ExxonMobil is closing down tanker vetting division IMT and handing all ship vetting over to Maritime Global Services, a new Glasgow-based arm of the Stena group's Northern Marine Management.

Singapore-based IMT is the former in-house tanker owning entity International Marine Transportation, which became an in-house tanker vetting operation when ExxonMobil got out of shipowning.

The move is long-planned.
