During the development of its new Offshore Transformer Module (OTM), Siemens team “threw away the rulebook” and got the weight down, because stripping the weight means stripping the costs. It removes the need for specialised heavy-lift vessels and allows using vessels already deployed on the field to install turbine foundations.
This is according to Mike Grainger, Director Grid Access at Siemens AG, with whom we spoke at the beginning of June in London.
The company sent its first of two OTMs for the Beatrice offshore wind farm in May, and will also deliver the AC solution for the Albatros project in Germany.
In terms of DC grid access solutions, Siemens is working on the BorWin gamma platform and has received an order from TenneT to supply the entire technology for direct-current transmission for DolWin6, a grid connection for offshore wind farms in the German waters of the North Sea. The latter is not mentioned in our interview since the company announced the order in mid-July.
Together with its wind power division, now Siemens Gamesa, Siemens has also embarked on the delivery of integrated solutions for offshore wind.
