The DemoSATH mooring, anchoring and quick connect solution is defined for the 2 MW turbine which will be tested later this year and which will be the first floating turbine connected to the Spanish grid.


In early May, Maersk Supply Service completed the installation of six mooring lines (composed of hybrid fiber chain and rope lines) and six trailing anchors with Maersk Mariner. The mobilization and loading of the mooring elements and the preparation of the ship were carried out at the wharf of Punta Sollana, in the port of Bilbao (Spain), where the onshore construction of the float is currently underway.


Once loaded, the ship left the Port for the installation site of the BiMEP test area where the connection and installation of the elements took place. Lines will be retrieved from the seabed for plug and play connection to the unit later this year.


“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 stage. The operations have been a great success since the first stage of the design and the execution has been outstanding,” commented Araceli Martínez, Chief Engineering Officer at Saitec Offshore Technologies.


“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. 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 are gaining experience with a innovative concrete-based platform technology and further expand our expertise in this growing market,” said Chris Willow, Head of Floating Wind Development at RWE Renewables.


“With the completion of the installation of the mooring system, the DemoSATH project is ready for the installation of the foundation later this year. We had good collaboration throughout the process – both in the phase planning and execution. The commitment of key stakeholders, from the developer to the float manufacturer, was instrumental in the successful completion. With this project, we hope to contribute to the development and maturation of the floating wind industry,” said Yvan Leyni, director of floating wind at Maersk Supply Service.


Meanwhile, onshore construction of the prestressed concrete floating platform continues at the Port of Bilbao. 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.


The DemoSATH signifies a stepping stone in the commercialization roadmap of the SATH technology. The 2 MW unit will be tested under actual offshore operating conditions in a harsh Atlantic environment. The BiMEP facilities test field is located 2 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.


This project aims to collect data and acquire real knowledge about the construction procedure, operation and maintenance of the DemoSATH floating wind platform for a period of 2 years.
