Swire Pacific Offshore has awarded Rolls-Royce a £50m ($80.6m) contract to supply advanced anchor handling systems for four offshore vessels currently under construction in Singapore. The systems are developed for the safer handling of large anchors on deck, such as the torpedo anchors used in the deepwater oil and gas fields off the coast of Brazil. Rolls-Royce will supply a complete deck machinery system to each of the four vessels, which are being built at ST Marine's shipyard. The system is equipped with a low pressure hydraulic winch for anchor handling and towing, with a pulling capacity of 500 tonnes driven by eight motors. Arne Tande, senior vice president of offshore deck machinery at Rolls-Royce, said the contract with Swire demonstrates its continual focus on research and development, and advancements in the technical capabilities of its products.
