Norwegian owner Rem Offshore is stepping up its push into wind farm work with an order for up to four construction service operation vessels (CSOVs).

The company has contracted Fincantieri-owned shipbuilder Vard to build two firm CSOVs at a combined priced of €100m ($118m), with options for two more.

The private shipowner, controlled by Age and Fredrik Remoy, said the new ships are "tailor-made" for global operations.
