THE SCIENCE OF SEALING


FEATURE SPONSOR


‘SCIENCE OF SEALING’ FOR WORLD’S


MOST POWERFUL TIDAL TURBINE Manufacturer Roxtec is an industry leader in sealing solutions for the renewables sector where its products have featured in offshore windfarms across Europe


Roxtec UK Managing Director


Clive Sharp explains how its expertise has also been


harnessed by the wave & tidal energy sector on a project involving one of the largest tidal turbines in the world.


INNOVATIVE FLOATING TIDAL TECHNOLOGY Scotrenewables Tidal Power based


in Orkney, Scotland has over the past decade developed a highly innovative floating tidal technology. In 2017, it launched a full scale demonstrator, the SR2000, the world’s most powerful tidal turbine. Since its launch in 2017, the turbine has undergone an intensive demonstration programme at the European Marine Energy Centre (EMEC), in the harsh wave & tidal environments of the North Sea.


SUPPLYING SEALING SOLUTIONS Roxtec was commissioned to supply sealing solutions for the SR2000 2MW floating turbine measuring 65m in


length, 3.6m in diameter and weighing 550 tons. Super-strong watertight seals were installed to protect the turbine’s vital control systems from flooding and water ingress over a 20-year period. The turbine was assembled at the Harland and Wolff shipyard in Belfast and commissioned in Orkney, with Roxtec providing support at both locations throughout the project.


Multiple EC&I cables (electrical control and instrumentation) of various sizes were sealed on the turbine through every bulkhead between sections.
