ABSTRACT:
The field of crude oil exploitation on a sub-marine site. The station comprises a platform 1 of octagonal shape carried by a central column 2 anchored in the ground on which is fixed an effluent collecting module 5. Stacked on the said module is a central control module 60. Fixed in overhanging fashion on six sides of the octagon are frames 10 to 15 adapted to overhang drilling wells and each carrying a production head 30, 40. On the other two sides of the octagon, fixed by means of frames, there are an umblical head 80 and a connecting module 70 for the discharge of effluent.
This arrangement makes it possible to bring a certain number of wells close to the platform and so shorten the distances between the modular units.
