But after 24 hours use, the ship’s purifier and fuel system were blocked, requiring engineers to carry out repetitive cleaning of purifiers and sludge discharge piping every 24 hours. Ship and barge samples were taken and analysed, with the fuel recording a total sediment reading of point 7.075 – well within the ISO parameters. He said there are numerous cases in which very low sulphur fuel delivered onboard contains undesirable substances, resulting in problems relating to fuel stability, storage, handling treatment and processing onboard.Ĭiting one example, Sacha Cornell recalled a vessel receiving a batch of very low sulphur fuel in Rotterdam.

He told the 100+ participants that logged on to attend Bunkering Challenges 2021: “I would guesstimate that the extra cost for additional sampling, onboard test kits, increased purifier maintenance, supply and installation of cermet piston rings, treatment chemicals, additional filtration equipment is in the region of between US$10,000 and $20,000 per ship per annum.” Image Credits: Sacha Cornell, Fleet Manager, Norbulk Shipping Speaking recently during a webinar organised by trade association management company Maritime AMC, Sacha Cornell, Fleet Manager, Norbulk Shipping, revealed that using low sulphur fuel can add as much as US$20,000 to the operational expenditure for each ship per annum.

The introduction of rules last year to reduce ship sulphur emissions is resulting in a significant hike in operational expenditure for ship managers, with the use of low and very low sulphur fuel potentially resulting in system and engine damage.
