  • Patent number: 7108070
    Abstract: A GTL facility for a fixed offshore hydrocarbon production platform which comprises a deck attached to a base that is secured to the sea floor. The GTL facility comprises a syngas reactor for converting natural gas into syngas and a liquids production unit for converting the syngas into a hydrocarbon liquid. Furthermore, at least one of the syngas reactor and the liquids production unit comprises a catalyst which is constructed using PI micro-reactor technology. As a result, the GTL unit is sufficiently small to be located on the deck of the platform.
    Type: Grant

  • Publication number: 20030225169
    Abstract: A method and apparatus for converting natural gas from a remote source into hydrocarbon liquid stable at room temperature, comprising a skid or trailer-mounted portable gas-to-liquids reactor. The reactor includes a preprocessor which desulfurizes and dehydrates the natural gas, a first-stage reactor which transforms the preprocessed natural gas into synthesis gas, and a liquid productions unit using a Fisher-Tropsch or similar polymerization process. The hydrocarbon liquid may be stored in a portable tank for later transportation or further processed on site in a portable hydrocarbon cracking unit to yield fuel or lubricating oils.

  • Patent number: 6059620
    Abstract: An improved arrangement for connection of a disconnectable spider buoy to an internal turret of a floating production storage and off loading vessel is disclosed. Risers from subsea wells are connected by quick disconnect/connection devices to pipes which run through the turret and then via a product swivel to lines leading to storage tanks on the vessel. A structure is provided to create an enclosed space to enclose the connection devices at the top of the spider buoy. A ventilation shaft runs from the enclosed volume to atmosphere via the top of the turret. A forced air line is provided into the enclosed space for ventilating the space via the ventilation shaft during normal operations. If a gas leak is sensed in the enclosed space, the forced air line is closed. The small volume which surrounds the connection devices quickly fills with hydrocarbon gas to produce a high gas/air ratio in the enclosed space which greatly reduces danger of explosion.

  • Patent number: 5755607
    Abstract: An improved mooring system for a vessel (10) having a mooring turret (19) which is rotatably coupled to a well (14) of the vessel (10) such that the vessel (10) is free to weathervane about the mooring turret is disclosed. An anchor leg support base (18) is fixed with the mooring turret (19) with anchor lines (20) secured thereto and anchored to the sea floor (24). A riser turret (25) is rotatably coupled to the mooring turret (19) and is fixed to the well (14) of the vessel. A riser support base (100) is pivotally coupled to a riser support device (30) for mounting the upper ends of a plurality of flexible risers (48) extending from the sea floor. The riser mounting device (30) is arranged and designed to pivot about two axes (34, 40) at right angles to each other relative to the riser support base (100).
