摘要

Invention patent: "system with a structure of a guide for ascension pipes of oil production; structure of guide for ascension pipes; elements of fluctuation of ascension pipes and a platThe form of production semi submersu00ecvel ".The invention relates to a system for use in the production of oil at sea, with a structure of guide (2) for one or more ascension pipes (3), in a production semi submersible vessel (1),With one or more elements of the main float (4) arranged separately on at least one ascending tube (3), to drive the main part of the weight of the ascension pipes (3).Each ascending tube (3) is willing to lead, separately, a Christmas tree (6) at the top, next to the deck (10) of the vessel (1).The structure of the guide (2) comprises vertical main elements (7) arranged to extend vertically descendentemente deck (10).The area of splash and the area more strongly influenced by waves and current above the sea.The structure of the guide (2) has a horizontal guide plates (20), which comprise cells vertically open a frame disposed horizontally (21) of beams (21 '),With lateral stabilization devices (24) for guiding the relative movement vertical upward tubes (3) and of the elements of the main float (4) and to restrict the relative movement horizonAs regards the structure of the guide (2).The guide plates (20) are arranged in at least two levels in the structure of the guide (2),A lower guide plate (20) arranged in level with the lower extremities of the main elements of vertical (7),And a plate guide (20) prepared at a level below or near the splash zone.At least one element of the main float (4) is willing to be maintained in the ascending tube (3) in level with,And guided by lateral stabilization devices (24) arranged in one or more plates of guide (20).Below the area more strongly influenced by waves and current higher next to the sea surface.And with the ascension pipes (3) being essentially without the elements of the fluctuation by the splash zone, so that they are less exposed to the forces of water in the upper area of the sea.
