scope:

This CP gives a description of the procedures and requirements related to documentation, design and type testing applicable for TA of elastic (torsional) couplings for torque transmission in propulsion or auxiliary plants.

This CP does not set the design requirements to the elastic (torsional) couplings used for torque transmission in propulsion or auxiliary plants. TA is based on compliance with design requirements given in the DNV GL rules and/or other regulations and standards. The CP describes the documentation requirements as well as further inspections / tests in order to verify compliance of the specimens for design features, strength and dynamic properties, in order to obtain a TA certificate for the equipment. This includes, where relevant, technical requirements for how the type tests shall be performed.
