COMPUTING INTERACTION FORCES AND MOMENTS ON A SHIP IN RESTRICTED WATERWAYS

This paper describes investigations of the development of unsteady interaction forces as a slow-moving vessel proceeds near a vertical-sided boundary of an object or through a narrow channel. Slender body theory with a rigid free-surface assumption was used to reduce the problem to that of the unsteady motion of an airfoil near irregular boundaries. Yaw and sway were predicted using the perturbation method. Interaction effects were studied in relation to variations in the geometrical parameters of the waterway boundaries and in the distance separating the vessel and the obstacle. Five types of waterway boundaries were used to apply the results: a vertical causeway opening, a wedge-shaped obstacle, a circular cylinder, a section of a hyperbolically shaped channel, and a bank with a semicircular mound.
