Environmentally Sound Technology

GE Marine Engines will install LM2500+ aeroderivative gas turbines in Combined Diesel And Gas (CODAG) turbine configurations on four Grand Princess-class cruise ships currently on order from Princess Cruises.

One LM2500+ gas turbine will be used on each vessel in conjunction with medium-speed diesel enginedriven alternators.

Mitsubishi Heavy Industries Ltd. (MHI) will construct two 113,000-ton cruise ships at its Nagasaki, Japan shipyard. Each ship will use four diesel enginedrive alternators. Chantiers de l'Atlantique will build two 88,000-ton vessels at its facilities in Saint Nazaire, France, each of which will use two diesel engine-driven alternators.

The Mitsubishi-constructed vessels are the largest cruise ships ever ordered by Princess and the first to be commissioned from MHI. All four Grand Princessclass ships are part of a five-year expansion program that will see the Princess fleet grow to include 14 ships carrying more than 1.5 million passengers annually.

According to Princess Cruises, the diesel and gas turbine propulsion arrangement employs environmentally sound technology that supports their ongoing commitment to this important issue. At the same time, this design incorporates better space usage through installation of the gas turbine in the funnel area of the ships, thereby enabling an even wider range of public rooms and onboard facilities to be introduced.
