FOBAS: Surge in bunker off-spec cases at Antwerp port during 2H May

06 Jun 2019

Fifty eight off-spec marine fuel cases were identified by the Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) during the period between 15 to 31 (2H) May 2019.

The off-spec cases occurred when a result was outside the 95% confidence limit of either ISO 8217 6th edition test parameter or a value given by the BDN or sample label.

There was an increase in off specification marine fuel cases concerning viscosity at the Belgium port of Antwerp; the development replaces Singapore, which traditionally experiences the most number of off-spec cases due to its volume, as the top off-spec bunker port in the period of 2H May.

The top bunker ports with reported off-spec bunker fuel cases in 2H May are as follows:

Port  Characteristic  ISO 8217

Final result Unit
Antwerp Viscosity at 40°C 4.00** 6.06 cSt

Balboa Water 0.50* 0.95 % Volume

*ISO 8217 6th edition limit
**Advised value from BDN or sample label
***Due to the statutory significance of Flash Point the 95% confidence limit is not applied
