Acceptance tests performed on ship equipment and systems, in the presence of an Owner’s supervisor and/or a class surveyor to demonstrate suitable performance. Dock tests can start only when installation of equipment and systems subject to testing is totally finished and necessary tightness tests carried out. The scope of the dock tests is to be specified in the Dock Test Program that should be prepared by the Shipyard and submitted to Owners approval 2 months before the beginning dock tests. To avoid delay and misunderstanding during tests, the Dock Test Program is to include detailed test procedures prepared according to recommendations and procedures described in maker manuals.
