UPDATE 1-Marine fuel floating storage builds in Asia ahead of new shipping rules

(Updates with data from analysts at Refinitiv)

SINGAPORE, Oct 25 (Reuters) - Stockpiles of low-sulphur marine fuels held in floating storage around the Singapore trading and pricing hub are steadily growing ahead of a 2020 global deadline for rules that have shaken the global oil refining and shipping industries.

A total of 32 ships, mostly supertankers capable of carrying 300,000 tonnes or more of oil, are currently anchored in Malaysian waters near Singapore accumulating stores of IMO-compliant fuels on board, according to data released by intelligence firm Kpler on Thursday.

Kpler estimates total fuel oil floating storage at 5.765 million tonnes and a total 4.455 million tonnes of compliant fuel oil in floating storage.

Other researchers say the total may be even higher.

Analysts at Refinitiv in Singapore said on Friday there were about 7.3-7.5 million tonnes of LSFO (low-sulphur fuel oil ) and related blendstocks in floating storage around the Singapore hub onboard 29 supertankers.

This is higher than the 7 million tonnes of LSFO volumes in floating storage Refinitiv analysts tracked at the beginning of the month.

A mandate by the International Maritime Organization requires ships globally to reduce the sulphur content in their bunker fuel to 0.5% from January from the current 3.5%, shaking up the global bunkering industry that consumes some 4 million barrels per day.

To comply, most ships are widely expected to switch to burning LSFO or to more expensive marine gasoil. Shipowners can also install costly exhaust gas cleaning kits called “scrubbers” that allows them to continue burning cheaper high-sulphur fuels.

To meet the growing demand for LSFO, traders and suppliers are building inventories of the fuel around Singapore which is by far the world’s largest bunkering hub.
