Abstract
Abstract An offshore vessel mooring system in which a one-point mooring buoy has attached thereto a mooring cable and floating hose which are maintained in an extended condition along the surface of the water by a floating propulsion unit attached to the free ends of the mooring cable and floating hose to thereby facilitate the mooring of a vessel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
An offshore vessel mooring system for loading or unloading a fluid medium to or from said vessel, said system comprising: a one-point mooring buoy positioned on the surface of a body of water; anchoring means attached to said buoy for maintaining said buoy at an offshore location; mooring cable means having one end attached to said buoy; floating hose means having one end operatively connected to said buoy; a floating body operatively connected to the other ends of said mooring cable means and said floating hose means; and, propulsion means carried by said floating body; said propulsion means including a motor and being adapted to move said floating body away from said mooring buoy to thereby maintain said mooring cable means and said floating hose means in a permanently radially stretched condition along the surface of the body of water.
Claim 2
Dependent Claim
140 words
An offshore vessel mooring system for loading or unloading a fluid medium to or from said vessel, said system comprising: a one-point mooring buoy positioned on the surface of a body of water; anchoring means attached to said buoy for maintaining said buoy at an offshore location; mooring cable means having one end attached to said buoy; floating hose means having one end operatively connected to said buoy; a floating body operatively connected to the other ends of said mooring cable means and said floating hose means; and, propulsion means carried by said floating body; said propulsion means including a motor and being adapted to move said floating body away from said mooring buoy to thereby maintain said mooring cable means and said floating hose means in a permanently radially stretched condition along the surface of the body of water.
Claim 3
Dependent Claim
53 words
A mooring system as defined in claim 1 wherein said mooring cable means is operatively connected to said floating body by constant tension means prior to the engagement of said mooring means by a vessel, said constant tension means maintaining a constant tension on said mooring cable means indepenDent of said propulsion means.
Claim 4
Dependent Claim
213 words
An offshore vessel mooring system for loading or unloading a fluid medium to or from said vessel, said system comprising: a one-point mooring buoy positioned on the surface of a body of water; anchoring means attached to said buoy for maintaining said buoy at an offshore location; mooring cable means having one end attached to said buoy; floating hose means having one end operatively connected to said buoy; a floating body operatively connected to the other ends of said mooring cable means and said floating hose means; propulsion means carried by said floating body; said propulsion means being adapted to move said floating body away from said mooring buoy to thereby maintain said mooring cable means and said floating hose means in a permanently radially stretched condition along the surface of the body of water; said mooring cable means being operatively connected to said floating body by constant tension means prior to the engagement of said mooring means by a vessel, said constant tension means maintaining a constant tension on said mooring cable means independent of said propulsion means; and said constant tension means comprising a weight attached to said other end of sad mooring cable means and pulley means carried by said floating body and adapted to engage said mooring cable means.
Claim 5
Dependent Claim
213 words
An offshore vessel mooring system for loading or unloading a fluid medium to or from said vessel, said system comprising: a one-point mooring buoy positioned on the surface of a body of water; anchoring means attached to said buoy for maintaining said buoy at an offshore location; mooring cable means having one end attached to said buoy; floating hose means having one end operatively connected to said buoy; a floating body operatively connected to the other ends of said mooring cable means and said floating hose means; propulsion means carried by said floating body; said propulsion means being adapted to move said floating body away from said mooring buoy to thereby maintain said mooring cable means and said floating hose means in a permanently radially stretched condition along the surface of the body of water; said mooring cable means being operatively connected to said floating body by constant tension means prior to the engagement of said mooring means by a vessel, said constant tension means maintaining a constant tension on said mooring cable means independent of said propulsion means; and said constant tension means comprising a weight attached to said other end of sad mooring cable means and pulley means carried by said floating body and adapted to engage said mooring cable means.
Claim 6
Dependent Claim
22 words
A mooring system as defined in claim 3 including vertically extending tube means carried by said floating body for guiding said weight.
Claim 7
Dependent Claim
22 words
A mooring system as defined in claim 4 wherein said pulley means is carried by the upper end of said tube means.
Claim 8
Dependent Claim
21 words
A mooring system as defined in claim 5 wherein said propulsion means comprise an internal combustion engine and a screw propeller.
Claim 9
Dependent Claim
44 words
A mooring system as defined in claim 6 including: ballast chamber means carried by said floating body; and, pump means in communication with said ballast chamber means and said body of water to vary the amount of ballast water in said ballast chamber means.
