INSTALACAO PARA A PERFURACAO E EXPLOTACAO DE JAZIDAS PETROLIFERAS MARITIMAS

摘要

An improved facility, for the drilling and production of hydrocarbon deposits located in a deep sea bed, includes a central structural column having a bottom end secured to a submarine base mounted on the sea bed and a top end secured to a subsea buoy. A plurality of peripheral tubular conduits are located around the central structural column and connected thereto by a guide device which permits the peripheral tubular amendments to move relative thereto and positions the peripheral tubular conduits in parallel with the central structural column.
