The liftboats offer comprehensive support for drilling, workover, stimulation, and completion operations by providing good accommodations space, good cargo-handling capacity, and operation flexibility. The self-propelled liftboats are outfitted with advanced propelling and navigation systems and high-tonnage hoisting equipment positioned to take advantage of their large open-deck spaces.
The accommodation rigs, COSL RIGMAR (jack-up) and COSL RIVAL (semi) are currently stationed in the North Sea.
