After over half a year of low-sulphur gas procedures for worldwide delivery, Chevron Marine Lubricants has actually distilled its experiences of collaborating with brand-new gas and also lubes right into a brand-new whitepaper released.

‘Taking the Temperature of the 2020 fuel sulphur switch’ consists of searchings for based upon deal with ship drivers worldwide to handle the shift from standard high-sulphur gas oil (HSFO) to extremely low-sulphur gas oil (VLSFO)– one of the most extensively made use of methods of adhering to IMO’s 2020 law. The paper additionally discovers what these experiences suggest for delivery as it plans for also better adjustments in the future, as decarbonisation and also various other sustainability targets more impact gas selections.
“Chevron’s observations show that most ship operators managed the transition very well,” states Ian Thurloway, Brand, Marketing and also Business Development Manager forChevron Marine Lubricants “Fuel quality has been less variable than expected and accurate recommendations on cylinder lubrication helped prevent the worst fears from being realised. But there have been engine condition concerns and rigorous monitoring remains a fundamental of any fuel change – particularly faced with a whole new range of clean fuels to choose from.”

Chevron keeps in mind in the whitepaper that VLSFO as a whole has a greater power web content than HSFO, providing excellent worth for individuals. But its quick ignition has actually created issues for some older engines. Meanwhile the method of purging high-sulphur deposits from containers in advance of the law’s entrance right into pressure additionally added to a boost in cyndrical tube problem difficulties early in the year.
The reduced sulphur web content in aquatic gas additionally decreases the safety and security margin in between regular piston running, with a restricted yet workable degree of deterioration, and also destructive unpleasant or glue wear.

To identify these problems prior to they bring about irreparable engine damages Chevron advises that drivers use a durable onboard drip oil surveillance program, sustained by regular onshore research laboratory evaluation. Chevron’s very own DOT.FAST ® solution currently consists of a different indication for abrasive/adhesive wear in its onshore research laboratory evaluations.
“Ship operators can use the DOT.FAST® onboard kit to check if total iron in the drip oil rises,” states Luc Verbeeke, Senior Engineer,Chevron Marine Lubricants “The deeper laboratory analysis then identifies if the drip oil contains greater levels of magnetic iron particles. This would indicate abrasive/adhesive wear, meaning that operators should adjust either the base number or the feed rate of their cylinder lubricant.”
