Minesto has ordered a modified version of Subsea Riser Products’ (SRP) Rocksteady bottom joint system, for its tidal energy power plant Deep Green.

Delivery is scheduled for the first quarter of 2017.

The bottom joint functions as a locking mechanism between Deep Green’s tether and the seabed foundation. Rocksteady comprises two parts, where one part is integrated in the seabed foundation and the other in the tether. The two parts are joined together with an automatic locking device, the company explained.

“With Rocksteady, we get a product that is fully offshore certified, built for a service life of at least 25 years, while the design of the system allows for cost-effective operation and maintenance. An important argument for why we chose Rocksteady is quality assurance. It has a proven performance and is verified in actual use,” said Dr Martin Edlund, CEO of Minesto.

He added: “We have recently recruited expertise from the offshore sector that gives us valuable knowledge and experience in the further development of Deep Green. With our new supplier agreement with SRP, we have access to the same kind of skills also in the supply chain, which of course is positive.”
