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. There is also provided a method for the removal of wax and/or hydrate and/or sand and debris which has accumulated in at least one subsea cooler of a subsea system.
