The generation of electricity is described, using an offshore wind turbine. A generating sub-assembly 101 is supported by support mechanism (103) upon a support structure 102. The generating sub-assembly has a wind-responsive turbine and an electrical generator. The support structure includes a buoyancy portion (106) for submersion in water and a mast portion (108) extending from said buoyancy portion to extend the generating sub-assembly above the waterline. The support structure is buoyant and is free to roll when floating in water and the support mechanism is hinged to allow the generating sub-assembly to maintain an operational angle during the rolling of the support structure.

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.

This relates to vessels in general, but in particular to vessel designed to be exposed from low to medium to high waves. Both for comfort of persons, animals or fragile goods, steady sailing is preferred, without causing the waves slamming in on the vessel hull or excessive pitching of the vessel. This is also the case for service and supply vessels performing operations in relation to offshore or subsea installations. To obtain a solution to the aforementioned issues the present invention provides a vessel, wherein a stern of the vessel extend below a design waterline (Tdwl), and wherein opposite side faces of the stern, when seen in an opposite direction of the vessels primary sailing direction, form an acute angle under and above the design waterline (Tdwl) to decrease the vessels displacement in the rear end and are adjoined along at a line of symmetry forming a stern centerline.

A boat stabilization system includes a first radar unit constructed and arranged to be associated with a port side of a boat so as to obtain wave data of a port side wave prior to the port side wave contacting the port side of the boat. A second radar unit is constructed and arranged to be associated with a starboard side of the boat so as to obtain wave data of a starboard side wave prior to the starboard side wave contacting the starboard side of the boat. A control unit is connected with each of the first and second radar units and constructed and arranged to develop, based on the wave data of the port side wave and the starboard side wave, a three-dimensional wave map. The control unit is constructed and arranged to control a boat stabilizing device based on the wave map.

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.
