Britain's worst oil spill for over a decade, at the Gannet Alpha oil platform, in the the North Sea, detected and analyzed by e-GEOS Emergency team

On 14th August 2011 a leak in a flow line leading to the Gannet Alpha oil platform 180 km off Aberdeen was found by Marine Scotland. The e-GEOS emergency team was quicklytriggered in self-activation mode.

It has been estimated that 216 tonnes of oil, equivalent to 1,300 barrels, leaked into the North Sea in a "significant spill"

e-GEOS started acquiring daily COSMO-SkyMed images (Wide Region at first, than daily acquisitions with both Stripmap and HugeRegion modes) over the area.

Oil Spill Reports were produced and samples distributed to the main organizations managing this kind of event.

In the framework of the Gannet Alpha Oil Spill activation,the e-GEOS Rapid Mapping team produced, within 7 days from the event:

  • 1 orthorectified COSMO-SkyMed WideRegion image
  • 5 orthorectified COSMO-SkyMed HImage images
  • 3 orthorectified COSMO-SkyMed HugeRegion images
  • 9 OilSpill Detection Report in NRT mode
  • 9 vector layer (SHP), oil spill detection extent
  • 1 KMZ file, oil spill detection extent and quicklook.
