ShipRight procedures are a comprehensive system of procedures aimed at ensuring high  standards of safety, quality and reliability at the design stage and during construction. These procedures also extend, via Linked Supporting Services, to ensure that these standards are met through the operational lifetime of the ship.

Procedures considered as providing the basic level of acceptable safety to the ship, cargo and/ or crew are mandatory while those which serve to augment this are optional. Compliance with a Shipright procedure will render the vessel eligible for a ShipRight Notation and/or Descriptive Note. In cases where a procedure is applied to a vessel outside of the classification regime, a certificate of compliance may be issued if appropriate.

ShipRight procedures provide either a definitive procedural process e.g. SDA; or provide guidance and procedural information, in a less prescriptive manner, to novel or new processes e.g. WDA. They can be considered as “routes to compliance” with the relevant Rule criteria. i.e. following a ShipRight Procedure and achieving the acceptance criteria is a pre-accredited means of demonstrating satisfactory compliance.
