The M/S Høydal, will be the world’s first LNG-powered coaster, was built at the Tersan Shipyard, Turkey for NSK Shipping, Norway. The 2,650 dwt vessel has an LOA of 230 ft (70 m) and will be powered by a single Rolls-Royce Bergen C25:33L6P engine rated at 1,650 kW at 1,000 rpm operating on LNG. Propulsion is by a Rolls-Royce CP propeller and the maximum speed is 14 kn. The is a 3,200 ct ft (90 m3) LNG tank on board and refueling is planned to be supplied from a permanent bunkering facility near the charterer BioMar’s factory, once a week. Natural gas (LNG) propulsion will make the vessel environmentally friendly and reduce emissions of NOx (nitrogen oxides) by over 90 per cent. [More]

Nor Lines the Norwegian logistics and shipping company has ordered two liquefied natural gas (LNG) fueled cargo vessels of 5,000 dwt with an option on two further vessels, at Tsuji Heavy Industries (Jiangsu) Shipyard, China. The ship is a Rolls-Royce Marine design for a mixed cargo vessel and follows an Environmental Ship Concept (Environship) presented at the this year’s Nor-Shipping Exhibition and Conference and winning the Next Generation Award. The vessel has an LOA of 394 ft (120 m) and uses a Bergen B Series lean burn gas engine type B35:40 V12 developing 3,930 kW (5,268 hp) at 750 rpm. A Hybrid Shaft Generator (HSG)system is specified, reducing the need to run auxiliary gensets. The shaft generator can also operate as a power take-in motor thereby providing redundancy for the propulsion system. [More]

Austal Ltd, has just completed an 18 month study on the development of several new types of fast ferry. Their study concluded that the most promising solutions for future regulations are multi-hulled HSC code compliant ferries running at a significantly slower speeds than present fast ferries. Austal gives three examples of new designs using LNG as the main fuel. The largest example is a 127 m trimaran ferry powered by twin dual fuel GE LM2500 gas turbines. A smaller 102 m trimaran ferry uses three 4 MW Wärtsilä 9L34DF dual fuel, medium speed engines. The smallest design example is a 72 m catamaran ferry using a dual fuel diesel/LNG electric propulsion system of four 2.3 MW Bergen dual fuel engines. [More]
