Shell has shut an oil unit at the 237,000 b/d Pulau Bukom refinery in Singapore to investigate a "suspected leak", said the Maritime and Port Authority of Singapore (MPA) and National Environment Agency (NEA) today.
Shell informed the government agencies that they will have to shut one of its "oil processing units" at Pulau Bukom to facilitate investigations into a suspected leak.
The exact oil processing unit cannot be confirmed, but it is a unit "used to produce refined oil products such as diesel". This means it is likely a crude distillation unit or a hydrocracking unit. Shell's initial estimates show that a few tonnes of oil products were leaked, together with cooling water discharge. Sea water is typically drawn to aid in the cooling process, according to the media release.
This came after the 20 October leak at a pipeline at Pulau Bukom, when 30-40t of "slop" — or a mixture of oil and water — leaked into the sea, according to Shell.
The gasoline market has shown little reaction so far with spreads being "stagnant" and "range bound", said a Singapore-based gasoline broker. But this could be because of a lack of market activity, with many traders away for holidays at the end of the year. The gasoil January-February spread last traded at $0.58/bl in backwardation at around 6:30pm Singapore time on 27 December, according to a Singapore-based gasoil broker. This marks a slight increase from an assessment of $0.55/bl in backwardation on 26 December, according to Argus pricing data.
