Watertight Cable and Pipe Seals for Floating Wind Turbines

Saitec Offshore Technologies and Roxtec are collaborating for the future of renewables. Saitec Offshore Technologies in Bilbao, Spain, has specified Roxtec cable seals for their innovative SATH floating wind turbine concept.

After having experienced the seals in the previous BlueSATH project, they decided to use several different Roxtec solutions for their DemoSATH 2 MW project.

“Roxtec offers a customized solution for our floating wind project. We need offshore environment protection of the internal equipment and cabinets of the WTG at the transition piece and other areas of the floating platform. We developed an excellent collaboration with their team, and we believe that their watertight solution will have a great performance in harsh offshore conditions,” says Aitor Sanz, Offshore Wind MEP Manager at Saitec Offshore Technologies.

Fruitful Project Collaboration

Saitec Offshore Technologies has designed the SATH floating wind concept, a unique floating platform for offshore wind turbines suitable for shallow and deep waters. As Saitec had previous experience in working with Roxtec, they decided to continue the collaboration on this project. The sealing demand was a fully watertight solution for the offshore environment. Furthermore, the sealing solutions for partitions and cabinets had to be openable and removable in case more cables or ducts had to be installed.

Flexible and Customized Seals

Roxtec round seals and Roxtec rectangular and compact cable and pipe transits are used to seal off cable ducts for low-voltage and medium-voltage cables as well as for closing off refrigeration ducts from the exterior offshore environment. Roxtec seals adapt to cables and pipes of different sizes and are in this case used for marine type power cables ranging from 4 mm to 150 mm and for pipes from 15 mm to 25 mm. Roxtec also created a customized seal to help Saitec seal flat cables.
