RWE’s Kaskasi offshore wind farm – which will be Germany’s first offshore wind farm to come online since 2020 – is moving ahead, with 22 monopiles already installed.


DEME Offshore is responsible for the transport and installation work of the monopiles, transition pieces, turbines and inter-array cables. The company was also on hand to support the installation of the substation foundation. This was followed by the installation of the substation itself utilising the DP2 heavy lift vessel Gulliver – operated by DEME’s joint venture company Scaldis

The DP2 offshore installation vessel Neptune, in combination with Fred. Olsen Windcarrier’s Blue Tern, has been drafted in for the monopile installation. DEME is managing these tandem transport and installation operations and providing all the seafastening, handling and hammering equipment. 

DEME’s Sea Challenger has been lined up for the installation of the transition pieces and the subsequent wind turbine generator installation. The latter is under a direct charter with Siemens Gamesa.
