GE seeks ABS certification for LM6000
GE Transportation's marine gas turbine business has launched a program to obtain American Bureau of Shipping (ABS) certification, to the Steel Vessel and the new Naval Vessel Rules, for its LM6000 aeroderivative gas turbine.
GE plans to certify the LM6000 at a power level greater than 36 megawatts based on United States Navy standard day conditions (100oF).
LM6000s have accumulated more than 290,000 hours on floating, production, storage and off-loading vessels, and aboard commercial power barges and offshore platforms, according to Karl Matson, general manager of GE Transportation's marine business, Evendale, Ohio. The engine is already certified for commercial use by Det Norske Veritas (DNV).
By adding the ABS certification to its profile, the LM6000 will be eligible for several next-generation naval programs that require electric and mechanical drive service such as the U.S. Navy's DD(X) program.
GE expects to complete the testing program and receive ABS certification in 2005.
The ABS certification process includes endurance tests to demonstrate operation in electrical power generation and mechanical drive modes; engine tear down after final endurance test; and preparation and submission of inspection report to ABS.
The LM6000 was introduced in 1990, and, says GE, has become the most efficient simple cycle gas turbine in its class, with an efficiency of 41.9 percent at the ISO rating point.
All of the 590 industrial LM6000 gas turbines in operation drive electric generators, accumulating nearly nine million hours in service with a fleet wide reliability of 99.9 percent.
The LM6000 is the high power member of the GE LM aeroderivative gas turbine offerings.
The powerful LM6000 marine gas turbine can be coupled with an electric generator making an LM6000 marine gas turbine-generator set. GE furnishes the complete marinized LM6000 gas turbine-generator set using a generator selected based on customer requirements.
GE says it has investment and technical plans to take the LM6000 well beyond its current rating without increasing the engine's shipboard size and weight footprint..
