Abstract

Abstract The buoy (3) and rigid arm (15) are free to rotate about the vertical axis (A-A) of the buoy. The rigid arm (15) is connected to the single point mooring buoy by a hinge arrangement (9) and an axial rotational connection (10) to allow for independent pitch and roll motions of the buoy in relation to the rigid arm. The vessel (1) is connected to the rigid arm by two tension members (6,7), which could be chains, cables or bars. The rigid arm is ballasted (13,14) at the vessel end. In addition, the vessel and the single point mooring buoy may be connected using a conventional hawser (18). The weight of the rigid arm and its ballast, and the loading on the tension members, combine to produce a restoring force and moment which prevent the vessel from riding up to the buoy or jack-knifing of the assembly when the rigid arm moves out of line with the centre line of the vessel.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 117 words
A buoy for mooring a vessel floating on the surface of a body of water, said buoy anchored to the floor of said body of water by means of one or more anchor points and anchor chains, said vessel being connected to said buoy by means of a rigid arm, said rigid arm being fitted to one end in either a fixed or a pivotable manner to said buoy, said rigid arm being free to rotate about the vertical axis of said buoy, said rigid arm being fitted to said vessel via two pivotable tension members which are attached to the rigid arm at the vessel end, said pivotable tension members being separated by a certain distance.
Claim 2
Dependent Claim 117 words
A buoy for mooring a vessel floating on the surface of a body of water, said buoy anchored to the floor of said body of water by means of one or more anchor points and anchor chains, said vessel being connected to said buoy by means of a rigid arm, said rigid arm being fitted to one end in either a fixed or a pivotable manner to said buoy, said rigid arm being free to rotate about the vertical axis of said buoy, said rigid arm being fitted to said vessel via two pivotable tension members which are attached to the rigid arm at the vessel end, said pivotable tension members being separated by a certain distance.
Claim 3
Dependent Claim 19 words
The buoy of claim 1, and furtlez comprising an axia- rotational connection which is located in the rigid arm.
Claim 4
Dependent Claim 14 words
The buoy of claim 1 or 2, in which the rigid arm is Y-shaped.
Claim 5
Dependent Claim 18 words
The buoy of claim 1 and/or claim 2, and further comprising ballast weight(s) located in the rigid arm.
Claim 6
Dependent Claim 30 words
The buoy of any of claims 1 to 4, wherein the tension members consist of chains or cables which can be suspended through the anchor chain hawses of the vessel.
Claim 7
Dependent Claim 20 words
The buoy of any of claims 1 to 5, and further comprising hinges between the buoy and the rigid arm.
Claim 8
Dependent Claim 19 words
