Two weeks after the incident on board a ship in charge of drilling for the wind farm in the bay of Saint-Brieuc, new marine pollution was detected on Wednesday in the Ouessant rail (Finistère).
According to the first observations carried out by a Falcon 50 maritime surveillance aircraft of the French Navy, "the fragmented pollution extends over several square kilometers", indicates the Maritime Prefecture of the Atlantic in a press release.
The liquid spilled into the sea would be composed of light fuel and "spreads out in a thin surface layer", specifies the prefecture.
Investigations were immediately launched to find the polluting ship, but they look very complex.
"The already dispersed form of pollution indicates that the discharge is not recent", underlines the prefecture, specifying moreover that the significant maritime traffic in the zone "makes the identification of the polluting vessel more complex, which therefore quickly appears difficult or even impossible ".
The tablecloth could disperse naturally
As soon as the pollution alert was triggered, significant resources were dispatched to the area to follow in real time the evolution of the water table which "is stabilized at 60 km from the coast, does not drift much and therefore does not present any danger in the short term. for the Finistère coast ”. Early this Thursday morning, the ship
Le Sapeur
de la Marine also analyzed the residual pollution "and observed the rapid dilution of the pollutant", adds the maritime prefecture.
He is always in the area to bring back in his trawl the last pollutants which are "in relatively small quantity and not very thick".
"Their nature makes possible a dispersion by natural and mechanical mixing over the coming hours," said the prefecture, which will still maintain an aerial surveillance system in the next 24 hours.
