5.2.4 Where an *IWS (In-Water Survey) notation is to be assigned (see Pt 1, Ch 2, 2.3 Class notations (hull) 2.3.11), plans and information covering the following items are to be submitted:

• Details showing how rudder pintle and bush clearances are to be measured and how the security of the pintles in their sockets is to be verified with the vessel afloat.
• Details showing how for water lubricated bearings, sternbush clearances are to be measured with the vessel afloat.
• Details of high resistance paint, for information only.

5.2.5 Where it is intended to exchange ballast water at sea resulting in the partial filling of the ballast spaces, the scantlings and structural arrangements of the tank boundaries are to be capable of withstanding the loads imposed by the movement of the ballast water in those spaces. The magnitude of the predicated loadings, together with the scantling calculations, may require to be submitted.

5.2.6 Ships that are required to comply with SOLAS Regulation 3-6 in chapter II-1 for ‘Access to and within spaces in the cargo area of oil tankers and bulk carriers’ are to supply information showing attachment of the access arrangements to the ship structure. This is to include necessary strength calculations, local detail and any reinforcements.

5.2.7 Ships that are required to comply with the Performance Standards for Protective Coatings of SOLAS Regulation 3-2 - Protective coatings of dedicated seawater ballast tanks in all types of ships and double-side skin spaces of bulk carriers are to submit information on the coating specification agreed by the shipyard, the ship owner and the manufacturer, including the coating system selection, surface preparation and coating application and inspection procedure. Corrosion prevention arrangements and coating system specifications are to comply with Ch 15 Corrosion Prevention of the Rules for Materials.

5.3.1 A Ship Construction File is to be provided on board of the ship containing information to facilitate inspection/survey, repair and maintenance. As a minimum it is to include the following documentation and plans:

1. Copies of approved as-built plans, including the main scantling plans are to be placed on board the ship. These plans are to indicate, as applicable, the disposition and grades (other than Grade A) of hull structural steel, the extent and location of higher tensile steel together with details of specification and mechanical properties, location of butts and seams, cross-section details and locations of all partial and full penetration welds, areas identified for close attention and rudders, wastage allowances and any recommendations for welding, working and treatment of these steels.
2. Similar information is to be provided on board when aluminium alloy or other materials are used in the hull construction.
3. Copies of certificates of forgings and castings welded into the hull.
4. Details of equipment forming part of the watertight and weather tight integrity of the ship.
5. Electrical cables schedule of watertight penetrations (e.g. cable transit seal systems register).
6. The approved tank testing plan including details of the test requirements.
7. Docking plan and details of all penetrations normally examined at dry-docking.
8. Ship structure access manual, as applicable.
9. A copy of the final Loading Manual, when approved, and details of the loadings applicable to approved decks, hatch covers and inner bottom.
10. Operations and maintenance manuals required for classification (e.g. hatch cover and coamings, shell doors and container securing arrangements).
11. Details of any corrosion prevention systems applied or fitted.
12. For ships that are required to comply with IMO Performance Standard for Protective Coatings, a copy of the Coating Technical File (CTF), see Ch 15 Corrosion Prevention of the Rules for the Manufacture, Testing and Certification of Materials, July 2022.
13. Where an *IWS (In-water Survey) notation is to be assigned, approved plans and information covering the items detailed in Pt 3, Ch 1, 5.2 Plans and supporting calculations 5.2.4 .
14. Where the ShipRight notation CM is to be assigned, the approved Construction Monitoring Plan (CMP), as detailed in the ShipRight Construction Monitoring Procedures.
