Twelfth support vessel enters service: MV Ameristar Cutline
An oil spill response vessel completes the marine fleet at twelve vessels — every one a different class, every one ordered new.
MV Ameristar Cutline, a 58 m oil spill response vessel with 1,200 m3 of recovered-oil capacity, was accepted at Venice, Louisiana and entered service this week.
She is the twelfth and final vessel of the planned marine fleet. The fleet deliberately contains no two vessels of the same class: platform supply, deepwater supply, fast supply intervention, emergency response and rescue, anchor handling tug supply, multipurpose support, well intervention, dive support, self-elevating liftboat, survey and ROV support, crew transfer, and spill response.
Twelve classes cost more to crew and maintain than twelve of one class. The company took that cost so it does not have to charter in a capability at the moment it needs it most.
