INTERACTION EFFECTS OF SHIPS OPERATING PROXIMITY IN DEEP AND SHALLOW WATER
This paper introduces a mathematical model for use in the effective simulation of ship motions when ships operate in close proximity to one another or in a canal. The model calculates the longitudinal and lateral interaction forces and the interaction yaw moment arising from both steady effects (due to relative longitudinal, lateral and heading orientation) and unsteady effects (due to ships' velocities and accelerations, both linear and angular) and includes the effects of shallow water. The interaction force model was combined with the ordinary manoeuvring mathematical model to provide a trajectory model and computer program for use in the simulation of ships manoeuvring in proximity. Examples are given of the use of the trajectory model in the simulation of underway replenishment operations. Order from: BSRA as No. 46,662.
