FOST is a stockpile of oil pollution response equipment, 100% belonged to the TotalEnergies group.
It was created by Elf Aquitaine in 1993 following the explosion of the tanker MEGABORG and is now fully owned by Total following the merger of the groups Total FINA and ELF in 1999.
The historical vocation of the FOST was to intervene in France, in the Mediterranean basin, and in West Africa.
In 2002, FOST moved from Marseille-Provence to Rognac to increase its storage space. At the end of 2020, FOST is located in Vitrolles, in the Anjoly Industrial Area, a few kilometers from the Marseille-Provence airport.
