Innosea has been contracted by DEME to assess the operability of its jack-up vessel for the construction of France’s Iles d’Yeu and Noirmoutier offshore wind farm.
The development has a planned capacity of 496MW and is situated across an area of 83 square kilometres, off the Vendée coast, at water depths between 19 metres and 36 metres.
The Innovation ship is DEME Group’s heavy-lift DP2 jack-up offshore installation vessel.
The ship is 174.5 metres long, 42 metres wide, and equipped with a 1500 tonne crane.
As part of its scope of work, Innosea will provide a range of advanced engineering analyses to support the jack-up vessel, including hydrodynamic and impact modelling using OrcaFlex and finite element analyses modelling for analysing stresses on the jack-up legs.
“Maximum operability of a jack-up vessel is key for securing the safe and timely installation of the monopile foundations on an offshore wind project,” said Innosea project manager Valentin Arramounet.
“Detailed evaluation of the vessel’s reactions to the environmental loads is therefore critical for early risk mitigation in the offshore construction programme, thereby adding value to the project and the windfarm’s future bottom line.”
Innosea is part of the international renewable energy consultancy, OWC, and is wholly owned by Oslo-listed consultancy group ABL Group.
