Equinor has fixed two platform supply vessels from Eidesvik Offshore and Havila Shipping.
Eidesvik's 6,200-dwt Viking Queen (built 2008) and Havila's 4,000-dwt Havila Clipper (built 2011) have been fixed for a firm period of four months, plus options.
The vessels' respective contracts will both commence this quarter, according to filings from the shipowners on Tuesday.
No further details about the contracts' scope or commercial value were disclosed.
AIS data shows the two vessels are currently berthed on the west coast of Norway.
During the past few weeks, Viking Queen has been repositioned to Bergen from the eastern Mediterranean, according to AIS tracking data.
Viking Queen appears to have been employed since mid-February in supporting Saipem vessels at the Zohr Field Development Project, the largest offshore gas project in the Mediterranean, AIS data shows.
Meanwhile, the Havila Clipper appears to have been at work since late March at Equinor's Oseberg Field Centre in the North Sea, around 130 km north-west of Bergen, according to AIS data.
