A tuned mass damper for damping an oscillating movement of a structure along a first direction is provided. The tuned mass damper comprises a mass arranged to perform a reciprocating movement along the first direction in response to the oscillating movement of the structure, wherein the mass comprises a braking mechanism configured to at least partially brake the movement of the mass along the first direction when the mass exceeds a predefined speed.

Tuned mass dampers for damping an oscillating movement of a structure

Methods for controlling tension in mooring lines of a floating offshore structure having a buoyancy structure including one or more water tanks and the buoyancy structure providing excess buoyancy are provided. The methods comprise varying the mass and/or the center of gravity of the floating offshore structure by varying the quantity of water in one or more of the water tanks. Also, floating offshore structures are disclosed, the structures comprising a buoyancy structure having one or more floater tanks providing excess buoyancy, and a plurality of tensioned mooring lines, and further comprising a control system for increasing and decreasing a quantity of water in one or more of the floater tanks. Also, possible uses of floating offshore structures are provided wherein under standard operating conditions, the floater tanks are at least partially filled with water.

Floating offshore structures

Wind turbines are provided comprising a support structure having a tower and a nacelle mounted on the support structure. A first region (damper region) of the wind turbine including at least a first part of the nacelle is flexibly coupled to a second region (to be damped) of the wind turbine including at least the support structure. Methods are also provided for determining a suitable stiffness of the flexible coupling of the damper region to the region to be damped of any one of said wind turbines. These methods comprise determining a modal mass of the region to be damped depending on a given tower bending mode; and determining the stiffness of the flexible coupling of the damper region to the region to be damped depending on the calculated modal mass of the region to be damped and on the mass of the damper region.

Wind turbines and methods

Floating TLP wind turbine comprising a buoyancy structure, a plurality of braces, one or more tensioned mooring lines for each brace, and a support structure arranged on the buoyancy structure. The braces extend radially outwardly from a region of the buoyancy structure or support structure, each brace having a distal end portion with respect to the buoyancy structure or support structure. Each distal end portion of the braces comprises a guiding element to allow a guided passage of a tensioned mooring line. Each of the tensioned mooring lines is anchored to the seabed at a first end, and attached/coupled to a region of the buoyancy structure or support structure at a second end, said region being above the region of the buoyancy structure or support structure from which the braces extend radially outwardly. Each tensioned mooring line is guided by the guiding element of the corresponding brace.

Floating wind turbine

A floating offshore structure comprises a buoyancy structure arranged such that in use it remains below the sea level and a tower, wherein the buoyancy structure is attached to a tower by a connecting structure, the connecting structure comprising one or more openings arranged such that in use they remain below the sea level, and the one or more openings being dimensioned such that sea water can flow into and out of the connecting structure with variations of the sea level.
