The LM2500+ marine gas turbine is based on the design of the industry-leading GE LM2500. This machine delivers up to 20% more power at a simple-cycle thermal efficiency greater than 39%. It is also designed to achieve the precedent-setting reliability of its parent. It has been used aboard the US Navy's LHD 8, two high-speed ferries, eight cruise ships, and the Queen Mary 2 cruise liner.
|
|
|
The LM2500 marine gas turbine is GE's most widely applied gas turbine. It powers more than 400 ships in 30 world navies, fast ferries, coast guard cutters, supply ships and cruise ships.
|
|
|
The LM6000 is the most fuel-efficient simple-cycle gas turbine in its size class today, delivering more than 40MW at over 40% thermal efficiency. It is in use on FPSOs and offshore platforms in marine environments and has been proposed for military ship applications.
|
|
|
A derivative of the F404 turbofan fighter engine, the LM1600 is the most fuel-efficient, simple-cycle, gas turbine in its power class. It has powered high-speed ferries and high-speed yachts.
|
|
|
The LM500 marine gas turbine is derived from the GE high efficiency TF34 turbofan engine and incorporates many of the same materials as those proven on the highly successful LM2500 marine gas turbine. More than 100 engines power military patrol boat and commercial fast ferries.

The basis for Aalborg Industries Inert Gas Systems' success and strong market position was the development of a unique low-oxygen oil burner, which was patented under the name of Ultramizing burner®. In this System the oil is atomized in an ultra-fine dispersion pattern using the combustion air for atomization. This features a highly-efficient, two-stage, oil/air mixing technique, which results in an oxygen content of less than 0.1% volume and absolutely without any soot formation.

The NR/S basically follows the advantageous design principle of the NA/S series, only equipped with a radial turbine instead of an axial turbine. By the comparably simple design of the cast radial turbine, the NR/S series becomes the most economical choice for heavy fuel oil engines in the wide range from 450 kW up to 5 400 kW engine output per turbocharger without any compromise in reliability and performance.
For engine outputs from 450 to 5 400 kW per turbocharger
