Abstract: Captive ship model tests are conducted to determine the hydrodynamic derivatives appearing in the maneuvering equations of motions of a ship. These hydrodynamic derivatives have an important role in maneuvering prediction of a ship at early design stages. Practically, surface ships operate at different speed conditions. Variation in vessel speed will affect the hydrodynamic derivatives and subsequently maneuvering characteristics of the ship. This paper investigates the effect of vessel speed on the derivatives and maneuvering characteristics of a ship. Captive model tests are numerically simulated in a CFD environment for a container ship at different Froude numbers to estimate the influence of Froude number on hydrodynamic derivatives and on the turning characteristics of the ship.
