Section 3 Attachment Points

Parent topic: Chapter 1 Exostructure

3.1 General

3.1.1 Where applicable each submersible craft shall be provided with lifting point(s) and a towing point.

The lifting point shall be so designed and arranged that it will be capable of withstanding the forces associated with launching and recovering the submersible craft. In designing the lifting attachment due regard should be paid to the worst anticipated operating conditions and the dynamic forces of the launch and recovery operation in association with any compatible lifting system and support craft. Suitable tests should be applied to attachment points to simulate dynamic forces. Test loading is to be not less than that laid down for classed launch and recovery systems (see Pt 5, Ch 7, 1.4 Periodic surveys 1.4.1).

3.1.2 The lifting point should be of sufficient strength to allow in an emergency situation the craft to be raised to the surface with any compartment flooded.

3.1.3 The towing point shall be so designed and attached that it shall be capable of withstanding the forces associated with towing the submersible craft at its maximum towing speed having, regard to the worst anticipated operating conditions and the dynamic forces arising there from.

3.1.4 In craft which use towing as the sole means of propulsion arrangements must be provided to permit the towing cable to be severed or jettisoned in an emergency.

3.1.5 The structural analysis of the pressure hull and the exostructure shall take account of any loads arising from the use of the lifting and towing points having regard to any dynamic forces which may occur and the worst anticipated operating or emergency conditions.
