Abstract: A method and an apparatus for establishing a hydrate free regime in a subsea production flowline before discharging into the subsea production flowline a production flow of hydrate prone hydrocarbon product pursuant to a shutdown or at an initial start of production. The hydrate free regime is achieved by injecting into the flowline a heated water volume in advance of discharging the hydrocarbon product from the subsea production system.

Abstract: A technique is provided for producing a slurry of solid particulates and hydrocarbon production fluid for transport via a subsea flow line. The technique utilizes a cold flow system that cools production fluid to a temperature below the temperature at which hydrates and other substances precipitate from the production fluid and form solid particulates. An instrumentation and control system is used to receive and process data from sensors in the system. The instrumentation and control system then provides control signals to one or more components of the cold flow system to produce a slurry having solid particulates with desirable characteristics. In addition, a cooling gas may be used to facilitate sub-cooling of the production fluid. The cooling gas is compressed and cools the production fluid as the gas expands via Joule-Thompson expansion. Furthermore, a discharge pressure controller may be used to control flow through the cold flow system.

Abstract: The present disclosure is directed to liquid ring compressors that can be employed to remove liquid from a wet gas and/or to compress a wet gas. In one embodiment, a liquid ring compressor includes a shaft, a main body inner casing disposed about the shaft to form a chamber between the shaft and the main body inner casing, and an inlet configured to remove a portion of liquid from a wet gas and to direct the wet gas into the chamber. The liquid ring compressor also includes an impeller rotatably disposed within the chamber and configured to direct a remaining portion of the liquid in the wet gas out towards the main body inner casing to form a liquid ring within the chamber to compress the wet gas.
