  • Offshore facility, floating crude oil production facility and method for generating liquefied natural gas
    Patent number: 11738829
    Abstract: An offshore facility for producing a liquefied natural gas using an associated gas includes a crude oil production offshore facility having a crude oil processing device for refining crude oil collected from a subsea well to produce oil, and a gas reinjection device for compressing an associated gas separated in crude oil refining process to be reinjected into a reservoir, and a liquefied natural gas production offshore facility supplied with a feed gas including at least a part of the associated gas from the crude oil production offshore facility, and processing and liquefying the feed gas to generate a liquefied natural gas. The crude oil production offshore facility includes a feed gas supply unit for recovering a back-flow gas formed when an injection gas compressed by the gas reinjection device flows backward and generating the feed gas by using the back-flow gas.

  • Thermal insulation device for at least one underwater pipe compressing sealed partitions
    Patent number: 7069957
    Abstract: The present invention concerns a device for heat-insulating at least one sub-marine pipe. The sub-marine pipe includes a heat insulation covering including a material subject to migration, the covering surrounding the pipe and being covered by a sealed protective envelope having a tubular shape and a longitudinal axis of symmetry. The envelope being constituted by a flexible or semi-rigid material able to remain in contact with the external surface of the insulation covering when the latter warps. The device includes at least two sealed transversal partitions, each being constituted by a closed rigid piece traversed by and integral with the pipe and with the envelope.
