Collecting and managing heavy fuel oil after the sinking of the Grande America

march 12, 2019. The container ship Grande America sinks off La Rochelle. 6 marine pollution response vessels are deployed to recover the fuel spilled at sea. At the port, Séché Urgence Intervention (SUI) mobilizes to transfer, store and transport the heavy fuel oil to hazardous waste treatment centers.

Ravaged for two days by a fire on board, the ro-ro container ship Grande America finally sank hard on March 12, 2019, in the Bay of Biscay. Some of its propulsion fuel escaped, forming a large slick of hydrocarbons on the surface. To prevent an oil spill, 6 decontamination vessels go into action. And the question soon arose: what to do with the 300 m3 of heavy fuel oil recovered, as well as the various materials soiled during the operations ?

General mobilization

Contacted by the armateur du Grande America, teams from SUI, supported by the Séché group, mobilized at the port of La Rochelle. The aim is to pump the fuel oil from the holds of the decontamination vessels, store it temporarily in the port and organize the transport of all this hazardous waste to the appropriate treatment centers. For the 25 SUI employees the intervention will last nearly 10 days.
