The Coral Adventurer has been designed to bring together our 34 years of experience building and operating expedition ships with some of the latest advances in marine and environmental
technology. Here are some fast facts for those curious about what is below the decks:
POWER AND PROPULSION
Coral Adventurer is powered by two Rolls-Royce Azipull thrusters that enable the central propulsion of the vessel. The thrusters work as both propellers and rudders, which maintain excellent maneuverability at slow speed when anchoring in remote locations or coming into port. They offer both high hydrodynamic and fuel efficiency along with low noise and vibration levels.
WATER SUPPLY AND TREATMENT
Two state of the art reverse osmosis water generators can produce more than 100,000 litres of fresh water per day. Approximately half of this volume is used daily when we operate with a full complement of passengers and crew, leaving excess fresh water to share with drought-affected village communities on our voyages. The vessels’ grey water is treated through a high-tech onboard processing plant.
DIESEL ELECTRO PROPULSION
Three diesel generators are onboard. Two 1360 kW generators and one 940 kW generator are used in variable configuration to allow optimal operation and fuel efficiency throughout the voyage. In other words, the Coral Adventurer only produces as much power as is required at any time, and this is accomplished by having the configuration and output of the combined generators running at synchronised levels matching the needs at the time of day/night. For example, at anchor we can operate on the 940-kW generator at between 50-70% load. If we are steaming slowly, we can add one large generator to the small generator or run both large generators. This way, we can operate the engines at optimal efficiency of approximately 70%. The mechanical engine that runs the generator is a Caterpillar and the propulsion system itself is Rolls Royce.
