The NVC 256 will carry passengers and vehicles and is the latest ship design from the Rolls-Royce Environship range, incorporating a variety of features to reduce environmental impact while increasing efficiency, including an engine powered by LNG.
The new ferry concept will incorporate a Rolls-Royce solution including systems, equipment and ship design. This includes Bergen engines, a wave piercing bow and a Promas propulsion system which combines a propeller and rudder, reducing drag and enhancing manoeuvrability.
Another feature of the propulsion system is the Rolls-Royce Hybrid Shaft Generator (HSG) which produces electrical power from the propulsion engines instead of running auxiliary diesel generators. This optimises on board power generation, cutting fuel consumption and exhaust emissions.
This is the latest in a series of recent wins for Rolls-Royce LNG powered ships, which includes the world’s first gas powered tugs, coastal cargo ships and passenger ferries. The world’s first LNG powered cargo ship, powered by Rolls-Royce, entered service in Norway earlier this year.
Key facts about the Environship:
• The Rolls-Royce Environship concept, received the prestigious Next Generation Ship Award at the 2011 NorShipping event in Oslo, Norway.
• The Rolls-Royce Bergen B&C Series lean burn gas engines, as used in the Environship, emit around 22 per cent less CO2 (per unit of power) than a diesel engine.
• The use of gas fuelled engines means that Nitrogen Oxide (NOx) emissions are reduced by about 90 per cent while Sulphur Oxide (SOx) emissions are negligible.
• These emissions are already within the limits of IMO (International Maritime Organisation) Tier III environmental legislation, due to come into force in 2016.
• The Rolls-Royce Promas propulsion system is an integrated rudder and propeller, which alone improves efficiency of the vessel by 5 to 8 per cent.
• The new innovative bow shape and hull form, designed by Rolls-Royce, also reduce resistance by up to 8 per cent, therefore reducing fuel burn and emissions further.
• The vertical bow shape enables the vessel to maintain speed even in rough seas enabling operators to achieve demanding shipping schedules without the need to burn additional fuel to make up lost time.
• Rolls-Royce Hybrid Shaft Generator (HSG) optimises on board power generation, cutting fuel consumption and exhaust emissions.
