Abstract
Abstract The present invention relates to a mooring system comprising a floating device with or without storage capacity and to which another ship can be moored which floating device has been connected with an anchor or the like in a manner such that in case of displacements of the floating device a return force is generated from structure which is under vertical tension, the improvement being that the structure which generates the return force is placed inside a space within the hull of the floating device and which is protected with respect to the surroundings.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
148 words
In a mooring device comprising a tanker floating on the surface of a body of water and having an arm pivotably connected to the vessel at one point on the arm, a tension-resistant connecting member connected to said arm at a second point spaced from said one point and extending toward the bottom of the body of water and connected to a bottom anchor, and a body having positive buoyancy in water and whose buoyancy exerts an upward force to maintain said connecting member under tension; the improvement in which the ship has a hull that has interior side walls that laterally surround a protected space that contains a liquid in which said body is at least partially submerged and has positive buoyancy, said body having large clearance with respect to said side walls, said protected space extending above and below the surface of said body of water.
Claim 2
Dependent Claim
148 words
In a mooring device comprising a tanker floating on the surface of a body of water and having an arm pivotably connected to the vessel at one point on the arm, a tension-resistant connecting member connected to said arm at a second point spaced from said one point and extending toward the bottom of the body of water and connected to a bottom anchor, and a body having positive buoyancy in water and whose buoyancy exerts an upward force to maintain said connecting member under tension; the improvement in which the ship has a hull that has interior side walls that laterally surround a protected space that contains a liquid in which said body is at least partially submerged and has positive buoyancy, said body having large clearance with respect to said side walls, said protected space extending above and below the surface of said body of water.
Claim 3
Dependent Claim
17 words
Mooring device as claimed in claim 1, in which the protected space is closed at the underside.
Claim 4
Dependent Claim
31 words
Mooring device as claimed in claim 1, in which in said space there is a liquid having a specific mass which is different from the specific mass of the outside water.
Claim 5
Dependent Claim
31 words
Mooring device as claimed in claim 1, in which there is water in the protected space the level of which is higher or lower than the level of the outside water.
Claim 6
Dependent Claim
40 words
Mooring device as claimed in claim 1, in which the arm and the body with buoyancy are placed inside the protected space and the tensionresistant connection with the bottom anchor extends downwardly through the open underside of the protected space.
Claim 7
Dependent Claim
41 words
Mooring device as claimed in 1, in which, the body with buoyancy has a shape such that the liquid displacement increases progressively or decreases respectively upon emersion of the buoyant body or lifting out of the liquid respectively of the body.
Claim 8
Dependent Claim
18 words
Mooring device as claimed in claim 1, in which, the body with buoyancy comprises a plurality of bodies.
Claim 9
Dependent Claim
16 words
Mooring device as claimed in claim 7, in which said bodies are present in separate spaces.
Claim 10
Dependent Claim
25 words
Mooring device as claimed in claim 1, in which, means are provided which dampen the movement of the body with buoyancy in the said space.
Claim 11
Dependent Claim
23 words
Mooring device as claimed in claim 1, in which, the pivotable connection of the arm with tanker is on an outrigger extending outboard.
Claim 12
Dependent Claim
53 words
Mooring device as claimed in claim 1 in which the tanker by means of said arm pivotably connected with it about a horizontal shaft has been connected with a buoy which is anchored by means of anchoring chains, and in which the arm and the buoy both are present inside the protected space.
Claim 13
Dependent Claim
73 words
Mooring device as claimed in claim 1 in which the tanker, by means of said arm which is pivotably connected about a horizontal shaft with the tanker, is connected to a column having buoyancy in at least the upper part and connected pivotably to a bottom anchor, and in which the arm is inside the protected space and the column extends upwardly into said space through the open underside of the said space.
Claim 14
Dependent Claim
19 words
A mooring device as claimed in claim 1, said protected space being downwardly open to said body of water.
Claim 15
Dependent Claim
18 words
A mooring device as claimed in claim 13, said tension-resistant connecting member extending up into said protected space.
