Abstract: A wind turbine support system configured to support an off-shore wind turbine, an offshore wind turbine farm and a method for controlling a floating offshore wind park with such turbine support system are described. The wind turbine support system includes: a floating body configured to hold a lower end of a tower of the wind turbine; and a single point mooring system. The single point mooring system includes a seabed anchor; and a mooring line configured to be connected to the seabed anchor at a first end thereof. The floating body has a bow and a stern, and the bow is configured to be connected to a second end of the mooring line.

Abstract: A tower structure particularly suited for a wind turbine includes a lower tower section formed of concrete and an upper tower section formed of steel. A transition system connects the upper tower section to the lower tower section, the transition system including a concrete component having a tubular wall with a base portion fixed on the lower tower section and a head portion connected to the upper tower section. The head portion extends radially outward beyond the upper tower section. A plurality of first tensioning tendons extend longitudinally at least partially through the tubular wall and are anchored to the concrete component at a top face of the head portion at locations radially outward of the upper tower section.

Abstract: The present disclosure is related to a device 100 configured for aligning a first hole 131 of a first flange 130 with a second hole 141 of a second flange 140. The device 100 comprises a base 101, a shaft 110 extending from the base 101 and a first and a second pusher 115, 116. The shaft 110 is configured to move between a retracted position and an extended position. The shaft 110 in the extended position extends from the first hole 131 into the second hole 141. The first and second pushers 115, 116 are also configured to be moved radially outwardly from the shaft 110 to exert pressure against an inner wall of the first and second holes 131, 141. Methods for aligning a first and a second hole 130, 140 are also provided.
