Cases of off-spec bunker fuels decreased at Singapore port between the period of 1st to 14th July 2018, according to fuel quality data provided by Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS).
There were zero cases of off-specs regarding cat fines recorded during the period, compared to a single case noted within the earlier fortnight.
The report was prepared to fuel tested in accordance to ISO 8217 6th edition.
The U.S. Coast Guard notes standard ISO 8217 tests will not able to detect issues specifically concerning phenolic compounds found in marine fuel.
The top three off-spec bunker ports for the period between 1st to 14th July 2018 are as follows:
