摘要

"Apparatus for communication with a plurality of subsea wells, the method to install an ascending tube communications from a floating platform to a subsea wellhead and ascending tube traction variable to connect a subsea wellhead to a PLA Taforma floating.Are disclosed ascension pipes of variable traction complacent (106) to connect to the deep water subsea well head (102) to a single floating platform (104). The ascension pipes of the traction variable (106) to enable the various underwater well head (102) in the depths of the waters from 4000 to 10000 feet (1.219 up to 3.048 m), in the lateral displacement from one tenth to half the depth, tie a single floating platform semi submersible drilling tower to dry (104). Methods are also disclosed for balance fluctuation and install ascension pipes of variable traction using a line ballast heavy chain (228, 230).
