Analytical calculation of the vessel maneuver «sideways movement» parameters

A boatmaster must be well aware of the manoeuvrability of his vessel as well as the ability of the ship's controls to perform a manoeuvre. In the "Information" on maneuvering parameters, which is available on the ship, there is no data on the performance of such an important maneuver as "sideways movement," which is often used in the performance of mooring maneuvers in a cramped water area. In the work, having made some assumptions, the solution of the system of equations of movement of the vessel in relation to the considered maneuver is given. The author has obtained analytical expressions for calculating the speed and distance traveled by the vessel according to the time of the "acceleration" maneuver, inertia movement and active suppression of the speed of movement. Using the obtained expressions, the parameters of the "sideways movement" of the motor ship of project 507 were calculated. Graphs of the dependence of the speed and distance traveled by the vessel on the maneuver time are given.
