Roxtec has delivered a package of cable sealing solutions for the Beatrice offshore wind farm off Scotland, including fireproof and watertight seals to secure high voltage cables on the two transformer modules.
Roxtec UK marine and offshore director John Kayes said the company supplied a series of customised and standard sealing solutions for the project’s substations.
“This includes openable sleeves for transformer feeds, arrays and busducts, along with transits for high voltage and medium voltage cables. In addition, we delivered seals for earth cables and HVAC pipes as well as low voltage transits for small power and control. Low voltage transits were used for cable tubes on a total of 84 jackets,” Kayes said.
The installation of the first Siemens Offshore Transformer Module (OTM) at the Beatrice site was completed in February, with the commissioning underway, while the second one is yet to be placed offshore. More than half of the jacket foundations have been installed so far. Inter-array and export cable installation works are also ongoing at the site.
“The Beatrice wind farm project is set to transform energy resources in North Scotland providing enough power for more than three times the number of homes currently in the Moray and Highlands region,” Roxtec’s John Kayes said. “It adds to our growing portfolio of work in the renewables sector having supplied more than 50 offshore windfarms in Europe.”
The 588MW Beatrice will feature 84 Siemens Gamesa 7MW wind turbines and two Siemens OTMs, all mounted on jacket foundations. The wind farm will be energised in phases and will be fully operational in 2019.
