SHIP MOORING METHOD Russian patent published in 2008 - IPC B63H25/04 

FIELD: transportation.

SUBSTANCE: method uses a rudder drive, a transverse bow propeller and the ship screw propeller rpm controller. Mooring is effected in two stages using preset point B of the first stage termination and the second stage beginning. The signal indicating the moment the ship comes into point B is generated proceeding from the equality of the route angle vector length to the preset value. The course control is programmable and uses a rudder control drive. Track angle control uses a bow maneuvering propulsion de maneuvering propulsion device at the first mooring stage in compliance with the preset track angle signal formed depending upon the preset track angle vector length, while at the second mooring stage, the ship screw propeller rpm controller is used. At the first stage, the screw propeller rpm controller is used to control the ship speed in varying depending upon the track angle preset vector length.

EFFECT: automatic control of the ship mooring motions.
