Rolls-Royce has revealed a luxury yacht concept Crystal Blue, that was designed to demonstrate the advantages of advanced ship intelligence solutions and hybrid propulsion based on LNG fuel and battery power in the marine leisure market. The new project and its attendant support vessel Blue Shadow have been developed to enable new thinking in yacht design and propulsion by optimising the yacht’s super structure for greater guest use and comfort.
With the help of an intelligent dynamic positioning system, which automatically controls twin azimuthing thrusters and a TT1100 bow thruster, Crystal Blue will remain in the right spot on the water, without using an anchor. The yacht is fitted with new safety feature. Dubbed “safe room”, it allows guests and crew to seek refuge in the event of an unauthorised boarding. Once inside, the crew can override the controls and operate the yacht remotely or direct a shore-based centre to pilot the vessel.
Designed for 12+ passengers and 12 crew, the 62 metre Crystal Blue is based on a composite or aluminium hull operating a power plant based on the Rolls-Royce hybrid LNG/Battery SAVe-CUBE system configuration.
The machinery consists of twin LNG-fuelled 16V4000 MTU M65-N generator sets working in parallel with a battery bank to provide 1MWh of genset-free power during port stays. Two low-weight carbon Azipull thrusters provide propulsive power to achieve maximum service speeds of 20 knots.
