Dof has fixed out five of its platform support vessels (PSVs), three of which are ostensibly for Saipem in offshore Guyana.
The Oslo-listed offshore support vessel specialist did not disclose the individual charter rates, but said the contracts have a combined value of NOK 425m ($49.4m).
Two thirds of the revenue will arrive this year.
Offshore Guyana
The 5,100-dwt Skandi Neptune (built 2001) has already begun survey work in Guyana and has a second contract period scheduled this year in field development construction support activities, Dof said in a filing.
