Rolls-Royce congratulated the Norwegian Ship Owner and Ferry operator Fjord Line on the environmental efficiency award presented to the two passenger ferries Stavangerfjord and Bergensfjord during the Nor-Shipping exhibition in Oslo.
The two ferries will be the first international service passenger ferries in the world to run on pure LNG engines. Both vessels are equipped with LNG based power and propulsion systems delivered by Rolls-Royce. This includes four Bergen gas engines for each vessel, powering a highly efficient Promas integrated rudder and propeller propulsion system. The vessels are currently in the final stages of construction at Bergen Fosen shipyard.
The use of gas fuelled engines means that Nitrogen Oxide (NOx) emissions are reduced by about 90% while Sulphur Oxide (SOx) and particulates emissions are negligible. These emissions are already within the limits of IMO (International Maritime Organization) Tier III environmental legislation, due to come into force in 2016.
