The IMO''s global sulphur fuel cap has not eradicated the potential threats from cat fines, sludge, compatibility issues, asphaltene and fuel stability that can damage the health and maintenance of diesel engines.

This is according to Aderco, which develops, manufactures and distributes specialised fuel additives. The company said reducing the sulphur content in compliant fuels and, more especially, Ultra Low Sulphur Marine Gas Oil (ULSMGO), results in a marked increase in microbial growth.
The use of biodiesel in the blending process can generate a high water content which is the ideal breeding ground for bacteria. This poses a real risk to the engine’s pipework and filters which could result in catastrophic failure. However, using a fuel treatment eradicates any biological damage.
Olivier Baiwir, CEO of Aderco, said: “The new low sulphur fuel hasn’t stopped the issues of fuel instability and contamination which are of primary concern for ship owners, ship managers and operators."
The company's new report follows a series of tests conducted in Belgium and Singapore on low sulphur fuels over recent months. The tests show the marked improvements that can be achieved from a fuel treatment in reducing commingling and improving fuel stability, reducing sludge and removing water from the new fuels.
Mr Baiwir stressed that a reliable fuel treatment can ensure the operation of diesel engines without the worry about costly engine failures, lay-up or any off-hire.
