Low Cost Fuel Oil Alternative: Development on Track

A new low-cost alternative to heavy fuel oil recently came successfully through further tests on the 2-stroke marine diesel engine of a Maersk Line container ship, an engine fairly typical of a type to be found on modern ships.  The tests were carried out in late 2012 by A.P.Møller-Mærsk and a leading marine engine manufacturer.

In 2004 a long term alliance agreement was established with AkzoNobel, a world leader in surface chemistry.MSAR® Fuel Techn... [More]

Marine Diesel Engine Fuel Testing – A Stitch in Time

Oil fuel and lube oil testing proves its worth (let the buyer beware) advises chemical analysis specialist companies Lintec and Intertek, telling a few days ago of their joining hands to provide a service to help guard ship operators world-wide against the perils of using off-specification oils. A case study illustrates their point. The entire fleet of a Hamburg-based shipowner was placed on Lintec’s chemical screening programme. On one of the ships, on long-term charter, a sample fuel analysis revealed that bunker fuel containing DCPD (Dicyclopentadiene) and Styrene had been taken on board; the charterer being duly informed of the inherent risks to the ship’s engine that might arise from this bunker stem. Soon, operational difficulties, including blocked oil filters, were reported to the extent that the fuel had to be pumped out and replaced at the next port of call. Further lab analysis was done to determine the exact levels of contamination, with results that persuaded ... [More]

Engine Room Fire Safety – Treat QCV with Respect

Most fires on board ships start in the engine room. One of the built-in safety features increasingly found compromised by U.S. Coastguard Port State Control Officers are malfunctioning fuel Quick-Closing Valves (QCVs). Some  QCV’s are espied deliberately blocked by a variety of means according to Marine Safety Alert 01-11 putting the vessel and its crew at greater risk in a fire emergency. QRV Wedged Open: Photo credit US Coastguard Perhaps an overzealous application of the recommendation by the USCG that routine checks of QCV systems be carried out led to the following incident reported in the October 2011 edition of MARS (the Nautical Institute’s voluntary and confidential ‘Mariners’ Alerting and Reporting Scheme’) which again focussed attention on the operation of QCV’s. Blackout, Propulsion & Steering Shutdown Follows QCV Test at SeaA loaded small-sized gas tanker nearing the end of a coastal voyage had on board a company superi...

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...

Mass flow meters represent an essential element of further professionalising the fuel supply industry and continuing to build trust with ship owners and operators, says OW Bunker, one of the world’s leading suppliers and traders of marine fuel oil. [More]
