One year on, indications are that the transition has been extremely smooth, a testament to the preparations of all stakeholders prior to the new rules entering into force.
The upper limit of the sulphur content of ships’ fuel oil was reduced to 0.5% (from 3.5% previously) – under the so-called “IMO 2020” regulation prescribed in the MARPOL Convention. This significantly reduces the amount of sulphur oxide emanating from ships.
The majority of ships trading worldwide switched from using heavy fuel oil (HFO) to using VLSFO. Generally speaking, these are new blends of fuel oil, produced by refineries to meet the new limit, in accordance with IMO guidance and ISO standards.
Guidance issued by IMO on dealing with the new fuel blends in advance of the new requirement addressed implications of switching to VLSFO, including assessing and managing risks and highlighting potential safety risks, so that the risks can be mitigated.
Through 2020, and into 2021 to date, IMO has not received any reports of safety issues linked to VLSFO.
Nonetheless, during 2020, an IMO correspondence group considered fuel oil safety issues in general and the need for further mandatory requirements to ensure fuel oil supplied meets the required standards and quality. The report of the group (MSC 102/6) is available on IMODOCS and will be discussed at the next session of IMO’s Maritime Safety Committee (MSC), MSC 103 in May 2021.
