  • Patent number: 10782073
    Abstract: A waste heat boiler system for cooling a process gas, including a first shell-and-tube heat exchanger for cooling relatively hot gas down to relatively warm gas, an intermediate chamber for receiving gas, cooled down to relatively warm gas, coming out of tubes of the first heat exchanger, and a second shell-and-tube heat exchanger for cooling relatively warm gas further down to relatively cool gas. The intermediate chamber is provided with an outlet fluidly connected to a bypass channel for allowing a part of the relatively warm gas to bypass tubes of the second heat exchanger.

  • Patent number: 10711537
    Abstract: A system and a method for an offshore platform that is self-installing, not requiring use of a heavy lift vessel for installation at a site. The system has a built-in, retractable, suspended, conductor guide support frame assembly coupled to the hull of the platform and serves as lateral guide/support for the well conductors/casings during operational conditions. The conductor guide support frame assembly is generally raised during wet tow/transit. At the site, the conductor guide support frame assembly is lowered and secured into the sea to its designated elevation. The conductor guide support frame assembly generally remains suspended from the hull and does not need to extend all the way to the seabed foundation. After operations are completed, the conductor guide support frame assembly is generally raised up relative to the hull, and the whole platform with the conductor guide support frame assembly relocated for reuse at a new site.

  • Patent number: 10655437
    Abstract: The present invention provides a buoyant system and method for a hydrocarbon offshore floating platform to be coupled and decoupled from a subsea buoyant extension with risers slidably coupled thereto. The buoyant system can allow rigid risers to be coupled and decoupled and alternatively move between a first elevation below the offshore floating platform, such as at the buoyant extension, and a higher second elevation at the offshore floating platform independent of a spool piece, arch support, and flexible joint for the risers. The buoyant system can reduce riser stress by reducing bending required for the riser to form a catenary or other curved shape even as a rigid riser.
