Scale model a hydrodynamic test to predict full size behaviour
Model of Emma Mærsk undergoing testing in a ship model basin
In marine engineering, a ship motion test is hydrodynamic test performed with ship models for the purpose of designing a new (full sized) ship, or refining the design of a ship to improve its performance at sea.[1] Tests are carried out in a ship model basin or "towing tank".[2] There are various types of test: the model may be towed along a straight line or circular path, and may be subjected to oscillations. Forces acting on the vessel are measured using a dynamometer.[2] The tests may be evaluating the overall design, or focusing on the characteristics of a propeller.[2]
