France-based offshore services provider Bourbon reports it has won a contract to carry out the mooring installation of the first floating wind turbine in France, the two-megawatt FLOATGEN.
FLOATGEN is a joint venture project between Ideol, France, Bouygues Travaux Publics, France, Ecole Centrale de Nantes (ECN), France, RSK Group, UK, Zabala, Spain, the University of Stuttgart, Germany, and Fraunhofer IWES, Germany.
The floating turbine, which is currently under construction at the Port of Saint-Nazaire, France, will consist of a Vestas, Denmark, V80 wind turbine mounted on a square ring-shaped floating foundation, known as the ‘damping pool’, developed and patented by Ideol and built by Bouygues Travaux Publics.
The mooring installation will take place during the summer of 2017 based on a method jointly established by Bourbon and Ideol’s engineering teams in collaboration with ECN.
The wind turbine will be installed at the SEM-REV site near Le Croisic, Brittany, by the end of the year.
Bourbon’s Subsea Services team will be responsible for the project management, mooring installation and engineering.
An anchor handling tug supply (AHTS) vessel and remotely operated vehicles will be used for the pre-tensioning of the mooring system.
“This project demonstrates the Bourbon team’s commitment to offer integrated solutions in all offshore and subsea marine services areas and work towards the development of tomorrow’s energy resources. We are proud to be part of this project and to support the Centrale Nantes’ team at SEM-REV,” said Patrick Belenfant, Bourbon’s senior vice president Subsea Services.
The FORESEA programme has awarded “recommendations for support” to 15 offshore renewable energy technologies following its second call for applications.
The awards will provide a boost to technology developers by allowing them to test their technologies on the open sea, attract further investment, and move further along the path to commercialisation.
FORESEA (Funding Ocean Renewable Energy through Strategic European Action) is an 11 million euro (£9 million) project which helps to bring offshore renewable energy technologies to market by providing free access to a world-leading network of test centres: the European Marine Energy Centre (EMEC) in the UK, SEM-REV in France, SmartBay in Ireland and Stichting Tidal Testing Centre (TTC) in the Netherlands. Access is awarded through a series of competitive calls for application. It is financed by the Interreg North-West Europe (NWE), a European Territorial Cooperation Programme funded by the European Commission with the ambition to make the North-West Europe area a key economic player.
FORESEA’s user selection board has now awarded a Recommendation for Support to demonstration projects led by the following technology developers to test at the indicated test centre: Aqua Power Technologies (EMEC); ASVS (SEM-REV); Current2Current (EMEC); Dresser-Rand (EMEC); Finima Innovations (EMEC); FishFlow Innovations (TTC); Flex Sense (SEM-REV); FMGC (SEM-REV); Oceanlinx (EMEC); Scotrenewables Tidal Power (EMEC); Sigma Energy (EMEC); Sustainable Marine Energy (EMEC); Swirl Generators (EMEC); and Tocardo (TTC and EMEC).
Hans van Breugel, chief executive officer of Netherlands-based Tocardo, welcomed the award: “The FORESEA programme enables Tocardo to improve the dynamic umbilical power cable for our Universal Foundation Structure (UFS), needed for power evacuation from the semi-sub UFS platform to the power cable on the seabed. Deployment of systems in real-life conditions will increase the project developer’s confidence and reduce the cost of capital in projects.”
Roelof Schuitema, project manager at the Tidal Testing Centre, indicated the importance of the announcement: “Developers are being supported through the FORESEA programme to access TTC for the first time, and this marks the beginning of an exciting new period for us. We look forward to welcoming Tocardo and Fishflow Innovations to TTC soon.”
Aberdeen, UK-based subsea cable and connector specialist Hydro Group reports it has completed a major contract with technology developer and supplier of tidal turbines Andritz Hydro Hammerfest (AHH), Norway.
The agreement saw Hydro Group supply complete connection systems for three turbines on the world’s most advanced multi-turbine tidal stream energy development.
This second MeyGen contract followed on from an announcement in November 2015 regarding a contract with UK-headquartered Atlantis Resources – 86% owner of MeyGen Limited – for which Hydro Group supplied the complete export connection system for one of the tidal turbines. This most recent contract win saw Hydro Group, contracted by AHH, supply the complete connection system for the remaining three turbines.
As part of phase 1A of the ground-breaking 398-megawatt tidal array project, four submerged turbines, generating six megawatts, have been installed in the Pentland Firth, Scotland, with more than £50million having been raised to finance the initial stage.
Doug Whyte, managing director at Hydro Group, said: “This significant MeyGen project is further testament that Hydro Group is seen as a major operator and supplier to the renewable energy markets. With several decades of renewable energy industry experience behind us, Hydro Group is at the forefront in the development of cables, terminations, connectors and junction boxes, with involvement from the initial prototype stage through to design and manufacture.”
The scope of work involved Hydro Group providing the connection management system and interfacing the export cable up to the nacelle, including the dynamic cable, the in-board connection system and the mechanical loading system, transmitting a power output of 1.5 megawatts at four kilovolts per turbine and incorporating fibre optic links.
