BWT regulations apply.
Inspection procedures have been agreed between the shipyard, the ship owner and the main coating supplier before work is started. These are most likely to be discussed and agreed at a pre-job meeting or meetings. The pre-job agreement must satisfy all of the requirements of the PSPC-BWT and the shipyard is to present the minutes of the agreement to LR for review. LR may also request to participate in the pre-job agreement process.
That the Shop Priming Plant Verification Report (see Appendix 2) is
available for the pre-job agreement process and that the standards achieved are acceptable to the shop primer supplier, the main coating supplier and the Approved Inspector.

If the shop primed steel is purchased from a location or supplier different from the shipyard, the steel shall have all the relevant quality control documents from that supplier or location, and that the local LR surveyor has witnessed and also supplied the relevant completed forms. This also includes finished or semi-finished blocks supplied from a different site or manufacturer.
The shop primer must be approved in accordance with PSPC-BWT
otherwise it must be removed.
The Approved Inspector should participate in the shop primer verification process as early as possible after being appointed. The Approved Inspector will then be included as a signatory in the verification process. It may also be decided that the main coating supplier participates in the verification process.
The shop-priming plant documentation may require modification depending upon the agreed inspection bodies.
The date of the verification must be valid from the start of plate processing.
2.2 2.2 2.2 2.2 During During During During coating applicationcoating applicationcoating applicationcoating application For Approved Inspectors unknown to Lloyds Register, verification will be required as early as possible in the contract. For inspectors known to LR or when acceptable standards have been established, spot check verification is acceptable. LR will record their monitoring verification details in the LR Form1215.Form1215.Form1215.Form1215.
For automatic shop primer application regular audits of QC records, without a physical check of the plants operations is acceptable. NoteNoteNoteNote: LR is to confirm that the ship yards QC system ensures that all calibration certificates for inspection instruments are maintained up to date. If not, LR will require all current certificates for review. All sections of the form form form form 1215121512151215 pertaining to the relevant sections of MSC.215 (82) section 6.2 and SC223 shall be completed on a regular basis and be retained for future reference.

Verification Requirements:Verification Requirements:Verification Requirements:Verification Requirements: Through document audits and / or physical spot checks, that all the requirements of the PSPC-BWT are fulfilled.
Monitoring of the coating inspection requirements, as required by the MSC.215(82) (Section 7.5) means checking, on a sampling basis, that the inspectors are using correct equipment, techniques and reporting methods, as described in SC223. This will require that the Approved Inspector physically demonstrates to the LR Surveyor that inspection procedures are properly carried out and are accurately recorded in the appropriate reports. Examples of these reports are shown in Appendix 3.
An appropriateappropriateappropriateappropriate level of inspection should be agreed within the pre-job agreement, for example:
Approximately 10% of block inspections. A minimum of two hull stage tank inspections A minimum of two pre-delivery tank inspections.
The Approved Inspector should be able to show compliance to items listed in Appendix 1 and Appendix 2.
Note:Note:Note:Note:
Non-conformances are to be documented in a Non - Conformance Report (NCR) and closed off by the Approved Inspector after correction.
Non-conformances are considered non-compliances, if the shipyard or contractor refuses to repair, or where the repair is to be carried out later in the contract, when the NCR will remain in place to act as a reminder.
Routine requirements for repair after inspection will not be subject to an NCR if repair is to be carried out immediately. Inspections resulting in rejection should be detailed in the Preparation & Application Progress Report.

The Hull Stage Tank report requires that the damaged area be estimated and recorded If damages are to be blasted, a minimum area per damaged spot must be agreed prior to the start of blasting and steps taken to avoid over blast damage. Small isolated areas of damage should be mechanically repaired. If widespread small damages are present then the entire affected area should be blasted to avoid unnecessary over blast damage.

Batch number of both the base and curing agent to be recorded in the coating report. Normally only one batch will be required for any single area. The Approved Inspector must agree if more than two batches are to be used in any area and record the reasons in the Preparation & Application Record.
Note; The PSPC does not specify ambient conditions during surface preparation: it is important, however, to confirm that ambient conditions required for coating are achieved before the cleaning inspection is started. If ambient conditions do not meet dew point/RH/surface and air temperature criteria, the quality of surface preparation is likely to deteriorate before application of the first full coat and stripe coat is complete. Coating application should commence as soon as possible after surface preparation has been accepted and must be completed before any visible deterioration has occurred. Separate preparation and cleaning inspections may be preferred to avoid re-cleaning if surface preparation is not accepted. Depending on shipyard practice, however, cleaning and surface preparation inspections may be carried out simultaneously. Loose spatter should be removed before the cleaning inspection. Cleaning inspections should always be carried out from the top of the area down.

The sequence of stripe coats will normally be agreed at the pre - job meeting. It may be that both stripe coats are applied between the first and second full coats. Normally each full coat and intermediate stripe coat will be a different colour to its substrate. If the second stripe coat is to by applied after the second full coat it is normal practice to apply the same colour as the last full coat. The extent of the second stripe coat will be agreed at the pre-job meeting

1.1.1.1. Inclusions to be removed and repaired according to the suppliers recommendations
2.2.2.2. Sags, runs and puddles if present, will normally be caused by poor application technique. In exceptional cases the cause may be a batch or formulation problem.
3.3.3.3. Defects such as craters, pinholes & bubbles may be causes by surface contamination or surface condition, ambient conditions application techniques or problems with the product. If present, the cause should be investigated immediately to avoid re-occurrence in other blocks or tanks.

SSPS-PA2:2004 & PSPC Annex 3
LR will confirm that the DFT procedures as detailed in PSPC Annex 3 are being followed by the Approved Inspector. The Approved Inspector will demonstrate to LR by a series of spot checks that measurements are taken in the areas as required by the PSPC. The Approved Inspector will also demonstrate that measured DFT's are in accordance with the Type Approval Certificate, the PTDS and the PSPC. Note; The PSPC refers to NDFT (Nominal dry film thickness) and a 90/10 rule. This means 90% of all thickness measurements shall by greater than, or equal to the NDFT, and none of the remaining 10% shall be below 0.9 x NDFT (See Table 1.1,5 of the PSPC). Excessive thickness must also be avoided and be within the coating supplier's maximum values quoted in the PTDS It is not the responsibility of LR to verify the overall condition of the block or tank or to carry out the verification without the presence of the Approved Inspector.
Excessive thickness: To be repaired in accordance with the suppliers recommendations
Note:Note:Note:Note: The Pre-delivery (Completion) Inspection should be carried out after sea trials / ballasting whenever possible.
