"Appliances to support the ascension pipes of the hull of vergu00c8ntea,And to suspend and pulling a tube upward of a superfu00eccie associated to the hull of vergu00c8ntea and to allow limited movement between the rotating tube upward and the superfu00eccie, and.Method for supporting a tube upwards in a hull floating vergu00c8ntea ".A floating platform type vergu00f3ntea (10) having tubes (16) moving vertically upward by the central well (24) of a vergu00f3ntea hull (12).Apparatus is provided to support the ascension pipes (16) a table with a cardan suspension (28) supported above the top of the hull of vergu00f3ntea (12).The table is supported flexibly by a plurality of springs nonlinear (32) connected to the top of the hull of vergu00f3ntea (12).The non-linear springs (32) are conformadamente table (28) alternately.So that the table (28) is allowed a limited degree of rotational movement with respect to the hull of vergu00f3ntea in response to environmental loads induced by wind and current.Non linear springs of greater capacity (32) are located near the center of the table to support most of the traction of the ascending tube.And nonlinear springs lower capacity are located close to the perimeter of the table for controlling the rotational stiffness of the table (28).The table support ascending tube comprises a grid of interconnected beams (38) having openings (40) between them, through which pass the ascension pipes.The nonlinear springs may be in the form of block load elastic or hydraulic cylinders, or a combination of both.The upper ends of the tubes are supported from the table by upward hydraulic cylinder upward tube (44) that can be atuados individually to adjust the traction in lengthThe ascension pipes.Units of flexing elastomeric (48) devices or articulation of the knee (54, 56) are arranged between the hydraulic cylinders of traction ascending tube (44) and the table.In order to allow rotational movement between each tube upward and the table.
