LM2500+ Marine Engine

Cruise ships typically chart a course for environmentally pristine areas. That's just one reason we believe the engines powering them should have minimal impact on the surrounding environment. The LM2500+ is GE's latest aeroderivative gas turbine engine driving toward a cleaner future.

With the LM2500+ marine gas turbines powering cruise ships, GE brings ecomagination to the high seas and helps reduce environmental impact to ports around the world. Thanks to the highly efficient combustion process and the quality of fuel used in the LM2500+, these marine engines help preserve the natural beauty of the places they visit.

As an aeroderivative engine, the LM2500+ marine engine benefits from the same high-tech materials and designs that help make GE aircraft engines some of the most advanced in the world. With the use of lightweight materials and the inherent power density of aero gas turbines, the LM2500+ weighs up to 74 percent less than a comparable diesel engine and occupies roughly one-third of the space.

Noise and particulate emissions are also greatly reduced compared to diesel engines. Nitrogen oxide, sulfur dioxide and particulates are reduced from 60 percent to 90 percent while perceptible noise is roughly one-fifth.

On a typical trans-Atlantic cruise, a ship powered by LM2500+ gas turbines would operate far more cleanly than a comparable ship powered by diesel engines - reducing particular matter emissions by 4,200 pounds (62 percent less), nitrogen oxides by nearly 169,000 pounds (67 percent less), and sulfur dioxide by 259,000 pounds (93 percent less).

If a typical cruise ship, powered by diesel engines, were to make a single trip around the world, it would produce the following:

» 380 tons of nitrogen oxide

» 9 tons of particulate matter

» 370 tons of sulfur dioxide

If a comparable ship powered by LM2500+ gas turbines made that same trip, it would produce the following:

» one-third of the nitrogen oxide

» less than one-half of the particulate matter

» one-fifteenth of the sulfur dioxide

In some of the more pristine ports around the world, the production of sludge and smoke is severely regulated. These ports welcome ships powered by LM2500+ engines because they are virtually sludge- and smoke-free. A typical diesel-powered cruise ship emits visible smoke and produces more than 500 tons of sludge per year, making the LM2500+ a clear choice indeed.

While we think this engine is pretty special, other international agencies agree as well. The United States Coast Guard, Lloyds Register and Lloyd's List have all recognized LM2500+ cruise ship operators with environmental excellence awards for their contributions in moving toward a cleaner world.
