<p>A subsea cooler 10 comprises an inlet 11 and an outlet 13 that can be connected to a subsea flow line, at least one distributing manifold 16 arranged in fluid communication with the inlet, and at least one collecting manifold 20 arranged in fluid communication with the outlet, and at least one cooling pipe 22 extending between the distributing manifold and the collecting manifold. The subsea cooler further comprises at least two cooling sections 30, 32, where each cooling section includes at least one cooling pipe arranged to exchange heat with the surrounding sea water. The subsea cooler is provided with at least one valve device for controlling the flow of fluid through the cooling sections. A control unit may be provided for regulating the valve device. Preferably, the subsea cooler comprises a bypass line so that fluid can bypass the cooling sections. In a second aspect, a subsea compressor system (40, fig.8) comprising a subsea cooler is disclosed. In further aspects, methods for removing wax, hydrates, sand or debris, which have accumulated in the subsea cooler, are disclosed.</p> |
