Abstract: A system for recirculating a portion of a liquid fraction of multiphase production fluid to a pump for enhanced functionality thereof. The system includes a splitter assembly that obtains the multiphase production fluid from the pump. The splitter assembly utilizes multiple internal chambers to separate gas and liquid fractions of the fluid. A portion of the liquid fraction may then be recirculated back to the pump as indicated whereas the remainder of the liquid fraction may be recombined with the gas fraction for production.

Abstract: A fluid system includes a pumping flowline, wherein the pumping flowline is in selectable fluid communication with a production flowline, a cylinder including a first port and a second port, a piston slidably disposed in the cylinder, the piston sealing against an inner surface of the cylinder to form a first chamber and a second chamber, wherein the first chamber is in fluid communication with the first port and the second chamber is in fluid communication with the second port, and a first flowline in fluid communication with the first port of the cylinder and the pumping flowline, the first flowline including a first flowline valve, wherein, in response to opening the first flowline valve, the piston is displaced through the cylinder in a first direction to expand a volume of the first chamber of the cylinder.

Abstract: The invention concerns a subsea system transporting fluid, wherein the subsea system comprises a first part having a flow path carrying a flow of fluid and at least a second part having a flow path provided for carrying fluid. The second part is temporarily being closed off from the flow path of the first part of the subsea system. The heat from the fluid transported in the first part of the subsea system is transferred to the second part by a heat conducting structure establishing a contact between the first and second part of the subsea system, to prevent the formation of hydrates in the second part of the subsea system.

Abstract: There is disclosed a subsea cooler for the cooling of a fluid flowing in a subsea flow line. The subsea cooler comprises an inlet and an outlet which are connectable to the subsea flow line and at least two cooling sections arranged in fluid communication with the inlet and the outlet of the subsea cooler. Each cooling section includes a plurality of cooling pipes which are configured such that they exchange heat energy with the surrounding sea water when the subsea cooler is in use. The subsea cooler is further provided with valve means such that the flow of fluid through the cooling sections may be regulated individually.

Abstract: There is provided a subsea system for increasing pressure and/or flow rate in a flow line, the subsea system being arranged in fluid communication with said flow line which receives fluid from at least one fluid source. The subsea system comprises at least one compressor or pump and at least one subsea cooler which is arranged in the flow line in series with the at least one compressor. The subsea system further comprises a recirculation line which is configured such that at least a portion of the fluid flowing in the flow line downstream the at least one compressor and the at least one subsea cooler may be recirculated back to the flow line upstream the at least one compressor and the at least one subsea cooler such that the recirculating line can be used for capacity regulation of the at least one compressor and cleaning of the at least one subsea cooler.
