Abstract
Abstract Mooring apparatus for ships, particularly tankers comprises a cable which is retractable into a column which is pivotally connected to a base anchored to the sea bed. The cable is retracted by a counterweight or similar device, is withdrawn from the column by traction exerted by the ship being moored, and is arrested by engagement of the counterweight against an upper stop associated with the column.

Total Claims: 9
Claim 1
Independent Claim
137 words
Apparatus for mooring a ship comprising an elongate column, means for buoying said column in an upright manner in water, means for pivotally connecting the lower end of said column to a base anchored to a sea bed, a mooring cable having a first end for attaching to a ship to be moored and a second end attached to a counterweight moveable lengthwise of said column to permit extraction and retraction of said mooring cable out of and into said column, means for guiding the motion of said counterweight and cable lengthwise of said column and stop means for stopping the upward motion of said counterweight, said cable being arranged to be extracted from said column for the purpose of mooring a ship by traction applied by the ship to raise the counterweight against said stop means.
Claim 2
Dependent Claim
137 words
Apparatus for mooring a ship comprising an elongate column, means for buoying said column in an upright manner in water, means for pivotally connecting the lower end of said column to a base anchored to a sea bed, a mooring cable having a first end for attaching to a ship to be moored and a second end attached to a counterweight moveable lengthwise of said column to permit extraction and retraction of said mooring cable out of and into said column, means for guiding the motion of said counterweight and cable lengthwise of said column and stop means for stopping the upward motion of said counterweight, said cable being arranged to be extracted from said column for the purpose of mooring a ship by traction applied by the ship to raise the counterweight against said stop means.
Claim 3
Dependent Claim
65 words
Apparatus according to claim 1 further including a boom mounted adjacent the upper end of said column, a flexible hose carried by said boom, means for placing a free end of said flexible hose in fluid communication with a fluid outlet on a ship, and means connecting said free end of said flexible hose to said mooring cable whereby the flexible hose is moveable therewith.
Claim 4
Dependent Claim
70 words
Apparatus according to claim 2 further including a rope attached at one end to the outer end of said boom and at the other end to said cable, a float secured to said rope intermediate its ends and positioned to float on the surface of the water in which the column is located, said rope forming a loop to facilitate picking up of said mooring cable for mooring a ship.
Claim 5
Dependent Claim
51 words
Apparatus according to claim 2 including means positioning said boom outwardly of said column, and means for guiding said cable outwardly of said column to a ship being moored at a fixed, predetermined angle, in plan view, with respect to said boom to prevent entangling of said hose and mooring cable.
Claim 6
Dependent Claim
27 words
Apparatus according to claim 4 further including shock absorbing means adjacent said stop means for absorbing shock of contact between a rising counterweight and said stop means.
Claim 7
Dependent Claim
