NEW ORLEANS — Remote operated vehicles deployed from the offshore construction 
vessel Skandi Neptune collected oil samples on Wednesday from the underwater 
site of the Deepwater Horizon incident to determine the source of a surface 
sheen discovered last month. 
The samples were taken after the ROV video showed apparent oil globules leaking 
from the containment dome at approximately 15 globules per minute, which is 
estimated to be less than 100 gallons per day. In 2010, the 40‐foot‐tall 
containment dome was used as part of an attempt to capture oil and allow it to 
flow through a pipe to a barge on the surface. This technique was not 
successful and the equipment was moved away from the well head and riser pipe, 
and set in its current position approximately 500 meters from the original 
Macondo well head. It is entirely separate from the well head and any riser 
piping. Out of an abundance of caution, the ROV also inspected the original 
Macondo well area including the wreckage, debris, relief wells, and the riser 
on the sea floor and observed no oil leakage from that area. 
The two collected oil samples will be used for lab analysis. One sample will be 
shared by BP and Transocean, and the second sample will be used by the Coast 
Guard. The lab analysis will help determine if the containment dome is the 
likely source of the recent sheening. 
“The Coast Guard is further evaluating what is believed to be seepage from the 
containment dome to determine how best to respond,” said Capt. Duke Walker, 
Federal On‐Scene Coordinator for the Deepwater Horizon response. 
The ROV operations were observed by the Coast Guard, Bureau of Ocean Energy 
Management, Bureau of Safety and Environmental Enforcement, the Department of 
Interior’s Trustee, BP, Transocean and state on‐scene coordinators from 
Louisiana, Mississippi and Florida. 
The Skandi Neptune departed for the vicinity of the Deepwater Horizon incident 
Sunday to identify the origin of an oil sheen first reported to the National 
Response Center Sept. 16. The Coast Guard issued a Notice of Federal Interest 
to BP and Transocean after the reported sheen was correlated to the oil that 
originated from BP’s Macondo well.

The public is reminded to contact the National Response Center at 
1‐800‐424‐8802 to report all pollution incidents or the Coast Guard 8th 
District command center at 504‐589‐ 6225 in the event of any marine emergencies.
