VPS warns against ISO 2016 marine fuel changes

Shipowners could end up with contaminated and off-spec fuel oil if the proposed International Organization for Standardization (ISO) 2016 rules are approved, an executive at fuel testing company VPS claimed.

If approved, the new rules would remove two clauses from the ISO 2012 standard and "suppliers will lose important protections against chemical contaminants be blended into fuel oil; and they could also be forced to accept fuel that has tested off spec and/or outside of legal limits without recourse to the supplier", he told Argus.

The two ISO 2012 clauses proposed to be dropped from the 2016 update state "fuels shall be free from any material that renders the fuel unacceptable for use in marine applications" and that "the fuel shall not contain any additive at the concentration used in the fuel, or any added substance or chemical waste…" McNamara suggested that if the ISO 2016 standard goes into effect, shipowners should continue to specify 2012 standards or include additional clauses in their bunker contracts.

VPS data shows that globally, most of the fuels they tested were compliant with the ISO's older 2005 standard. About 60pc of their tested samples were ISO 2005 compliant, 25pc were ISO 2010 compliant and 15pc were ISO 2012 compliant.

According to VPS' marine fuel testing statistics, the specifications for which heavy bunker fuels most often exceed limits are viscosity and density. Marine gasoil (MGO) has the most off-specifications for pour point, appearance, flash point and FAME. McNamara noted that some bunker buyers "have the misconception that MGO is a homogeneous product with consistently high quality," and for that reason MGO is not tested as frequently as heavy bunker fuel. VPS data shows that there are frequent issues with MGO quality.

A January 2015 regulation required vessels to switch from burning 1pc sulphur bunkers to 0.1pc sulphur bunker in the designated European and North American Emission Control Areas. To meet the regulation, shipowners moved from burning 1pc sulphur residual fuel oil to 0.1pc sulphur MGO. As a result, VPS saw an increase in the quantity of MGO tested.

There is little buying interest for ECA-compliant fuels in the US currently, McNamara told Argus. "We have seen customers buying in New Orleans and New York, but not consistently. We see most of the activity in the ARA ports and Russia," he said.

Argus began assessing prices for ECA-compliant fuels in the ports of St Petersburg and Ust Luga, on Russia's Baltic Sea, in July 2015 and in Rotterdam, the Netherlands in February 2016. ECA-compliant bunkers in St Petersburg are typically the cheapest of the three. In October, Argus priced St Petersburg at a $69/t discount to Rotterdam and at a $5/t discount to Ust Luga.
