ABERDEEN, Scotland, August 15, 2011 (ENS) The oil leak began on Wednesday, on a flow pipeline system that serves the Shell-operated Gannet Alpha platform in the North Sea. But UK authorities say that Shell did not report the leak until Friday and by then more than 200 tonnes of oil had entered the sea.
"It is not easy to quantify the total volume spilled but we estimate so far that it is around 216 tonnes (1,300 barrels)," said Glen Cayley, technical director of Shell's exploration and production activities in Europe.
Speaking from Aberdeen Cayley said, "In terms of the volume on the surface, which changes from day to day, it is estimated today at about one tonne, approximately six barrels."
"This is a significant spill in the context of annual amounts of oil spilled in the North Sea. We care about the environment and we regret that the spill happened. We have taken it very seriously and responded promptly to it," he said.
Personnel on the Gannet Alpha platform are safe and the platform continues to operate.
Today the spill is under control, with the wellhead shut in, said Cayley. "We estimate that the current rate of leaking is less than five barrels a day."
The sheen of oil on the surface is half a square kilometer in size. Shell says the spill is a light crude oil mixed with some hydraulic fluid.
"The high winds and waves over the weekend have led to a substantial reduction in the size of the oil sheen as can be seen from the current levels on the water," Cayley said. "We continue to expect that the oil sheen will disperse naturally due to wave action and that it will not reach the shore."
A spokesman for the UK Department of Energy and Climate Change said, "Shell has informed us that the oil leak at its pipeline at the Gannet Alpha platform east of Aberdeen is under control and has now been greatly reduced. They are working to completely halt any further leakage."
"DECC's environmental inspectors will continue to monitor the situation and have been working closely with the company and counterparts from the Health and Safety Executive, Maritime and Coastguard Agency and Marine Scotland since the spill was reported last week."
The spokesman said, "Although small in comparison to the Macondo, Gulf of Mexico, incident, in the context of the UK Continental Shelf the spill is substantial. But it is not anticipated that oil will reach the shore and indeed it is expected that it will be dispersed naturally."
"Current estimates are that the spill could be several hundred tonnes," he said.
Scottish Environment Secretary Richard Lochhead said, "We take any oil leak extremely seriously, as the first minister has made clear, and we are continuing to monitor this situation very closely."
"While there are inevitable difficulties verifying the extent and size of the leak, it's vital that Shell and DECC make information available on an open, transparent and regular basis," said Lochhead.
"The Scottish Government's primary role is to advise on the impact any spill might have on the marine environment," he said. "Marine Scotland aircraft are currently involved in surveillance work over the affected area. Fishing vessels in the area have also been made aware of the incident."
A standby vessel, "Grampian Prince," remains on station monitoring the area, with oil spill response equipment and dispersant available if required.
Shell's emergency response team remains in place and the company says its personnel are working with the relevant authorities - DECC, MCA, Marine Scotland, and the Scottish Government - to manage the incident and minimize its environmental impact.
