摘要

"The ascending tube system for use in a floating platform of quiet deep, deep draught and floating platform for drilling and / or production of oil from the sea bed".A floating platform off the coast for drilling and / or production of petroleum products from the sea bed includes a deck of production and a buoyancy apparatus vertically GuideThe and retained within the platform. The apparatus includes a deck buoyancy wellhead in its upper surface on which are mounted at least two trees of the surface.At least two upward vertical tubes are supported by buoyancy and apparatus are connected to the deck of the well.Each of the ascension pipes is connected to one of the trees of the surface extends down through the buoyancy apparatus for connection to a head shaft of the sea bed.At least one set of tendon is the device of buoyancy to the seabed.The set of tendon is constructed with at least two concentric tubular elements of tendon and he is strapped to the deck of the well and extends along the center line of the vertical device of floatAbility.A collector on the deck of shaft is smoothly attached to trees of the surface through a choke pressure reduction and a bridge of low pressure smoothly engages the collector to a deviceTreatment of oil on the deck of the production.
