METHOD OF SHIP CONTROL IN MOORING TO PARTNER SHIPBOARD Russian patent published in 2013 - IPC B63H25/00 

FIELD: transport.

SUBSTANCE: invention relates to water transport, particularly, to ship maneuvering in mooring to partner shipboard. Approach of ships is carried out in three stages whereat preset points of the plane are used foe each said stage. At first stage, ship to be moored comes to the first preset point and, at second stage, to the second preset point. At third stage, ship to be moored approaches partner ship to distance that allows lashing working lines. For this, preset current position of approach path, A'_nB'_n line, is gradually displaced parallel with partner ship centerline plane toward said partner ship at speed not exceeding tolerable crosswise speed υ_t of mooring ship toward partner ship. Note here that, in parallel displacement of line A'_nB'_n , current position of points A'_n and B'_n of line A'_nB'_n are continuously calculated depending upon distance h between boards of two ships. Note here that h is gradually decrease by law dh/dt=f(υ_t, h, h₀,…).

EFFECT: safe mooring.
