The following article is part of event coverage for the upcoming Singapore International Bunkering Conference and Exhibition (SIBCON) 2020; where Manifold Times is an official media partner:
International fuel additive company Infineum is still encountering situations where stakeholders of off-spec bunker fuels have been found trying to save their product by using additives in a last minute attempt, according to its Global Fuels Key Accounts Manager.
“Our belief is that fuel suppliers should be providing fuels that not only meet all of the latest required specifications (ISO 8217:2017) but are also fit for purpose for the time that they will be in service and the application for which they are being used,” Steve Benwell told Manifold Times.
“We still see circumstances where a product is ‘off-spec’ and the holder of the fuel is then trying to move it back ‘on-spec’ through the use of appropriate additive technology. In these cases, the ability of additives to ‘save’ the fuel depends on the nature of the problem and its severity.”
According to Benwell, the most common issue seen with Very Low Sulphur Fuel Oils (VLSFOs), a product mainly used by shipowners to meet IMO 2020 compliance, is in sedimentation performance.
“We have also seen many cases where the fuels sedimentation performance is not steady over time, and generally it only ever goes up! VLSFO fuels are typically more paraffinic than the high sulphur counterparts but there is still a desire to get much heavy aromatic material into the fuel since these have high energy density and are cheaper,” he explains.
“This means that many VLSFOs have a higher tendency to destabilise over time as is evident by the higher incidence of sedimentation performance in the industry that is not compliant with ISO 8217.
“This deterioration in sediment performance can occur when fuels are being stored at relatively moderate temperatures (e.g. 50°C) and is not necessarily exposed by the 24-hour aging at 100°C employed in the Total Sediment Potential (TSP) test.
“Addressing this situation through the appropriate additive application can not only protect the fuel holder but also ensure a better experience for their customers further downstream.”
The below list of characteristics and scenarios where the application of additives may, or may not, have an effect on ‘saving’ off-spec VLSFOs has been shared by Benwell:

“The industry is still coming to terms with the new lower sulphur fuels, especially the wide variety of VLSFO options available where even for perfectly fit for purpose fuels, compatibility between some VLSFOs can be an issue and complete segregation on board may be difficult to achieve,” states Benwell.
“Recently, this has been even further complicated by the Covid-19 Pandemic and its impact on the balance that the refining industry has to strike between crude usage and finished products production.
“However, eventually, we expect the industry to address the issues associated with these new fuels through appropriate specification changes and we expect the ship operators to demand the level of fuel quality required for them to operate their ships without fear of equipment damage or operational difficulties.”

Bunker claims totalling SGD 628,000 for 88 deliveries of marine gas oil between the period of 7 February 2020 until 15 April 2020, according to documents obtained by Manifold Times.
Event welcomed over 1,100 attendees from 42 countries; delegates visited virtual booths about 4,800 times; while around 5,800 connections were made, according to data from organiser Informa.
Bunker suppliers and bunker craft operators may choose to carry out meter verification using either existing MIMO method OR with the use of a Master Meter.
