Roxtec Seals for Floating Tidal Turbine

Posted by Irina Tabakina

Roxtec provided its waterproof sealing solution to what is called  the largest and most powerful tidal turbine in the world. Roxtec UK managing director Graham O’Hare said the deal with Scotrenewables Tidal Power Limited involved Roxtec supplying the new SR2000 2MW floating turbine which is 65m long, 3m diameter and weighs 550 tons.
 “The turbine was built in Orkney and at the Harland and Wolff shipyard in Belfast, and Roxtec provided support at both locations throughout the project,” O’Hare said. “We have sealed a high volume of multiple electrical control and instrumentation cables of various sizes on the turbine through every bulkhead between sections. We could offer the highest standards of certified waterproof bulkhead seals. The cabling in the turbine is extensive and runs its entire length through 10 compartments inside the floating hull, and also cable sealing within the generator nacelles, and over an exposed section linked to topside power, control and communication equipment.
O’Hare said during the planning phase Scotrenewables designers were able to use Roxtec’s Transit Designer computer software. “Our software enabled their team to produce detailed drawings, quickly and simply, of cable and pipe locations which makes the installation process faster,” O’Hare said.
