I assume you refer to an FSO or FPSO. If it is the case, then it is the test running of a new or existing vessel plant, utilities and equipment to demonstrate completed systems or sub-systems are safe and operable. Unless otherwise specified, this scope is typically defined the ‘Certifying Authority’ (e.g. ABS, DNV, etc.), and carried out by the supplier or conversion shipyard, witnessed by the Project and approved by the ‘Certifying Authority’. Typical ‘Class Survey’ vessel system scope: Testing of existing power generation, operation of engine room utilities, operation of cargo handling systems, and operation of boiler systems. A comprehensive database of all class related activities is prepared and maintained by the project quality manager. The project quality manager is responsible for ensuring the activities within the database are progressively completed and signed off by the certifying authority, in accordance with the project schedule. All test results are recorded and stored in the Completion Database.
