COPC Response Team and Technology

COPC brought in experts from around the globe to assist in the safe implementation of its response efforts, which included deploying specialized, advanced equipment and technology. Experts and equipment included:

• Leading, experienced COP operations and technical experts were brought into China from our global operations to assist with the containment and remediation efforts.
• Utilized state of the art monitoring technology, such as a multi-sensor leak detection system, a underwater color video system and a dual frequency identification sonar acoustical cameras, to detect and monitor subsea leaks.
• Sediment Profile Imaging to photograph sediment below the seabed for analysis of potential subsurface hydrocarbon residue.
• Applied Science Associates (ASA), a world leader in environmental impact assessment modeling, was hired to forecast the ultimate fate of the crude oil released during the B- and C-events, as well as the potential environmental harm caused by the incidents based on the spill volume estimates.
• Newfields, along with a local laboratory, performed chemical analysis and oil fingerprinting of the samples.
• CSA (Continental Shelf Associates), a leading marine biologist and expert in marine impact assessment that also conducted a marine sampling program in the Gulf of Mexico for the Macondo oil spill.

Seep Containment Technology

Seep Containment Device: Since the seep containment and oil collection system was installed in July, 2011 it has proven effective in containing residual hydrocarbon emissions from the identified seepage point close to Platform B.　 Analysis from the fluids pumped from the seepage containment device demonstrates that the seep near Platform B has been effectively controlled.　

Since it was first installed, the system has been modified to better ensure the safety of those working with it and to make sure no further hydrocarbons are released. To this extent, the original containment device has been replaced with a larger one, and the 12" hose has been replaced with a 2" high-pressure armored hose. 

How does it work? The subsea seep containment system contains and collects the seepage at the seabed source. The oil then rises up or is pumped into the collection chamber through the subsea fluid riser hose since oil is lighter than water. During the collection process, gas is separated within the seep tent and vented through the vent pipe. The oil in the collection chamber is then pumped out through an inlet located close to the surface through a hose. The oil is collected in the storage vessel on a boat.
