HOUSTON, Texas- GE Industrial AeroDerivative Gas Turbines (GE-IAD) announced that the low pressure turbine of an LM2500 aeroderivative gas turbine recently surpassed 100,000 operating hours without removal.

The LM2500 has been in service on Statoil's Statfjord C offshore platform in the Norwegian sector of the North Sea since July 1985. The LM2500's low-pressure turbine, initially installed when the unit was commissioned, is still operating virtually trouble-free.

"The Statfjord unit is further testament to the outstanding reliability of the LM2500," said Rick Felini, GE-IAD's product line manager. "In fact the worldwide fleet of LM2500s -- which is some 1,500 engines strong - continue to perform extremely well. Reported 12-month fleet availability and reliability is 98.3% and 99.6% respectively in a variety of power generation and mechanical drive applications."

Statoil has a total of 17 LM2500 gas turbines on the Statfjord A, B and C platforms. The gas turbines are used for compressor drives and provide the electrical load on the three platforms, which began production in November 1979, November 1982, and June 1985, respectively.

Statoil also has the largest industrial fleet of LM2500s in the world, totaling 44 gas turbines which have accumulated 2.75 million hours in service on various North Sea platforms.

LM2500 Improvements

GE has increased the performance capability of the LM2500 from its introductory rating of 17.9 megawatts to the present 29 megawatts for the LM2500+. These improvements have been made possible through the continuous incorporation of state-of-the-art materials, coatings and components into production LM2500s.

GE-IAD is part of GE Power Systems, and is headquartered in Evendale, OH. GE-IAD is the world's largest designer, developer and manufacturer of aeroderivative gas turbines for a variety of power generation and gas compression applications.
