Rolls-Royce's milestone 100th contract is to deliver drillship propulsion systems to a Transocean rig. In recent months Rolls-Royce has won orders to supply propulsion systems for seven new drillships totaling close to £100 million, including options, from a variety of customers including Transocean. These ships will be built in the Samsung, Daewoo and Hyundai shipyards in Korea. Rolls-Royce is a leading supplier of large thrusters to these specialist vessels, with a market share in excess of 70 per cent.
