METHOD OF SHIP CONTROL WHEN SHE IS MOORING TO BOARD OF PARTNER SHIP Russian patent published in 2011 - IPC B63H25/00 

FIELD: transport.

SUBSTANCE: invention relates to water transport, specifically to mooring ship motion control when she is executing mooring operation to partner ship. Current position of approach path is determined as straight line passing through two points in the plane one of which is the center of gravity of mooring ship and the second is target point. Control method consists in that approach is executed in two steps to ensure safety of mooring operation, herewith, in each step of approach, peculiar target point in the plane is used. Current position of target points in the plane at any given moment is calculated using values of current coordinates of fore and aft points of partner ship, given distance between boards of mooring ships, target position of mooring ship relative to partner ship in mooring final stage, and current value of mooring ship braking path length necessary for its transition from original speed to the speed equal to partner ship speed in specific conditions. Length of braking path is determined depending on ship loading and ambient environment.

EFFECT: invention provides secure execution of mooring operation of mooring ship to partner ship.
