The reconversion of this Jack Up type oil platform is a response to the problem of volatile pollution in the sea water from crops, industry and the ways of life in contemporary society generating waste, but also to the problem of hypoxia leading to the formation of dead zones (without presence of marine life).

The project proposes to implement two scenarios, one for the treatment of plastic waste on the surface and the other for the restoration of the seabed (within the perimeter of the platform formerly in operation). The project takes place before the dismantling of the oil platform and extends its operation over 20 years. The site is located 220km off the coast of Hong Kong and acts as a support base for the floating plastic collection action (boats come to unload their catch of the day on the south side of the platform, then the waste is processed and transformed into granules to be transported back to the territory on the north side). The second scenario allows for a direct action on the local seabed by the removal of waste located on the seabed within the perimeter of the platform in a first step, then the reintroduction of local fauna in a second step with the installation of a 'biohut' allowing fish to nest like on a reef, and the reintroduction of corals. This operation allows to promote and control the reintroduction of life within dead zones.

The Jack Up Reef project is built with the help of a megastructure of large Pratt beam type program as well as the writing of a secondary structure of small program, and finally by the reallocation of the Derrick element. The last issue is to make this nomadic architecture more viable for stays of more than a month by adding a volume reintroducing the perspectives of a territory: the Base Life.
