Marine Diesel Engines – Exhaust Gas Emissions – Paying a Price

Marine Diesel engines have a remarkable ability to work with a variety of fuels, ranging from Heavy Fuel Oil (HFO) to Liquid Natural Gas (LNG) as well as a range of distillates of refined crude oil in between. Not surprisingly the ship-owner's fuel of choice for large two-stroke Diesel engines over the years has been HFO, the low-price by-product of oil refinery output. Onboard fuel oil treatment being taken care of by purifiers/calorifiers prior to fuel injection, and more recently by advanced computer driven fuel cleaning systems.Unfortunately HFO is high in nitrogen, sulfur and ash, greatly increasing the NOx and SOx content in marine Diesel engine exhaust gas emissions, a fact which has led pollution control agencies worldwide – IMO, EU and other, localised, Emission Control Areas (ECA) –  to set progressively exacting limits in revised MARPOL VI.A bleak future for ship-owners who were not already planning for year 2015 (when sulfur limits in the ECA's will be rest...

Dual Fuel Marine Diesel Engines – LNG & MDO – the Way Ahead?

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]

Fantastica, a cruise ship of some 133,500gt, due to be constructed  for MSC Cruises by STX Europe in their St Nazaire shipyard will carry 4,874 passengers and crew, whose healthy thirsts will be quenched by means of Multi Stage Flash (MSF) evaporation systems to be supplied by Hamworthy Serck Como.The demand for fresh water by such a large floating population is obviously huge, but according to Hamworthy Sales Director Udo Attermeyer on 21,October 2010, the two Hamworthy MSF 950-8 MSF units on order for Fantastica are capable of delivering 950 tonnes of water per day for a variety of on-board purposes including potable drinking water that measures up to WHO standards. Farewell to fresh water bunker hoses snaking aboard!It may be helpful to sum up MSF technology in a few words for those unfamiliar with the system.  Feed water is heated in one compartment before being released into a second chamber in which the pressure and the temperature is substantially lower, causing a 'fla...
