Embodiment Construction

[0015] Such as figure 1 and figure 2 As shown, the illustrated embodiment of a platform building 1 according to the invention comprises a main platform 2 and mooring means comprising a submerged mooring buoy 3 . In a corresponding manner as in the introductoryly described patent specification, the main platform 2 is designed as a vertical, substantially flat-bottomed cylinder. Platforms may have circular or polygonal cross-sections.

[0016] Unlike previously known platforms, the cylinder in this case is provided with a vertical shaft 8 in the center, the lower end of which is adapted to receive and releasably lock the mooring buoy 3 . The platform has two walls and possibly two bottoms used as ballast tanks 4 . They are divided into a sufficient number of bins to ensure handling of damage stability etc. A packing storage tank 5 is provided inside the ballast tank for storing hydrocarbons. Below the living quarters 18 on the main deck 7 there will be an engine room and v...

Abstract

A floating platform for drilling after or production of hydrocarbons comprises a semi-submersible main platform (2) carrying process and / or drilling equipment at its upper surface (7), and which is designed as a vertical, essentially flatbottomed cylinder. The main platform (2) is provided with a central vertical shaft (8) which at its lower end is adapted for reception and releasable locking of an anchoring buoy (3) carrying fastening equipment for anchoring lines (10) and for risers (14, 15) and umbilicals.

Description

technical field [0001] The present invention relates to a floating platform for producing hydrocarbons after drilling or offshore, comprising: a semi-submersible main platform with processing equipment and / or drilling equipment on its upper surface, and the semi-submersible main platform The main platform is designed as a vertical, substantially flat-bottomed cylinder. Background technique [0002] A platform designed as above is known from Norwegian Patent No. 319971. By designing the platform with a cylindrical platform body, the pitching and rolling motions are substantially reduced. In addition, such platforms have a large load capacity relative to production or drilling equipment, and have a large storage capacity for oil, fuel, and the like. The platform is directional independent with respect to the surrounding environment and thus can be moored by means of a simple fixed mooring system. In addition, the lifter can be connected directly to the receiving system on t...
