Gannet Oil Platform

On 10 August 2011, a leak was found near the Shell-operated Gannet Alpha platform from a flow line connecting an oil well to the platform. The well was shut, however, oil continued to leak out of the flow line. The relief valve was closed on 19 August 2011 and the seepage of oil was stopped. Up until the closure of the valve an estimated 218 tonnes of Gannet crude oil were released into the surrounding environment. The Gannet Alpha platform is situated in the North Sea some 112 miles off Aberdeen.

A sampling programme was put in place to determine if there was any environmental damage from the oil and Marine Scotland scientists put together a Scottish Marine and Freshwater Science report (Volume 2 Number 12) describing the results of both sensory assessment of the fish and chemical analysis of fish, sediment and water.
