CNOOC Limited announced that an oil sheen was discovered near Jinzhou 9-3 West oilfield in Bohai Bay. According to investigation, the oil spill was caused by the leak from a subsea connecting pipeline damaged by a work vessel during its operations. Initial estimate indicated the amount of leakage was about 0.38 cubic meters.
The following inspection found that there were two oil sheens around Jinzhou 9-3 B Platform, with one 30 meters long by 30 meters wide, the other 80 meters long by 30 meters wide. Until 3:30p.m. on October 15, the company has effectively cleaned up the two oil sheens found on the sea surface.
After the incident occurred, CNOOC Limited immediately activated emergency response procedures, shut down the operations at Platform B of the oilfield and cut off the leaking source. In the meantime, the company took effective measures to clean up the oil sheen as well as sent divers to survey the damaged subsea pipeline and seal the leaking source. Affected by the shutdown, the production is reduced by approximately 1,600 barrels per day.
Jinzhou 9-3 West oilfield is an independent oilfield of the company. CNOOC Limited holds 100% interest and acts as the Operator.
