The current total global offshore wind power capacity is 64.3 gigawatt (GW) with the United Kingdom contributing 22% making it the second-largest contributor after China (49%).
Sarens has been commissioned by the port of Wergeland, in Norway, to replace the bearings in the 5 floating wind turbines by the end of September. After the replacement, all units will be reconnected to the Hywind Scotland site.
The world’s first floating wind farm, the 30 MW Hywind Scotland pilot park, is operated by Hywind (Scotland) Limited. It is currently undergoing maintenance works with its five turbines being revised and repaired. Hywind Scotland delivers enough power to supply around 35,000 homes in the UK. The current total global offshore wind power capacity is 64.3 gigawatt (GW) with the United Kingdom contributing 22% making it the second-largest contributor after China (49%).
Hywind Scotland, located 25 kilometres offshore Peterhead in Aberdeenshire, comprises five Siemens Gamesa 6 MW turbines mounted on SPAR-type foundations. This year, the wind turbines are undergoing maintenance at the Wergeland Base, on the west coast of Norway, before being reconnected.
Sarens, world leader in heavy lifting, engineered transport and crane rental services, has been commissioned by the port of Wergeland, in Gulen (NO), for the replacement of the bearings in the 5 floating wind turbines. Sarens' scope of work includes the provision of cranes to lift nacelles and blades from the floating wind turbines, transport of these components, and delivery of a skidding system to move the generator in and out of the workshop.
Sarens deployed a range of advanced equipment, including the LR12500-1.0 crane with a tagline system. This posed a significant challenge in terms of delivery and setup, which required precise timing and coordination. Featuring an HDWB2 configuration with a 90-metre main boom and a 66-metre luffing jib, this crane was pivotal in this project. The crane’s configuration included four tagline winches, ensuring safe and efficient lifting operations. Specialised SPMTs were used for transporting blades and nacelles. A custom-designed lightweight spacer beam was also employed to facilitate the transport of the 75-metre long, 26,5-ton blades.
This Liebherr LR 12500-1.0 was first used in Rostock, where the brand-new crane lifted the monopiles for their assembly in the Baltic Eagle's offshore wind farm. It was the first unit of this model delivered by the German manufacturer Liebherr.
Sarens has extensive international experience in the assembly and maintenance of wind farms. It has participated in various installations in France such as Fécamp, Saint Nazaire, Provence Grand Large and in the lifting and transport work for the foundation bases of the new offshore wind farm in Saint Brieuc, located off the Brittany coast. During this project, Sarens successfully transported loads weighing over 1,150 tons. More recently, Sarens has been actively involved in the reception and loading operations of monopiles and transition pieces for 176 turbines for the Coastal Virginia Offshore wind farm and the marshalling and installation of 62 monopiles in the Moray West offshore wind farm, each weighing up to 2000T, the largest and heaviest XXL monopiles ever to be handled in the UK.
