## Abstract

The invention relates to a mooring arrangement (2, 2′) for a floating device (1, 2) comprising a band (5) and a drum (3) adapted to pay out and pull in the band (5). The invention being distinctive in that the mooring arrangement (2, 2 further comprising a band guide (14, 15,22), said band (5) is extending from the drum (3) via the band guide (14, 15, 22) and is adapted to be coupled to an anchoring arrangement (13), said band said band guide (4, 15, 22) being configured to tilt about an articulation axis (A, B) being parallel with a longitudinal axis of the part of the band (5a) situated between the drum (3) and the band guide (14, 15, 22) in order to position the band (5) to compensate for movement in the floating device (1,12, 12′) and thus reduce the wear in the band (5).

## Claims

### Claim 1

A mooring arrangement for a floating device comprising a band adapted to be connected in one end to a drum arranged on the floating device, the drum being configured to pay out and pull in the band when the floating device is exposed to motion by current, wind or waves, the band is adapted to be coupled to an anchoring arrangement at the opposite end wherein the mooring arrangement further comprising a band guide, the band is extending from the drum via the band guide towards the anchoring arrangement, the band guide being pivotable coupled to a base part arranged on the floating device, the band guide comprising a first and a second pulley arranged in series in the longitudinal direction of the band guide, the first and second pulley having a respective winch portion adapted to receive the band, and flanges arranged at both sides of the winch portion, the band guide being configured to pivot about an articulation axis being a tangential line to the first pulley and also extending through a longitudinal axis (B) of the part of the band situated between the drum and the band guide in order to make sure that the band is rolled straight over the drum to minimize the wear in the band caused by movement of the floating device.

### Claim 2 (depends on 1)

The mooring arrangement according to claim 1, wherein the base part is a frame having two legs adapted to support the band guide on opposite sides.

### Claim 3 (depends on 2)

The mooring arrangement according to claim 2, wherein the first pulley and the second pulley are arranged in a same housing structure.

### Claim 4 (depends on 1)

The mooring arrangement according to claim 1, wherein the mooring arrangement having a sensor/load cell arrangement arranged between the winch portion of the pulley structure and the pulley flanges to measure contact force between the flanges and the side of the band.

### Claim 5 (depends on 1)

The mooring arrangement according to claim 1, wherein the height of the flanges above the winch portion is at least the thickness of the band.

### Claim 6 (depends on 1)

The mooring arrangement according to claim 1, wherein the mooring arrangement further comprising a band end fitting coupling the mooring arrangement to the anchoring arrangement.

### Claim 7 (depends on 6)

The mooring arrangement according to claim 6, wherein the band end fitting having a bend constrainer arranged on both sides of the band.

### Claim 8 (depends on 6)

The mooring arrangement according to claim 6, wherein the band end fitting comprises a float.

### Claim 9 (depends on 6)

The mooring arrangement according to claim 6, wherein the mooring arrangement comprising a load cell arranged between the band end fitting and the anchoring arrangement.

### Claim 10 (depends on 1)

A floating device comprising at least one mooring arrangement according to claim 1.
