Rolls-Royce recently announced that BG Group has selected the Trent 60 DLE industrial gas turbine as the driver for the main refrigeration compressors in the proposed Lake Charles LNG Export project in Louisiana, USA. The two companies have also signed a Long Term Service Agreement covering the support and maintenance of the equipment for up to 25 years. Both the equipment and service contracts are expected to be activated in the first half of 2015, subject to the US LNG plant permitting process and final investment decisions by BG Group and Energy Transfer, the developers of the project.
Each of the three LNG trains will utilize four Trent 60 DLE gas turbines as part of the Air Products C3MR refrigeration process. Each train will employ two Trent 60 DLE gas turbines driving propane compressors and two Trent 60 DLE gas turbines driving mixed refrigerant compressors for a total of twelve Trent 60 DLE gas turbines in the plant.
Based on aero Trent 800
With an ISO rating of 54.2 MW and 43.6 percent thermal efficiency, the Trent 60 DLE, which is based on the aero Trent 800 with over 20 million operating hours, is considered the most powerful and fuel efficient aero-derivative gas turbine available. With over 300,000 hours of experience in mechanical drive, a compact plot plan and field proven extremely high levels of availability and reliability, the Trent 60 is ideal for both onshore and offshore LNG facilities.
Andrew Heath, President of Rolls-Royce Energy said, “We’re delighted with BG Group’s vote of confidence in the Trent 60 DLE. We believe our aero-derivative technology will become the leader in the LNG sector, due to its superior economics. We are looking forward to a long and productive relationship with BG.”
