Section 3 Manufacture and construction

3.1 Verification activities

3.1.1 Verification activities carried out by LR during the manufacturing and construction phases of the submarine lifecycle are at the request of either the submarine builder or the Owner of the submarine.

3.1.2 Verification activities carried out by LR during the manufacturing and construction phases of the submarine lifecycle are verification activities carried out to confirm that the construction of the submarine and the manufacturing of systems, equipment and components used in the construction of the submarine satisfy the previously approved design and the requirements within previously verified project specifications, Rules, Codes and Standards.

3.1.3 Verification activities are to be undertaken in accordance with the Product Verification Plan. LR will advise the equipment manufacturer or builder and Naval Administration where the systems, equipment and components are not in compliance with the design documentation, project specifications, Rules, Codes and Standards. The items identified are to be modified or a suitable engineering justification provided.

3.1.4 Verification activities carried out by LR during construction of the submarine, manufacturing of systems, equipment and components are based on periodical visits to the construction site or manufacturers works and as such LR’s Surveyors may not be in continual attendance. Recognising that submarine construction and systems, equipment or component manufacturing are continuous processes, the submarine builder has the overall responsibility to the Owner for ensuring and documenting that the verification requirements of the Submarine Assurance Plan have been satisfied.

3.1.5 Prior to verification, LR is to be satisfied that the capability, organisation and facilities of the submarine builder and manufacturer are such that acceptable standards can be obtained for the construction of the submarine and its systems, equipment and components. The requirements of the Product Verification Plan are to be consistent with the builder’s and manufacturer’s quality systems.

3.1.6 Prior to verification, LR is to be satisfied that the submarine builder and manufacturer have established and documented quality assurance processes for submarine construction in place which include management, change control, equipment procurement, traceability, construction, inspection and testing processes. The quality assurance processes are to describe both second-party and third-party assurance.

3.1.7 The submarine builder and manufacturer are responsible for maintaining copies of approved documentation, certificates and records, and is to make these available to LR on request.
