GE Marine completes fire testing on LM2500
GE’s Marine Solutions has successfully completed fire testing on its new composite LM2500 marine enclosure as part of the Module Modernisation Program (MMP), the company announced on 30 May.
The fire testing validates that the composite design meets US Navy fire resistance requirements.
The MMP programme is designed to inject updated technologies into the gas turbine module that reduce enclosure weight by approximately 50 percent, while also reducing life cycle costs, noise emission and improving safety.
The new LM2500's composite structure does not use bolted joints between the walls and ceiling. This improves assembly and noise attenuation through the elimination of noise channels. With the use of composites, the module doors and access panels can be made larger, yet lighter for easy handling. The use of composites also eliminates rusting of doors, hinges and access panels, reducing maintenance and improving safety.
A prototype enclosure is currently being assembled to be tested in a full-scale gas turbine test cell to validate noise attenuation and thermal performances. The composite enclosure will then be subjected to barge shock testing to US Navy requirements. These tests are expected to be completed by mid-2018.
The gas turbine module developed under the MMP programme will be available in 2018 on the US Navy’s DDG-51 Flight III ships.
