SUBSEA COOLER

摘要

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).

1: A subsea cooler comprising:
at least one pipe for a fluid to be cooled, the pipe comprising a pipe inlet and a pipe outlet and being formed of a number of straight sections connected by bend sections; a housing which encloses at least a part of the pipe and which comprises an inner surface that together with an outer surface of the pipe forms a flow channel extending along and surrounding the pipe; the flow channel being fluidly connected to an inlet and an outlet for a cooling fluid and to a pumping element for driving the cooling fluid through the flow channel; at least one sacrificial anode which is positioned in the flow channel in electrical contact with the pipe; wherein the flow channel comprises at least one cavity which is configured to receive corrosion products from the sacrificial anode.
