Abstract: A cooler system has at least first and second coolers which are arranged in series, at least a third cooler which is arranged in parallel with the first and second coolers, and at least one flow control device for directing a fluid flow through at least one of the coolers. At least one of the coolers includes a bypass circuit or a recirculation loop for the fluid flow.

Abstract: A subsea cooler has at least one pipe (1) and a housing (4). The pipe has an inlet (2) and an outlet (3) for a fluid to be cooled and comprises straight sections (5) connected by bend sections (6). The housing (4) encloses at least a part of the pipe and comprises an inner surface forming a flow channel (8) extending along and surrounding the pipe. The flow channel (8) is fluidly connected to an inlet (9) and an outlet (10) for a cooling fluid and a pumping element for driving the cooling fluid through the flow channel (8). At least one sacrificial anode (11) is positioned in the flow channel (8) such that the sacrificial anode is in electrical contact with the pipe (1).

Abstract: A cooler system having an inlet (A) and an outlet (B), the cooler system comprising; at least a first cooler (20, 21, 22, 23, 24) and a second cooler (20, 21, 22, 23, 24), wherein the first cooler (20, 21, 22, 23, 24) and second cooler (20, 21, 22, 23, 24) are arranged in a series connection, the cooler system further comprises at least a third cooler (20, 21, 22, 23, 24) which is arranged in parallel connection with the first cooler (20, 21, 22, 23, 24) and second cooler (20, 21, 22, 23, 24), and the cooler system comprises at least one flow control device for directing flow through at least one cooler (20, 21, 22, 23, 24) wherein at least one of the coolers (20, 21, 22, 23, 24) comprises a bypass circuit and/or recirculation loop (35).

Abstract: A crude natural gas stream treatment system comprising a first supersonic separator and a second supersonic separator, wherein the first supersonic separator comprises a crude gas inlet, a dry gas outlet and a first liquid outlet; wherein the second supersonic separator comprises a dry gas inlet, a treated gas outlet and a second liquid gas outlet, and wherein the dry gas outlet is in fluid communication with the dry gas inlet is disclosed.

Abstract: The present invention regards a subsea cooling unit having an inlet for a hot fluid and an outlet for cooled fluid, the cooling unit comprising a number of coils exposed to seawater, and means for generating a flow of seawater past the coils, where the means for generating the flow of seawater comprises a propeller and a rotatable actuator and that the cooler is enclosed in a duct.
