Norway's Fred. Olsen Windcarrier (FOWIC) has added another wind farm support ship to its fleet in a deal with Keppel Offshore & Marine of Singapore.

The shipowner said it has acquired 51% of the Keppel company, Seafox 5 (SF5), that owns the 11,000-dwt Seafox 5 (built 2012).

Under the agreement, FOWIC will acquire the shares and a pro-rata part of shareholder loans for $73.6m.

SF5 had total assets with a book value of €188.3m ($214m) earlier this year.

FOWIC will have the vessel under commercial, technical and administrative management.

"With larger crane and longer legs, the Seafox 5 is complementary to Brave Tern and Bold Tern, the existing two jack-up wind turbine transport and installation vessels of the company," FOWIC said.

"The acquisition further strengthens the position of Fred Olsen Windcarrier in the growing global offshore wind markets, [ie] the US and Asia, and will also be an enabler for activities related to oil and gas decommissioning works."

FOWIC also has seven crew boats.
