A '''ship model basin''' is a [[dock (maritime)|basin]] or [[water tank|tank]] used to carry out [[hydrodynamics|hydrodynamic]] tests with [[ship model]]s, for the purpose of designing a new (full sized) ship, or refining the design of a ship to improve the ship's performance at sea. It can also refer to the organization (often a company) that owns and operates such a facility.

An engineering firm acts as a contractor to the relevant [[shipyard]]s, and provides hydrodynamic model tests and numerical calculations to support the design and development of ships and offshore structures.
