Abstract
Abstract The invention relates to a system for mooring a floating contrivance such as a ship, the system comprises at least one lever arm pivotally connected to the ship on the one hand and to a mooring device on the other hand, and a counterweight directly secured to the lever arm at a portion thereof located outside of the ship and always submerged in the sea water.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A system for mooring a ship to a mooring device, the latter being constituted by a column on the top end of which a mooring head is rotatably mounted in coaxial relation thereto, comprising a pair of lever arm sets, each lever arm set being independent from and unconnected to the other lever arm set and including a first lever arm pivotally connected directly to the ship and a second lever arm pivotally connected to said rotatably mounted mooring head with said first and second lever arms being pivotally connected to each other, and wherein each of said lever arm sets is located on a respective side of the longitudinal axis of the ship; and first and second counterweights, each counterweight being secured to one of said first and second lever arms of a respective lever arm set at an end region thereof adjacent to the other lever arm, so that said counterweights are continuously submerged in the sea water to create a stable equilibrium position with a self-acting biasing force urging the system to the equilibrium position.
Claim 2
Independent Claim
178 words
A system for mooring a ship to a mooring device, the latter being constituted by a column on the top end of which a mooring head is rotatably mounted in coaxial relation thereto, comprising a pair of lever arm sets, each lever arm set being independent from and unconnected to the other lever arm set and including a first lever arm pivotally connected directly to the ship and a second lever arm pivotally connected to said rotatably mounted mooring head with said first and second lever arms being pivotally connected to each other, and wherein each of said lever arm sets is located on a respective side of the longitudinal axis of the ship; and first and second counterweights, each counterweight being secured to one of said first and second lever arms of a respective lever arm set at an end region thereof adjacent to the other lever arm, so that said counterweights are continuously submerged in the sea water to create a stable equilibrium position with a self-acting biasing force urging the system to the equilibrium position.
Claim 3
Dependent Claim
20 words
A mooring system according to claim 1, wherein said counterweight-supporting lever arm is the arm pivotally connected to the ship.
Claim 4
Dependent Claim
24 words
A mooring system according to claim 1, wherein the said lever arm supporting the counterweight is the arm pivotally connected to the mooring device.
Claim 5
Dependent Claim
15 words
A mooring system according to claim 1, wherein said column is a fully submerged column.
Claim 6
Dependent Claim
37 words
A mooring system according to claim 1, wherein are provided at least one flexible hose pipe and at least one rotary joint for providing at least one fluid flow-conveying connection between said mooring device and said ship.
Claim 7
Dependent Claim
14 words
A mooring system according to claim 1, wherein said column is an emergent column.
