June 21 - Following an EU tender against international competition, a consortium consisting of Fichtner GmbH & Co. KG and SeaRenergy Offshore Holding GmbH & Cie. KG has been awarded a contract by TenneT covering design reviews for checking, commenting on and approving designs and documents within the scope of the project BorWin5 to deliver and construct the offshore HVDC converter platform BorWin epsilon. This involves checking and documenting project parameters to ensure their compliance with contractual requirements and the client’s technical specifications, checking the feasibility of the transport and installation concept with regard to international norms, standards and regulations, and checking and approving the “as-built” documentation.

With the grid connection project BorWin5, TenneT will connect the 900 megawatt offshore wind farm EnBW He Dreiht to the German mainland via 230 kilometres of sea and land cables.

KG are now looking forward to continuing their successful cooperation.
