Norway's Dof has secured a year's work for an anchor-handler in Brazil.
Its Norskan Offshore unit has chartered the 2,600-dwt Skandi Fluminense (built 2007) to Petrobras.
The term starts in July, with ROV work included.
Dof also said it has been awarded a contract by Chevron North Sea for the 4,700-dwt platform supply ship Skandi Kvitsoy (built 2012).
The contract will be for a period of approximately 140 days, starting in June, supporting drilling operations in the North Sea.
