 Wärtsilä, in consortium with IMS Ingenieurgesellschaft mbH, has been engaged by RWE Innogy, the renewable energy arm of the German utility company RWE,
as its designer to provide the basic design and consultancy services for
a jack up crane vessel. Two such vessels with GL class-approval have
been ordered by RWE Innogy to be used for constructing offshore wind
farms. The shipbuilding contracts have been awarded to Daewoo
Shipbuilding & Marine Engineering Co. Ltd. (DSME), and delivery of
the vessels is scheduled for late 2011.
Tailored specifically for year-round construction of offshore wind
farms, the Wärtsilä-IMS advanced jack-up crane vessel is designed to
remain operational under harsh Northern European sea and wind
conditions. It also sets new standards for reliability and
environmentally sound operation.
The basic design by Wärtsilä-IMS takes into account the specialised
needs involved for the construction of offshore wind farms. The vessels
are 100 metres long and 40 metres wide, and feature an 800-ton crane for
transporting and handling the foundations for the latest generation of
up to 5MW and 6 MW offshore wind turbines, as well as the turbine
towers, nacelles, rotors and blades. The vessels have sufficient deck
area and deadweight capacity to carry the components for up to four
complete wind turbine units or several foundations. For operation in
shallow water, a four-point mooring system is used, while in deeper
waters a DP2 dynamic positioning system controlling steerable thrusters
is employed.
The vessels are designated to undertake foundation and turbine
installation at RWE Innogy’s currently planned wind farms – “North Sea
East”, “Innogy North Sea 1” and “Gwynt y Môr”.
