Abstract
Abstract In order to keep a ship in constant position when moored at a quay, one or more mooring winches are mounted fore and aft of the ship and connected to fixed points on the quay. A pillar on the quay is engaged by a forked rod pivoted at the side of the ship. Pivoting of this rod by any movement of the ship operates a control device which sets one or the other of the winch motors in operation so as to restore the ship in its original position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
In connection with a quay element and a ship element, means for keeping the position of the ship element constant with respect to the quay element during mooring, comprising at least one mooring winch fore and at least one aft of the ship carried by one of said elements, a member movably mounted on one of said elements at the side of the ship adjacent the quay for cooperation with a stationary point on the other element and responsive to relative movement between the elements, at least one program device operatively connected to said movable member and responsive to movement thereof to assume different turning positions to control the torques of the winch motors, whereby to keep the ship element in a certain position with respect to the quay element.
Claim 2
Dependent Claim
130 words
In connection with a quay element and a ship element, means for keeping the position of the ship element constant with respect to the quay element during mooring, comprising at least one mooring winch fore and at least one aft of the ship carried by one of said elements, a member movably mounted on one of said elements at the side of the ship adjacent the quay for cooperation with a stationary point on the other element and responsive to relative movement between the elements, at least one program device operatively connected to said movable member and responsive to movement thereof to assume different turning positions to control the torques of the winch motors, whereby to keep the ship element in a certain position with respect to the quay element.
Claim 3
Dependent Claim
55 words
In an arrangement according to claim 1, the program device comprise cam discs, control circuits for the winch motors, control elements in the control circuits operatively engaging said cam discs, said cam discs being connectable in different turning positions to said movable member, whereby different torque is set for the winches at different turning angles.
Claim 4
Dependent Claim
24 words
In an arrangement according to claim 1, the program device being provided with an adjusting member for the desired neutral position of the ship.
Claim 5
Dependent Claim
60 words
In an arrangement according to claim 1, comprising at least four winch motors, one pair situated fore and the other pair aft, one of the motors of each pair operating fore and the other aft, wherein when the ship moves forward the fore-operating torque is decreased and the aft-operating torque is increased, and vice versa when the ship moves backward.
Claim 6
Dependent Claim
43 words
In an arrangement according to claim 1, the movable member comprising an elongated member on the ship element cooperating with a stationary member on the quay element, whereby when the ship element moves along the quay element the program device will be turned.
