France’s Brittany Ferries has ordered a huge 210-m long, 52,000 gt, almost 2,500 passenger capacity, dual-fuel cruise ferry that they claim will be the first in UK waters to use natural gas to power its engines. At the same time they claim it will be first in the world to employ technology that allows the fuel to be carried on board at close to atmospheric pressure.

STX France explains that the ship bears the self-explanatory code name PEGASIS (Power Efficient Gas Innovative Ship) and is one of 34 projects engaged in the ‘New Industrial France’ programme. According to Brittany Ferries four dual-fuel engines (natural gas and marine diesel oil) will be installed (they do not choose to name the engine builders at this stage) with a total installed power of 45 MW and LNG bunker capacity of 1,300 cu.m.Clearly, much forward bunker safety and logistical planning was needed, and Brittany Ferries say that t...

Marine Diesel engines, thanks to enormous technological strides in the past few decades, have proven themselves powerful, reliable and efficient, to the extent that by year 2000 motor ships composed no less than 98% of the merchant fleet. Despite these plaudits, regulatory bodies continue to penalise the Diesel engine for exhaust gas emissions inherent in a combustion process using Marine Diesel Oil (MDO) fuel that almost always leaves by-products of oxides of nitrogen, unburned hydrocarbons, and carbon monoxide in the exhaust smoke.Environmentalists have the expectation that technology will solve all political and economic problems, and will not be disappointed to hear that developers have succeeded in harnessing low emission Liquid Natural Gas (LNG), a clean fuel with lean burn combustion characteristics, to power the engine invented by Rudolf Diesel in 1897. Many analysts confirm the recent prediction of Klaus Deleroi, Senior V-P, MAN Diesel & Turbo SE, that: "When it come... [More]
