Norwegian marine services group Kongsberg has clinched a contract to design the first offshore wind vessels ordered by domestic shipowner Awind.

The Oslo-listed group said the NOK 250m ($30.1m) deal is to develop and equip two construction service operation vessels for the subsidiary of Integrated Wind Solutions.

They are part of a deal lined up by Awind at China Merchants Heavy Industry. The company holds options for a further four wind ships.

The newbuilding contract price has not been revealed.

Kongsberg said the firm vessels will be based on UT 5519 DE designs, for delivery in 2023.

"The vessels are designed with a clear focus on reduced emissions and enhanced sustainability," it added.

The ships will include Kongsberg permanent-magnet Azimuth thrusters, generators, electrical systems and a fully integrated bridge with navigation, dynamic positioning and automation systems.

"Awind’s determination to promote humane, environmentally friendly, safe and efficient operation is entirely consistent with Kongsberg's mission to incorporate sustainability in everything we do," said Kongsberg Maritime president Egil Haugsdal.

Ripple effects

"This cooperation will have positive ripple effects across the entire organisation, as well as reinforcing Kongsberg Maritime’s market position in the growing renewable energy segment."

Kongsberg claims the UT 5519 DE has a novel hull form and propulsion set-up, incorporating results from research and development projects, as well as operational experience from existing Kongsberg wind farm service vessels.

"We are very pleased to strengthen and build on our relationship with Kongsberg Maritime, both through the design and development phase and in the future," said Christopher Andersen Heidenreich, Awind's managing director.

Integrated Wind Solutions has a stated ambition of becoming a leading provider of offshore wind services.
