What is included in the inspection and testing stage of ship construction?

The inspection and testing stage of ship construction is a critical phase that involves evaluating the vessel's performance, safety, and compliance before it is delivered for operation. Builder and sea trials are fundamental components of this stage, as they assess how the ship performs under various conditions in the water. This includes testing key systems such as propulsion, navigation, and safety equipment to ensure everything functions as intended.

During builder trials, the ship is typically tested in controlled conditions to verify construction quality and workmanship. Sea trials then put the ship through real-world scenarios, addressing factors like speed, maneuverability, and stability. Successful completion of these trials is essential to confirm that the ship meets regulatory standards and design specifications.

In contrast, other options like contract signing, building materials acquisition, and launch ceremonies are important steps in the overall construction process but do not fall under the inspection and testing phase. They involve planning, preparation, and formalities rather than the direct evaluation of the ship's construction and performance.
