LONDON – Rolls-Royce Commercial Marine will deliver five engines and four large UUC thrusters to power a new semisubmersible drilling rig to be built by Keppel FELS in Singapore for Awilco Drilling.

The Moss CS 60 Eco MW design rig, targeted at harsh environments, will be equipped and certified for drilling on the Norwegian continental shelf, including in the Barents Sea, in water depths up to 5,000 ft (1,524 m).

It is scheduled for delivery from Keppel FELS in 2021.

Claus Mørch, project director, Awilco Drilling, said: “This will be the most environmentally friendly drilling rig offered in the harsh environment market, and the first rig on the Norwegian continental shelf that answers to the Tier 3 requirements.”

Rolls-Royce will supply five B33:45L8A diesel engines and four UUC high torque thrusters (3.8 MW).

The scope of supply includes the five main generator sets, fully classed as emergency generators; other generators; a heat recovery system, air intake silencer and filter system.

The newly developed UUC 355 HT thruster is said to provide a high thrust with a low power input on the thruster.

These thrusters, in combination with the efficient Bergen diesel engines, should lead to low fuel consumption, low emissions and an optimized electrical load balance on the rig, Rolls-Royce claimed, adding that its certified condition-based monitoring system should also bring Awilco operational savings.
