Maersk Supply Installs Mooring For Spanish Offshore Wind Turbine

Maersk Supply Installs Mooring For Spanish Offshore Wind Turbine
Maersk Supply Service has installed the six mooring lines and six anchors at the BIMEP test site from the Maersk Mariner anchor handler.

Maersk Supply Service has undertaken the installation of the six mooring lines and six anchors of DemoSATH at the BIMEP test site from the anchor-handling vessel Maersk Mariner.

DemoSATH mooring, anchoring, and quick connect solution is set for the 2MW turbine that 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 and six drag anchors with the vessel.

The mobilization and loading of the mooring lines elements and preparation of the vessel was done at Punta Sollana quay, in the port of Bilbao, where the onshore construction of the floater is currently underway.

Once loaded, the vessel left the Port towards the installation site at BiMEP test area where the elements’ connection and laying took place. The lines will be recovered from the seabed for a 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 that are currently in the planning stage. The operations have been a great success since the earliest stage of design and the execution has been outstanding”, commented Araceli Martínez, Chief of Engineering at Saitec Offshore Technologies.

“It is great to see that the DemoSATH project has completed the next step of the offshore works, with the mooring system now in place – an important milestone on our way to the installation and commissioning of the floating turbine later this year. We as RWE see great potential for floating wind farms worldwide – especially to unlock opportunities in countries with deeper coastal waters. With DemoSATH we are gaining experience with innovative concrete-based platform technology and are broadening our expertise in this growth market further,” 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 have had good collaboration throughout the process – both in the planning and the execution phase. The engagement of the key stakeholders has been 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 for Floating Wind at Maersk Supply Service.

Meanwhile, the onshore construction of the prestressed concrete floating platform continues at the Port of Bilbao. Works on the transition piece, single point mooring, and boat landing are also carried out as well as installation works inside the floaters. This will be followed by the launching operation to put afloat the platform which will be then transported to its final deployment site at BIMEP.

The DemoSATH means a steppingstone in SATH Technology commercialization roadmap. The 2MW unit will be tested against real sea operating conditions in a harsh Atlantic environment. The test field at BiMEP facilities is located 2 miles off the Biscay coast. It will generate sufficient electricity to cover the energy demand of more than 2,000 local households.

This project aims to collect data and gain real-life knowledge from the construction procedure, operation, and maintenance of DemoSATH floating wind platform for 2 years.
