LM9000

LM9000
aeroderivative
gas turbine
(67 MW 50/60 Hz)

Text

The most competitive gas turbine in the 65+ power range



LM9000

Highest availability, and best-in-class total cost of ownership in its power class

The LM9000’s DLE technology enables dual-fuel capability, and reduces NOx emissions while eliminating water use in emissions abatement.



Benefits

  • 43% efficiency in simple cycle, 80% in cogeneration
  • Higher availability thanks to long maintenance intervals, and modular package allowing 24-hour engine swap
  • Pressurized LNG compressor startup capability without helper motor assistance

Features

  • Powerful and efficient gas turbine derived from the GE90-115B on Boeing 777s since 2004
  • Modular package enables faster installation, and lower installed and operational costs than field-erected units
  • Compact package is ideal for stringent space requirements, especially retrofits and new small plants
  • Designed for easy inspection and condition-based maintenance—delivering high reliability and maintainability

Mechanical drive performance

  • Power: 67 MW
  • Efficiency: 43%
  • NOx emissions: 15 ppm
  • Exhaust temperature: 455°C
  • Exhaust flow: 184.5 kg/s
  • 100% output speed: 3,429 rpm
  • Maintenance intervals (hours): 12,000 for borescope, 36,000 for hot section replacement, 72,000 for overhaul

​​​​​​​At ISO conditions with natural gas fuel, ambient temperature 15ºC, no inlet or exhaust losses, sea level, 60% relative humidity.

Power generation performance
(50–60 Hz)

  • Power: 66.5 MW
  • Efficiency: 42–42.4%
  • NOx Emissions: 15 ppm
  • Exhaust Temp: 456°C
  • Exhaust flow: 187.6–184 kg/s
  • 100% output speed: 3,000–3,600 rpm
  • Maintenance intervals (hours): 12,000 for borescope, 36,000 for hot section replacement, 72,000 for overhaul

At ISO conditions with natural gas fuel, ambient temperature 15ºC, no inlet or exhaust losses, sea level, 60% relative humidity.

Physical specifications

  • Package dimensions: 13.3 x 5 x 18.2 m (LxWxH)
  • Engine dimensions: 7 x 2.5 m (LxW) including support structure and piping
  • Engine weight: 17 t

Applications

  • New and retrofit LNG
  • Power generation (including simple cycle, cogeneration, and combined cycle)
  • Onshore
  • Offshore


Power and speed flexibility

A key design feature is its free power turbine—enabling high-efficiency power and speeds over a wide range of ambient conditions.

Optimized package design

Its modular package design enables shorter manufacturing cycles and faster installation; and its compact footprint helps to meet stringent space requirements.

Maintenance and cost advantages

The LM9000 helps reduce CAPEX in LNG—no need of a helper motor and the longer maintenance intervals help to reduce OPEX.
