A system comprises a carrier structure configured for carrying a module and a floating support structure configured for supporting the carrier structure. The carrier structure comprises first connection means and the floating support structure comprises second connection means, whereby the first and second connection means are configured for releasable connection and comprise contact surfaces that prevent the carrier structure from rotating about its longitudinal axis when the two structures are connected. A transportation and installation apparatus for the carrier structure is configured for being arranged on a floating vessel.

A floating foundation for an offshore wind turbine has a center pipe, a buoyancy section, a weight section, and a plurality of wire ropes, The buoyancy section is connected to the center pipe to keep the foundation floating. The weight section is connected to the center pipe to provide stability to the foundation. The wire ropes are connected to the buoyancy section and the weight section and are arranged for being tensioned so as to add bending strength to the foundation The floating foundation has hoisting means for lowering or raising the center pipe. The hoisting means includes winches for increasing or decreasing a length of each of wire ropes connecting the buoyancy section and the weight section, for lowering or raising the center pipe of the floating foundation. A system is disclosed for extracting energy from wind. A method is disclosed for installing a wind turbine.

A hybrid floating offshore wind turbine energy conversion system using light weight solid syntactic buoyancy material columns for offshore application. Each wind turbine includes a deep draft Spar hull combined with several semi-submersible syntactic columns for extra buoyancy and stabilization.

A platform for a semi-submersible floating type offshore structure according to an exemplary embodiment of the present invention includes a main body which is installed on the sea and has an arrangement structure in which a plurality of pontoons is combined to form a plurality of polygonal shapes; and a protrusion member connecting unit which extends from each corner of the main body and connects a protrusion member outwardly protruding from the main body to the main body.

A width-adjustable packaging bag shaper, a bag maker, a packaging machine, and a method. The packaging machine including the bag maker, a traction device and a heat sealing device are respectively arranged above the bag maker, and a width adjustment device adjusts the distances between different sub bottom plates in a front bottom plate and a rear bottom plate by using a leadscrew and slide block mechanism, and then adjusts the width of a bottom plate. The leadscrew and slide block mechanism is used as the width adjustment device of the automatic width-adjustable noodle packaging bag shaper system, and four bottom plates are respectively fixed to the width adjustment device, so the leadscrew and slide block mechanism in operation is accurate in range of adjustment, is suitable for various widths of packaging bags, and has very important significance for the three-dimensional shaping effect of the packaging bags.

Provided is a floating wind turbine including a hull, a wind turbine mounted on top of the hull and a counterweight suspended below the hull by a counterweight suspension is described. Also, a method for the installation is described. The counterweight includes one or more counterweight buoyancy tanks. When the internal volume of the buoyancy tanks is filled with air, the total buoyancy of the counterweight is close to or greater than its weight. Hereby it is capable of floating in a towing/maintenance position with moderate or no support in the vertical direction from the hull or other vessels. During towing, the hull substantially has the character of a barge, substantially relying on a large waterplane area and shallow draft to maintain stability.

Provided is a method for moving an object between a platform of a wind turbine and a deck of a vessel, wherein the platform is located at a tower the wind turbine, wherein the object is moved vertically by a hoist coupled between the object and at least one fixation site the wind turbine located above the platform and the deck, wherein the object is deflected radially from the tower by a puller coupled between the object and the vessel.

A floating structure in the form of a spar which from a base (12) includes a first ballast weight (16), an entrapped fluid compartment (18), an equipment compartment (20), a second ballast weight (22) and a topside (24) wherein, in use, the structure floats with the water line between the topside and the second ballast weight. The arrangement utilises vertical spacing between physical masses and entrapped fluid to increase the natural period in pitch and roll motions to provide high stability. Embodiments of entrapped fluid compartments are described. The floating structure finds application in hydrocarbon recovery in shallow water and offshore renewables.

A buoy (10) comprising a central column (12), an outer frame (14) attached to the central column with buoyancy which may be provided by the outer frame and/or by attached buoyancy units (16). The central column is negatively buoyant and is normally open at one end to allow water to flow in, and create an oscillating water column caused by waves. This water column dampens the effect of wave or other forces on the buoy, thus providing a more stable foundation for a wind powered generator. A further generator may be provided to extract energy from the oscillating water column. The buoy is normally attached to an anchor by one or more tension leg tethers which maintains the buoyancy below the surface of the water which has also be found to increase stability. The anchor may be a modular gravity base anchor.
