According to SRC general manager, Tony Anderson, "The unplanned stoppages [will] affect a 90,000 bpd CDU and a 12,000 bpd reformer. We plan to do furnace work on both units."

"We may end up taking a little less crude, but it won't be a big change," he added. Anderson did not elaborate on the reason behind the unscheduled stoppage but said that the reformer was running at 100 percent capacity.

SRC is one of three refiners in Singapore. Its Jurong Island refinery has three CDUs with a total nameplate capacity of 285,000 bpd and Anderson confirmed that the refinery was operating at about 250,000 bpd.

SRC is jointly owned by Singapore Petroleum Co (40%), ChevronTexaco Corp (30%) and BP Plc (30%).
