Siemens has completed installation of the offshore platform for the direct-current connection HelWin2.
The newly installed HelWin2 platform lies 35 kilometres north of the island Helgoland, directly adjacent to the HelWin1 platform Siemens erected earlier in August 2013. Earlier this year in April Siemens already erected the BorWin2 platform off the coast of Borkum. In total Siemens builds five North Sea grid connections for TenneT. The first four are to begin commercial operation successively over the second half of 2014 and the first half of 2015, and provide transmission capacity of over 2.9GW. The fifth connection, BorWin3, is to be ready for operation in 2019. The platforms are designed to operate for decades in the rough North Sea conditions, and are fully automated. The HelWin2 platform was constructed and installed by Heerema. The marine and land-based cabling were supplied and laid by the Prysmian Group.
