This single tank LNG system has got full gas redundancy i.e. no diesel back up is required. The vessels will also be equipped with two Rolls Royce azimuth propellers.The operational benefits of a gas fuelled propulsion system are a cleaner engine room, less waste oil and no “switch over” problems. Environmental benefits of S.I. gas engines, incorporated in the new design, are:92% reduced NOx emission17% reduced GHG emission98-100% reduced SOx emission98% reduced particulatesCompliant with Tier III regulationsAlso, the new hull and propulsion system will achieve up to 20% higher thrust efficiency compared to standard designs.The vessels have the following specifications:Loa: 38.00mBm: 14.50mDraft: 7.50mBollard Pull 65 tonnesAccommodation for 5 persons
