Eight or ten
Sauter Carbon Offset Design (SCOD) unveiled the design of its largest and most eco-friendly luxury yacht, in March 2012. The Ocean Supremacy has a top speed of 55kt and is expected to rank among the top ten fastest super-yachts in the world.
She is designed to consume 50% less fuel than other similar yachts and provide zero carbon cruising at 14kt speed. British designer Richard John Sauter of SCOD is the main architect of the yacht.
The Ocean Supremacy is 42m long and has a beam of 15.6m and a draft of 1m. She will be built with marine grade aluminium or carbon epoxy composites. She will have a fuel capacity of 45,000l. The super-yacht can accommodate ten guests and will be served by eight to ten crew members.
The yacht will have a low wave signature and high efficiency wave-piercing tank tested hulls. Ocean Yacht Systems will supply its rim driven bow thruster for GP mooring.
Maritime Dynamics (MDI) will provide its retractable t-foil leveling system to be positioned at the aft end. The ship will use SCOD tested wind tunnel aerodynamic radome and PV wing spoilers for efficient aerodynamics.
The wind tunnel and foils at the stern will allow lamina flow between bow to stern and reduce the drag and turbulence associated with conventional super-yachts. OceanLED lighting, energy star rated AC, refrigeration and other equipment with waste heat recovery will be used.
The super-yacht can cruise unlimited range with zero carbon cruising at 14kt. She has a cruise range of 3,600nm at a speed of 18kt in solar hybrid and carbon neutral cruising.
The upper deck sprawling, the entire beam of the yacht, will house the Master Suite. It will have a king-size bed, a three-seater sofa, a double whirlpool-equipped en-suite bathroom, dressing room and vanity table, flat screen television, Wi-Fi, film and music library. The suite will have an office and provide panoramic views.
Four guest cabins of the super-yacht will be provided with queen-size beds, flat screen TVs, Wi-Fi, a film and music library, arm chair, desk, vanity table and en-suite bathroom with whirlpool.
The main deck of the ship will have a sundeck with a pool area and can be used for various activities, such as parties, events and entertainment. A photovoltaic canopy protects the cockpit outside the upper deck from sun and rain. A retractable giant flat screen on the deck can be viewed by 20 guests as an open-air outdoor cinema.
The Ocean Supremacy will be powered by a 9MW solar hybrid propulsion system. It will utilise a combination of different sustainable power sources – solar, biomass diesel, wind energy and wave strengths – for environmentally friendly propulsion.
A marine solar cell array of 70kW from SunPower Solbian will be installed on the yacht to charge the UPS. The Lloyds approved UPS will also act as a power booster.
A 200kW auxiliary inflatable traction kite from SkySail will also allow for zero carbon cruising. The wind powered system will be used to charge batteries or increase the cruising speed.
A 50kW motion damping regeneration (MDR) system from Maurer Sohne will use energy from waves. It will either charge the batteries or increase the cruising speed of the super-yacht.
The propulsion system also includes 2X V16 series 2000 Tier 4i MTU Genset. Each unit will generate 1MW and will be capable of using biodiesel. One power unit can be used in conjunction with the solar, wave and wind power to achieve a hybrid cruising speed of 18kt. It will be the most economical and eco-friendly propulsion system.
Ocean Supremacy will also have four V16 Series 2000 Tier 4i MTU or ZF Hybrid Motors. Each of the power units will generate about 1.5MW, allowing a cruising speed of about 45kt. The generating units will also be compatible with biodiesel.
A 2MW Lloyds approved Corvus Lithium Polymer uninterruptible power supply (UPS) or two V16 Tier 4i MTU Gensets will power two 1.5MW Siemens supplied electric motors. They will drive two retractable Anerson ASD 10 Surface Drives, located in the demi-hull to propel the yacht at speeds of about 53kt. Two 1.5MW Kamewa S3-125 series water-jet propulsion drives from Rolls Royce will also be equipped in each of the two wave-piercing hulls of the yacht.
The water-jets will be driven with parallel MTU or ZF hybrid motors, also powered by the UPS or the 1MW Tier 4i MTU Gensets.
The yacht can cruise even after shutting down any of its six diesel engines to further reduce the consumption rates. The renewable energy sources are expected to reduce the associated green house gas emissions by 50%.
The hybrid green power will also cut the CO2 emissions of the Ocean Supremacy by 4,000t. She can generate and supply about 200MWh of electricity when plugged in to the onshore grid.
