1. Introduction Lloyd’s Register’s 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.

MARINE SERVICES

Applicator’s 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.

Reporting procedures and report formats (see Appendix 3 for recommended reporting templates).

Procedures for reporting non-conformances and resolving their satisfactory repair.

Appointment of the inspection body or bodies (i.e. shipyard, coating supplier, ship owner, independent or a combination of two or more).

Clarification of how many inspectors will be required. Assistance to be given to the inspectors. Names and qualifications of inspectors (copies of current

certificates including information to allow traceability and confirmation will be required).

Procedures for the settlement of disputes. Health and safety.

The Lloyd’s Register PSPC-BWT new building verification process for surveyors can be broken into three stages:

i. Before coating application is started.

ii. During coating application.

iii. After coating completion and prior to ship delivery. Any deviation should be raised to the shipyard, or the Approved Inspector, as deemed appropriate by LR. In the event of corrective action a Class Certificate will not be issued until all corrective actions have been closed out. 2. Verification Requirements by the LR Surveyor 2.1 Before coating application is started The minimum PSPC-BWT requirements are included in the CTF check list (see appendix 1). The CTF is to be compiled by the shipyard before work is started. Notes:

The minutes of the pre – job agreement are to be reviewed by LR.

2013 Version 05 4

MARINE SERVICES

Selection of coating System - See MSC 215(82) Table 1.1. The criteria for selection are to be confirmed by the shipyard, ship owner and coating supplier.

PSPC Type Approval Certificate or Statement of Compliance. Details are held at LR London.

The PTDS will comply with The Type Approval Certificate. The Coating Specification will include at least the following:

Shop primer.

Manufacturer. Name of Product. Code of Product. Type. Specified DFT. Surface Preparation. Compatibility with the main coating.

Main Coating Manufacturer. Name of Product. Code of Product. Type. Number, sequence and colour of Full coats. Method of Application (Airless Spray). NDFT of Each Coat. NDFT of the Total System. Number, sequence and colour of Stripe coats including

method of application.

Surface preparation requirements will include Intact shop primer. Corrosion. Broken down and damaged shop primer. Block pre-erection (if applicable). Erection welds. Main ballast coating damages.

The MSC.215(82) specifies minimum surface preparation and application standards.

Any additional requirements of the coating supplier, Flag, Class or Owner should also be included into the specification.

All interpretations shall be in compliance with SC223.

The inspection and coating procedure stages should be agreed between the ship-owner, shipyard and coating manufacturer.

2013 Version 05 5

MARINE SERVICES

Bodies responsible for inspection are required to provide the names of their respective Approved Inspectors, together with verified copies of the inspector’s certificates. Evidence will be available to confirm that all certificates are current. If there is to be more than one inspection body, there must be a clear line of authority.

Typical examples of the builder’s quality control documentation include the following:

Shop Priming Plant Verification and Daily Record. Daily Log - To list all inspections for each working day. Preparation & Application Progress Report. Block Report - Secondary Surface Preparation & Cleaning

Inspection Report. Pre-Erection joint Report -Secondary Surface Preparation &

Cleaning Inspection Report. Hull Stage Erection Joint & Damages Report -Secondary

Surface. Preparation & Cleaning Inspection Report. Block Report- Coating Inspection Report. Block Pre-erection / Hull Stage Coating Inspection Report. Pre-Delivery Inspection Report - (Completion Report). Non Conformity Report.

The format of reports may vary as agreed between the shipyard, ship-owner and the Approved Inspector but must comply with the requirements of the PSPC-BWT. Note: The shop priming plant QC procedures will normally be subject to a separate audit by the Approved Inspector. The minimum QC Working Report contents for the PSPC-BWT (See MSC.215(82) 3.4.2) are:

Applied Actual Space and area (in square metres) for each compartment.

Applied coating system. Time of coating, thickness, number of layers. Ambient conditions during coating. Method of surface preparation. Statement by the Approved Coating Inspector that the

coating was applied in accordance with the specifications and to the satisfaction of the coating supplier representative. Deviations from the specifications and their correction will be reported.

LR will confirm the relevant boxes in the CTF Check List and the Shop-priming Plant Verification as appropriate before work is started.

2013 Version 05 6

MARINE SERVICES

Verification Requirements: All documentation required to satisfy the terms of the PSPC-BWT has been prepared by the ship-yard as listed in the CTF Check List. 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.

2013 Version 05 7

MARINE SERVICES

2.2 During coating 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.

For automatic shop primer application regular audits of QC records, without a physical check of the plants operations is acceptable. Note: LR is to confirm that the ship yard’s 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 1215 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. Details will include:

Area inspected. Date & time. Official report number. Block or location on the vessel. Approved Inspector’s findings. Any unresolved disagreements between inspection bodies

and the eventual outcome. NCR details, if applicable.

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 representative 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 appropriate level of inspection should be agreed within the pre-job agreement, for example:

2013 Version 05 8

MARINE SERVICES

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:

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.

2.3 After coating completion and prior to ship delivery Verification Requirements:

The shipyard has completed the CTF in accordance with the PSPC-BWT and that all relevant documentation required for the CTF is included.

That the Approved Inspector(s) has signed all the relevant

reports confirming that standards complied with the MSC.215(82) and all other agreed documentation, the PTDS and were carried out to the satisfaction of the coating supplier's representative.

That the owner has been given a copy of the CTF for

placement onboard.

Note: The CTF should include the maintenance specification.

