Coral Princess’ propulsion system is the first in the cruise industry to fully utilize a new development of the diesel engine known as an EnviroEngine, as well as the first in the Princess fleet to incorporate gas turbine power generation. This combination uses technology proven to be both highly efficient and environmentally sound, and, in a unique design development where the gas turbine is installed in the ship funnel, provides additional space for a wider range of public rooms and onboard facilities.
Coral Princess is powered by one gas turbine that operates in conjunction with two diesel EnviroEngines. The turbine replaces at least two diesel engines and by using two separate power systems, this unique one-of-a-kind configuration creates a very reliable and safe energy source.
Described as the most environmentally friendly and economical way of using fossil fuel for power production, the EnviroEngines, manufactured by Wärtsilä, were developed in close cooperation with P&O Princess Cruises. Representing state-of-the-art diesel engine technology, EnviroEngines employ common rail fuel injection technology that results in smokeless operation, producing a clear engine exhaust and direct water injection to reduce NOx.
