Load out works started on the 18th of February. With 120 m gantry crane the jackets have been lifted and moved to the barge and set in grilleages. Depending on place on barge each foundation moved 90, 60 and 30 m.
After rigging removal from jackets sea fastening has been installed. All load out operations with rigging, ballasting and fastening installation for one jacket took about 24 work hours.
The barge from Ostrów Brdowski island in Szczecin (Poland) sailed away on the 23 of February, direction Świnoujście. By the favourable weather the transport should reach Cuxhaven (Germany) in six days.
Following on from the successful execution of Ørsted’s Race Bank Transition Pieces (contracts signed in 2015), Ørsted has awarded ST³ Offshore with a second contract to fabricate 20 Suction Bucket Jackets, for the Borkum Riffgrund 2 OWF. Jackets produced for this project are foundations designed on an equilateral triangle plan (footprint: 28 m), 60 m high.
Borkum Riffgrund 2 will be located approximately 34 km North of the island Borkum in Germany, 54 km off the coast of Lower Saxony, next to Borkum Riffgrund 1.
The Borkum Riffgrund 2 Offshore Windfarm has a target power generation capacity of 450 MW using turbines mounted on a total of 56 steel foundations where 20 foundations are jackets and the remaining 36 foundations are monopiles. It will feature the largest wind turbines in German waters: 56 MHI Vestas 8 MW wind turbines with rotor spans of 164 meters. The offshore wind farm will supply CO2-free power equivalent to the annual electricity consumption of approximately 460,000 German households.
