| 20120103621 | SUBSEA SYSTEM WITH SUBSEA COOLER AND METHOD FOR CLEANING THE SUBSEA COOLER - 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. | 05-03-2012 |
| 20120097362 | SUBSEA COOLER AND METHOD FOR CLEANING THE SUBSEA COOLER - 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. There is also disclosed a method for removal of accumulated wax, hydrates and sand and debris which has accumulated in the subsea cooler wherein separate cooling section are shut off whereby the temperature of the fluid flowing through the subsea cooler is increased thereby melting the wax and hydrates, and whereby the speed of the fluid flow through the subsea cooler is increased thereby jetting out sand and debris. | 04-26-2012 |
