Unique Propulsion System


Unique Propulsion System

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. The gas turbine is installed in the ship funnel, which frees up 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 configuration creates a 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. The engines employ common rail fuel injection technology that results in smokeless operation, producing a clear engine exhaust and direct water injection to reduce NOx.Princess is also the first cruise line to install a gas turbine in its ships’ funnel; a positioning that creates a technological challenge. This unique placement frees up significant additional passenger space – used to incorporate more public features into the ship’s design. As a result, Coral Princess passengers will enjoy the benefits of two lower decks dedicated to public amenities where most other ships offer only one.

Gas turbine-generator packages used aboard Coral Princess are specially designed to be lightweight and inherently create low visible exhaust emissions and minimal oil waste. In addition, the design of a gas turbine allows highly effective isolation of noise and vibration.
