Maersk Supply Service has completed the installation of the mooring, anchoring and quick connect solution for the 2 MW DemoSATH, the first floating wind turbine to be connected to the Spanish grid.
Maersk Mariner installed six mooring lines, consisting of hybrid fiber chain and rope lines, and six dredge anchors in the BiMEP test area in early May.
The mobilization and loading of the mooring elements and the preparation of the vessel were carried out at the wharf of Punta Sollana, in the port of Bilbao, where the onshore construction of the float is currently underway.
Lines will be retrieved from the seabed for plug-and-play connection to the unit later this year.
The Spanish company Saitec Offshore Technologies is leading the development of the project, in collaboration with RWE.
“The installation of the SATH mooring lines worked perfectly. In the future, we will use them in all our commercial projects which are currently in the planning phase. The operations have been a great success since the first design stage and the execution has been exceptional,” mentioned Araceli MartinezHead of Engineering at Saitec Offshore Technologies.
The 2 MW turbine will be tested under real-sea operating conditions in a harsh Atlantic environment. The BiMEP facilities test field is located two miles off the coast of Biscay, where the sea is 85 meters deep. DemoSATH will generate enough electricity to cover the energy demand of more than 2,000 local homes.
“It’s great to see that the DemoSATH project has completed the next stage of offshore work, with the mooring system now in place – a milestone on our way to installing and commissioning the floating turbine more later this year, mentioned Chris Willowfloating wind development manager at RWE Renewables.
“As RWE, we see great potential for floating wind farms around the world, especially to unlock opportunities in countries with deeper coastal waters. With DemoSATH, we gain experience with innovative concrete-based platform technology and further expand our expertise in this growing market.
Meanwhile, onshore construction of the prestressed concrete floating platform continues at the Port of Bilbao, Saitec said. Work on the transition piece, the single point mooring and the landing stage are also carried out as well as installation work inside the floats. This will be followed by the launching operation of the platform, which will then be transported to its final deployment site at BIMEP.
“With the completion of the mooring system installation, the DemoSATH project is ready for foundation installation later this year,” mentioned Yvan Leynifloating wind director at Maersk Supply Service.
“We had good collaboration throughout the process, both in the planning and execution phase. The engagement of key stakeholders was instrumental in the success of the completion. With this project, we hope to contribute to the development and maturation of the floating wind industry.
This project aims to collect data and gain real-life knowledge on the construction procedure, operation and maintenance of the DemoSATH floating wind platform for a period of two years.
