Norway’s DOF Group has revealed a trio of new charters worth more than $253m for multipurpose support vessels (MSVs) in Brazil.

The deals are a combination of extensions and new firm periods for energy major Petrobras.

The 74-loa Skandi Chieftain (built 2006) and Skandi Commander (built 2007), and the 79-loa Skandi Olympia (built 2009), have been booked on three-year deals.
