Rolls-Royce has won contracts worth $136m to supply technology and support services to Dolphin Energy, which transports natural gas from Qatar to the United Arab Emirates and Oman via a 364 km subsea pipeline.

Rolls-Royce will supply Dolphin Energy with three industrial Trent gas turbine compression packages. The three units, each rated at 52 MW, will join six similar Rolls-Royce units that went into service at Dolphin Energy’s gas processing plant in Ras Laffan, Qatar, in 2006.

The equipment will be manufactured at Rolls-Royce’s facilities in Montreal, Canada, and Ohio in the US, with delivery to Ras Laffan set for the middle of next year.

Andrew Heath, Rolls-Royce energy president, said: “I am delighted that Rolls-Royce technology has again been selected to support the Dolphin Gas Project, one of the largest cross border energy infrastructure projects ever undertaken in the Middle East.”

He added that to date the six units already installed on the Dolphin Energy project had recorded over 150,000 operating hours.
