V.Group Limited (V.Group) says a study carried out by its SeaTec Condition Monitoring team involving 3,000 bunker samples has shown the most common causes for off spec bunkers.

For HFO, water content was found to be the top reason for off-spec bunkers, followed by kinematic viscosity at 50 degrees centigrade, and cat fines (Al + Si).

For distillates, carbon residue was said to be the most common cause for off-spec fuel, closely followed by pour point in winter, and the acid number.

Belgium, Germany, and Gibraltar are noted by V.Group to be the top three countries in terms of percentage of normal samples tested during the study.

The company says testing was carried out to ISO 8217 in a UKAS 17025 laboratory, but did not specify which revision of the standard was used.

The analysis is available on both the company app and online platform.

In February, Veritas Petroleum Services (VPS) and INTERTANKO voiced concerns over proposed revisions to the ISO 8217 specifications for marine fuels, arguing that they may undercut the efforts of the shipping industry toward improving fuel quality.
