Polluted water still being monitored
The area of the sinking site of the "Grande America" in the Bay of Biscay as well as the water that had been polluted was still being monitored three months after the accident. On June 14 he Maritime Commissioner of the Atlantic, Vice-Admiral Jean-Louis Lozier, pointed out that no new pollution had been reported. One of the masses which was monitored by satellite had recently arrived near the Spanish coast, but no pollution had been reported. The Spanish counterparts were warned, but they found nothing, while the possibility that oil pellets could one day soil the coast could not be finally ruled out. No polluted water has approached the coast of France for the moment, but with the time this probability will reducing. The chance of pellets to arrive was estimated to be extremely limited.
ROV stopped leakages
In response to the Atlantic Maritime Prefect's letter of March 13, 2019, the Grimaldi Group chartered the Norwegian specialized vessel "Island Pride" equipped with a ROV (submarine robot) to inspect the wreck, define its condition and the nature of the damage suffered and to remedy the pollution. The underwater investigations carried out by the ROV, in the presence of an observer mandated by the maritime prefecture of the Atlantic, made it possible to establish that the wreck of the ship was upright, set straight on a sandy bottom, buried several meters on its rear part. Several slight leakages of oil escaped through the vents on some of the ship's seawater ballast tanks and from its fuel tanks. These hydrocarbon leaks explained the presence of low-intensity iridescence on the surface above the wreck. In order to stop these leakages, the "Island Pride" proceeded for several days until April 16 to shut off the vents concerned with the ROV. The "Island Pride" then checked the tightness of the work done on the wreck and completed the survey before leaving the area on April 19. Air assets will continue to regularly monitor the area as well as the EMSA (European Maritime Safety Agency) Cleanseanet satellite system in order to ensure the absence of oil spills. The state services will remain mobilized and attentive to any new developments regarding the situation of the ship.

Observation is continued
The underwater investigations of the "Grande America", , carried out by the Italian shipowner Grimaldi, were continuing off La Rochelle. The Norwegian offshore ship "Island Pride", equipped with ROV, returned to the location from Brest on April 9, to further examines the wreck in a depth of over 4,000 meters. The wreck was found resting upright on a sandy bottom and was buried several meters with its rear part. Aerial observations by a Falcon 50 of the French Navy and a Beechcraft 350 of the French Customs showeed some low intensity iridescence on the water surface above the wreck. These residues of oil and oil disappeared under the effect of the natural mixing of the sea and were not recoverable by the BSAA vessel "Argonaute" which was sent back to the port of Brest by the end of last week. Air assets continued to monitor the area, as well as the EMSA satellite system Cleanseanet, the European Maritime Safety Agency, to ensure that there were no significant oil spills from the wreck.Upload News
