Abstract
Abstract A device for mooring a vessel to a mooring tower, buoy, seabed, or the like, has a device for absorbing excessive mooring forces. The vessel will normally travel a given distance when attached to the mooring tower or the like, due to forces such as waves, wind, or tide. However, when extreme conditions are encountered such that the vessel attempts to travel beyond this given distance, the device for absorbing can accommodate these excessive forces. The device for absorbing will permit the vessel to travel a distance which is greater than or equal to the given distance under these extreme conditions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A mooring device for a floating body comprising: a device anchored to the seabed, said device having at least one rigid arm pivotally connected thereto; first weight means connected to said arm for exerting a force thereon; tension means for connecting said arm to said floating body, said tension means having at least two components joined at a connection, the first component being attached to the floating body and the second component being attached to said first weight means; second weight means attached to said tension means at the connection between said at least two components for exerting a force on said tension means, said floating body having a normal mooring force exerted thereon whereby said floating body will travel a first distance determined by the force of the first weight means and if said normal mooring force is exceeded, the floating body will travel a second distance determined by the combined forces of said first and second weight means, said second distance being greater than the first distance.
Claim 2
Dependent Claim
169 words
A mooring device for a floating body comprising: a device anchored to the seabed, said device having at least one rigid arm pivotally connected thereto; first weight means connected to said arm for exerting a force thereon; tension means for connecting said arm to said floating body, said tension means having at least two components joined at a connection, the first component being attached to the floating body and the second component being attached to said first weight means; second weight means attached to said tension means at the connection between said at least two components for exerting a force on said tension means, said floating body having a normal mooring force exerted thereon whereby said floating body will travel a first distance determined by the force of the first weight means and if said normal mooring force is exceeded, the floating body will travel a second distance determined by the combined forces of said first and second weight means, said second distance being greater than the first distance.
Claim 3
Dependent Claim
36 words
The mooring device as recited in claim 1, wherein said floating body is a ship and said device anchored to the seabed is one of a mooring tower, a mooring buoy and a ship at anchor.
Claim 4
Dependent Claim
32 words
The mooring device as recited in claim 1, wherein the second weight means comprises a weight attached to the connection of the tension means by one of a cable and a chain.
Claim 5
Dependent Claim
49 words
The mooring device as recited in claim 1, wherein said second weight means comprises the floating body itself, said tension member rests against a stop provided at the level of the connection of the at least two components when the floating body fails to travel beyond said first distance.
Claim 6
Dependent Claim
34 words
The mooring device as recited in claim 1, wherein said second weight means comprises a hydraulic piston-cylinder device attached to the connection of the tension means by one of a cable and a chain.
Claim 7
Dependent Claim
33 words
The mooring device as recited in claim 1, wherein said second weight means comprises an automatic winch attached to the connection of the tension means by one of a cable and a chain.
Claim 8
Dependent Claim
34 words
The mooring device as recited in claim 1, wherein said second weight means comprises an elastic pulling component attached to the connection of the tension means by one of a cable and a chain.
Claim 9
Dependent Claim
50 words
The mooring device as recited in claim 1, wherein said second weight means is located inside the floating body at the end of one of a cable and a chain, said second weight means having a rest positioned determined by a stop against which the tension means comes to rest.
Claim 10
Dependent Claim
74 words
The mooring device as recited in claim 1, wherein said tension means has at least one more additional component, said additional component being joined to said tension means at a second connection whereby said tension means has at least three components and two connections, said mooring device further comprising additional weight means for exerting a force on said tension means, said additional weight means being attached to said tension means at the second connection.
