Rolls-Royce to supply electric propulsion to ice-class superyacht

Rolls-Royce has won a contract to provide electric propulsion and power electric systems for a new ice-classified superyacht, the 70m King Shark, being built in Viareggio by Italian yacht company Rossinavi. Rolls-Royce’s electric propulsion technology will enable the vessel to travel up to 6,000 nautical miles at 12kts and to reach a top speed of 17kts. The company’s SAVE Cube system allows the engines to be operated at variable speeds, increasing efficiency and reducing fuel consumption in the different operating conditions. Placing drives, frequency converter and switchboard in a single cabinet also allows easier installation and saves space. The company is also supplying two Azipull AZP085 azimuthing thrusters. This combination of low-drag body and pulling propeller gives a high propulsive efficiency and enhanced manoeuvrability, together with course-keeping ability. Rolls-Royce is also supplying a dynamic positioning system for the yacht, providing a dynamic anchoring capability that will hold the vessel in position to counteract the effects of both wind and wave. Gary Nutter, director, products – marine, Rolls-Royce, said, “Our experience of designing and building high-technology equipment for the most advanced vessels has allowed us to help Rossinavi identify the optimum combination of systems the King Shark needs to operate in Arctic conditions efficiently, safely and comfortably.” King Shark, which is due to be completed in 2021, has been designed by Team for Design, a yacht design and architecture firm based in Venice, Italy, to cruise both warm and freezing waters. Naval architecture is by Arrabito Naval Architects and the yacht will be certified under RINA and Lloyd’s Register. It is equipped with amenities such as a soundproof cinema room, fully equipped gym, spa and massage room, and owner cabin with large private terrace and round pool.
