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).

Marine geophysical damper system. At least some of the example embodiments are methods of manufacturing a geophysical data product including obtaining geophysical data by a sensor streamer; and recording the geophysical data on a tangible computer-readable medium. The obtaining may include: towing a sensor streamer and a dilt buoy, the dilt buoy coupled to a proximal end of the sensor streamer by a line, the sensor streamer is submerged in a body of water and the dilt buoy is disposed at the surface the body of water; and during the towing measuring movement of the dilt buoy caused by surface wave action; and selectively damping relative movement between the dilt buoy and the sensor streamer, the relative movement caused by the surface wave action, and the selectively damping by a damper associated with the line.

A method for operating a winch and a winch comprising a winch drum for spooling a spoolable medium for mooring a vessel, and a winch drive configured to drive the winch drum, wherein, during the driving of the winch drum, at least when a monitored tension of the spoolable medium is between a second upper tension threshold and a second lower tension threshold, an absolute value of the driving speed of the winch drum is configured to have a value that is proportional to an absolute value of a difference between the monitored tension of the spoolable medium and a predetermined tension set point.

A floating platform comprised of a tower, buoyant outriggers, and an articulated arm can be used in one embodiment to support an offshore wind turbine. The buoyant articulated arm is positioned with a winch system that supports the tower in a nearly horizontal position during assembly at shore and during transport. The winch and articulated arm elevate the system into its operational position at sea. The tower may include a keel structure to reduce motions and stresses on the system. The floating platform may rotate about an area surrounding an anchor system without active wind alignment equipment. The natural alignment with the wind allows for optimization of the structure, resulting in lighter-weight, less material mass and ultimately lower cost. The horizontal transport alleviates clearance restrictions of many bridges. Requiring neither large cranes nor specialized ships during installation, its ability to raise itself is scalable to large sizes lowering cost.
