Roxtec has secured a major contract to deliver its innovative safety seal solutions to an ambitious £1.5billion offshore wind farm project in the North Sea.

Roxtec UK managing director Graham O’Hare said the firm will deliver cable transit systems which are a key safety component to safeguard workers, structures and equipment on a substation platform being created as part of the Dudgeon Offshore Windfarm.

The deal will see a wide range of sealing solutions used on the platform, which will sit 20 miles offshore near the seaside town of Cromer in North Norfolk.

Mr. O’Hare said the cable sealing systems will meet the long-term lifecycle of the 402MW wind farm whose turbines will provide power to 410,000 UK homes and which is set to be commissioned during 2017.

“We have been chosen for this ambitious renewable energy project because we are industry leaders in sealing solutions for the renewables sector,” he said. “We have been involved in cable sealing projects across more than 40 offshore wind farms in Europe.

“The Dudgeon wind farm project will see the delivery of customized 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.

“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 Mr. 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.

“Sealing cables is an important safety factor and Roxtec has specialist knowledge in this sector, this is why we have devised an accredited technical CPD seminar covering the importance of sealing cables offshore. This is based upon industry standards and our own practical experience.”
