U.S. oil giant ConocoPhillips found nine new leaks near a platform in Bohai Bay jointly owned by the American company and China’s CNOOC, the State Oceanic Administration (SOA) said.
ConocoPhillips has said more than 2,100 barrels of oil and oil-based mud — a substance used as a lubricant in undersea drilling — have leaked from two platforms, polluting beaches and killing marine life in the area. Further details were not available.
The SOA, which supervises and manages China’s seas, said last week it planned to sue ConocoPhillips over the spill first detected in early June.
A Chinese lawyer is also suing CNOOC and ConocoPhillips over the leaks, state media said last week.
The SOA asked ConocoPhillips to carry out a thorough investigation of the cause of the latest oil leaks to prevent similar cases.
Fishermen in the Shandong, Hebei and Liaoning provinces that border Bohai Bay, east of Beijing, said oil from the leaks killed a large part of their harvest of such seafood as scallops.
Environmental groups have also called on ConocoPhillips for speedier and more transparent clean up efforts.
ConocoPhillips and CNOOC have apologized for the spill, and the U.S. company said last week it hoped to clean up the oil by the end of August.
