Section 1 General

1.1 The applicable regulations

1.1.1 Lloyd’s Register’s verification requirements and procedures for new construction have been devised using the regulations detailed by the documents listed below, collectively referred to as PSPC-WBT (Performance Standard for Protective Coatings for Dedicated Seawater Ballast Tanks in All Types of Ships and Double-side Skin Spaces of Bulk Carriers) and PSPC-COT (Performance Standard for Protective Coatings for Cargo Oil Tanks of Crude Oil Tankers) in this document. The related standards and documents for reference refer to Figure 1.1.1 Documents for PSPC-WBT and Figure 1.1.2 Documents for PSPC-COT.

Figure 1.1.1 Documents for PSPC-WBT

Figure 1.1.2 Documents for PSPC-COT

1.1.2 MSC.215(82) refers to Performance Standard for Protective Coatings for Dedicated Seawater Ballast Tanks in All Types of Ships and Double-side Skin Spaces of Bulk Carriers.

1.1.3 UI SC223 is an IACS Unified Interpretation for Application of SOLAS Regulation II-1/3-2 Performance Standard for Protective Coatings (PSPC) for Dedicated Seawater Ballast Tanks in All Types of Ships and Double-side Skin Spaces of Bulk Carriers, adopted by Resolution MSC.215(82). It makes all footnoted standards in MSC.215(82) mandatory.

1.1.4 UR Z17 is an IACS Unified Requirement for Procedural Requirements for Service Suppliers. It provides some requirements for auditing coating test laboratories.

1.1.5 Rec.101 refers to IACS Model Report for IMO Resolution MSC.215(82) Annex 1 ‘Test Procedures for Coating Qualification’.

1.1.6 Rec.102 refers to IACS Model Report for IMO Resolution MSC.215(82) Annex 1 ‘Test Procedures for Coating Qualification’, Section 1.7 – Crossover Test.

1.1.7 Rec. 87 refers to IACS Recommendation 87 – Guidelines for Coating Maintenance & Repairs for Ballast Tanks and Combined Cargo/Ballast Tanks on Oil Tankers.

1.1.8 MSC.1/Cir.1330 refers to IMO Guidelines for Maintenance and Repair of Protective Coatings and focusses on dedicated seawater ballast tanks of all types of ships and double-side skin spaces of bulk carriers.

1.1.9 MSC.288(87) refers to Performance Standard for Protective Coatings for Cargo Oil Tanks of Crude Oil Tankers.

1.1.10 UI SC259 is an IACS Unified Interpretation for Application of SOLAS Regulation II-1/3-11 Performance Standard for Protective Coatings for Cargo Oil Tanks of Crude Oil Tankers (PSPC-COT), adopted by Resolution MSC.288(87). It makes all footnoted standards in MSC.288(87) mandatory.

1.1.11 MSC.1/Cir.1399 refers to IMO Guidelines on Procedures for In-service Maintenance and Repair of Coating Systems for Cargo Oil Tanks of Crude Oil Tankers.

1.2 Tripartite Agreement (TPA)

1.2.1 A TPA is an inspection agreement between shipyard, shipowner and coating manufacturer.

1.2.2 It is anticipated that a TPA will be completed and form the basis of the verification guidelines. This should include, but not be limited to, the below listed items:

  • IMO PSPC applied area, which includes PSPC applied tanks/spaces and relevant drawings.
  • English to be used for documentation. Where documents are written in two languages, there could be a difference between the two languages and the Tripartite Agreement shall specify that English will prevail.
  • The selected coating system and shop primer. Winter grade coatings should be specified if they are used.
  • Appointment of the Coating Inspector(s).
  • Assistants to the Coating Inspector(s).
  • Copy of certificates of the Coating Inspector(s).
  • Quality control process including inspection items, who will carry out the inspection and inspection standards.
  • Detailed requirements of coating application and inspection, including surface preparation and coating application requirements for both hull structure and out-fittings, reference standards, inspection notice, coating log forms.
  • Settlement of disputes.
  • Non-conformity report issuing and closing.
  • Health and safety.
1.2.3 To facilitate the Tripartite Agreement, the following from the Coating Technical File (CTF) shall be available:
  • Copy of Type Approval Certificates for main coatings and shop primer. The weldable certificate of the shop primer shall also be provided. And if winter grade main coatings are used, their Type Approval Certificate shall also be provided.
  • Copy of Product Technical Data Sheet (PTDS) for main coatings and shop primer. Some manufacturers have an application procedure which shall also be provided.
  • Copy of Safety Data Sheet (SDS) for main coatings and shop primer.
  • Procedure for in-service maintenance and repair of coating system, which is prepared in compliance with MSC.Circ.1330 or MSC.Circ.1399 by the coating manufacturer.

1.2.4 The Lloyd’s Register Surveyors may, if so required, participate in the agreement process.

1.3 The verification stages

1.3.1 The Lloyd’s Register verification will be carried out by Lloyd’s Register Surveyors and includes the PSPC-WBT and PSPC-COT verification process.

1.3.2 The Lloyd’s Register new building verification process for Surveyors can be broken into three stages:
  1. Before coating application is started;
  2. During coating application;
  3. After coating completion and prior to ship delivery.

1.3.3 Any deviation should be raised with the shipyard, or the Approved Inspector, as deemed appropriate by LR. In the event of corrective action, the Certificate of Class is not to be issued until all corrective actions have been closed out.
