Roxtec Seals Dudgeon Deal

Roxtec has secured a contract to deliver its safety seal solutions for the 402MW Dudgeon offshore wind farm project.

Roxtec UK managing director Graham O’Hare said the firm will deliver cable transit systems to safeguard workers, structures and equipment on the wind farm’s substation platform.

The deal will see a wide range of sealing solutions used on the platform, which will sit 32 kilometres offshore near the seaside town of Cromer in North Norfolk, Roxtec said.

Roxtec UK managing director Graham O’Hare said the cable sealing systems will meet the long-term lifecycle of the GBP 1.5 billion wind farm whose turbines will provide power to 410,000 UK homes and which is set to be commissioned during 2017.

“The Dudgeon wind farm project will see the delivery of customised bulkhead and deck seals. Roxtec’s expert team has also been actively involved in the design of the platform seals, harnessing more than 15 years’ experience in offshore industries,” O’Hare said.

“Our seals are designed to be flexible with easy maintenance access and spare capacity for upgrades. They are both easy to install and inspect. This proved another positive factor when it came to winning this contract. Our team is further providing training as part of the deal.”

Roxtec’s sealing solutions are used for different applications in wind projects, from control cabinets to generators and converters. They offer protection against fire, gas, water pressure and corrosion and provide cable retention.

“Specific safety solutions for the Dudgeon windfarm project include delivering A0/A60 bespoke seals for HV and MV applications on the substation platform,” said O’Hare.

“We will seal array cables to MV switchgear and cables from MV switchgear to transformer input. Additional products will be used on the platform’s cables linking its transformer to its Gas Insulated Switchgear (GIS) and on export-to-shore cables.”

The Dudgeon offshore wind farm is owned by Statoil (35%), Masdar (35%) and Statkraft (30%), with Statoil in charge of developing the wind farm and will continue as its operator.

A2SEA’s Sea Challenger installed the first of 67 6MW Siemens turbines at the site on 7 January.
