ABSTRACT:
PCT No. PCT/FR78/00005 Sec. 371 Date Feb. 28, 1979 Sec. 102(e) Date Feb. 26, 1979 PCT Filed June 28, 1978 PCT Pub. No. WO79/00016 PCT Pub. Date Jan. 11, 1979
The invention relates to a method for positioning a support structure for installations outside a petroleum platform and to said support structure.
The structure comprises a biped tower (2) supporting a bridge (1) which supports a flare (3) at one of its ends. The structure, in folded towing position, floating by means of floats (26) and dead men (10), is towed to the site, the tail of the structure is supported by the platform (40), and the dead men (10) and then the floats (26) are ballasted when the tower (2) is in vertical position. When the feet of the tower rest on the ocean bed (11) the tail is hoisted onto the platform (40) in order to anchor it to the latter and the floats (26) are recovered.
The invention is applied to a flare support for a marine platform.