Item

PSPC Requirement Comment

Before Start

Steel dressing & Pre-Cleaning

Removal of sharp edges ISO 8501-3 Grade P2 (2mm radius)

All sharp edges should be rounded to a minimum of 2 mm radius. The PSPC requires 3 pass grinding however, other methods will be acceptable to LR provided the required standard is achieved.

Removal of undercuts/laminations/ spatter/other steel defects

ISO 8501-3 Grade P2

Removal of oil and grease To be removed Visual or Water droplet test - Water must wet out surface to be tested. (UV lamp may be proposed but this method will only be effective with certain types of oil and grease)

Surface Preparation Welds and corroded areas

Damaged Shop primer

Sa 2½ ISO 8501 – 1 Profile 30μm to 75μm ISO 8503-1 and 2

The ISO 8503 Comparator method does not include grade 30μm to 75 μm. The profile will therefore be judged using the appropriate medium grade comparator. Note that there are two types of comparator, one for grit and one for shot.

Bloc

ks

Intact shop primer See the coating’s Type Approval Certificate The ‘Type Approval Certificate’ PTDS and the PSPC will indicate the minimum required standard of preparation.

Erection Joints St 3 ISO 8501 - 1 or Sa 2½ ISO 8501 - 1 Blast profile as above

The coating supplier may require a minimum surface profile after grinding / discing (see PTDS). If areas are to be blasted suitable procedures should be place to avoid over blast damage.

Damages St 3 ISO 8501 - 1 or Sa 2½ ISO 8501 - 1 -Blast profile as above

If damages >2 % of the total area then blasting to Sa 2½ is mandatory. 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. Note over blast damage can be very difficult to see, hence the importance taking adequate steps for its prevention. .B

- The agreed method of abrasive cleaning must be acceptable to coating supplier and ensure acceptable inter-coat adhesion.

Soluble Salt test - Surfaces ISO 8502-9 or NACE SP0508-2010 ≤ 50 mg/m2 (250 μS/cm)

The minimum number of tests per block or tank should have been agreed at the pre - job meeting. Additional tests may be necessary depending on conditions at the time of verification. PSPC requires a minimum of one test per block. Sampling should be by Bresle Patch or similar (Size A-1250 i.e. 1250 ± 13 mm2) and conductivity measured in accordance with ISO 8502 – 9. Tests areas should focus on areas most likely to be contaminated or on areas likely to have been 'missed' during the cleaning process e.g. behind bars, tank floors, areas of corrosion etc.

Appendix 2 – B1 (cont) PSPC- BWT VERIFICATION PROCEDURES

These Guidelines are intended to assist in the LR verification and should be used together with the working procedures agreed in the Pre-job Meeting and the LR Shipyard Auditing/Gap Analysis Guidelines. LR is to check, on a sampling basis, that the Approved Inspector uses correct equipment, techniques & reporting methods

Item PSPC Requirement Comment

After surface Preparation and before 1st coat

Dust removal ISO 8502 -3 Rating 1 Class '3',4' or '5'

The dust quantity rating is not to exceed quantity rating 1 for dust classes ‘3’, ‘4’, or ‘5’. Dust of lower classes is to be removed if visible on the surface without magnification.

Air Temp °C RH ≤ 85% Steel Temp ( ≥ 3°C than Dew Point) Dew Point °C

Q.C. to monitor conditions during and after application until work is completed.

Drum identification and batch number to be verified

To comply with the PSPC and the PTDS

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 tank top down.

After 1st Spray Coat application Coatings to be free from:

Sags, runs and puddles Craters Pinholes Bubbles Holidays Inclusions Other defects

Steps must be taken to avoid similar problems in the future

See section H - final coat verification. If defects are widespread or if considered significant the cause must be urgently investigated. If necessary coating activities should be halted until the cause of the defect is remedied.

DFT Spot Check Flat surfaces Longitudinal stiffeners Transverse stiffeners and girders Large brackets and primary supports Around openings Areas Inaccessible by airless spray

As considered necessary by the Approved Inspector.

Excessive thickness removed To be repaired in accordance with the suppliers recommendations. Before subsequent full coats and stripe coats

Over coating interval To comply with the PTDS See section 3.4 above Adequate ventilation in place Bulk contamination removed Dust removal Inclusions Air Temp RH Steel Temp Dew Point Drum identification and batch no verified

Same as section 3.4 but with confirmation of acceptable over coating interval and the exclusion of salt tests, unless contamination is suspected) . Inclusions to be removed and the coating repaired in accordance with the suppliers instructions.

Inclusions Pinholes Sags, runs and puddles Other defects

See Section 3.8

Film Continuity Welds Edges Cut outs Areas Inaccessible by airless spray

Scallops & rat holes etc. to be verified using a mirror as necessary The substrate should not to be visible

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

Final Coat Verification

1. Inclusions to be removed and repaired according to the suppliers recommendations 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. 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.

Coatings to be free from: Inclusions Sags, runs and puddles Craters Pinholes Bubbles Other defects

Steps must be taken to avoid similar problems in the future

Depending on the extent of the defect it may be necessary to halt production until the problem can be resolved. Film Continuity:

Flat surfaces Welds Edges Cut outs Areas inaccessible by airless spray

Scallops & rat holes etc. to be verified using a mirror as necessary. The substrate should not to be visible

DFT Check: Flat surfaces Longitudinal stiffeners Transverse stiffeners and girders Large brackets and primary supports Around openings Areas inaccessible by airless spray

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: The Pre-delivery (Completion) Inspection should be carried out after sea trials / ballasting whenever possible.
