Claim 0:
1. A method of installing a subsea system comprising the steps of:
installing at least one first foundation structure on a seabed, wherein the first foundation structure comprises a connection interface configured to connect to a second foundation structure which is configured to at least partly support an additional compressor train on the seabed, and wherein the additional compressor train increases the subsea system capacity;
installing a first compressor train on the first foundation structure, the first compressor train comprising at least a first compressor;
connecting the first compressor train to at least one well flow line, the first compressor train comprising a fluid line connected to an inlet of the first compressor;
connecting a first compressed fluid line to an outlet of the first compressor and to a common outlet for the compressed fluid in the subsea system, wherein the first compressed fluid line comprises a flow regulation device;
connecting a first connection line to the first compressed fluid line at a position upstream of the flow regulating device and/or connecting a third connection line to the fluid line at a position upstream of the first compressor, wherein each of the first and third connection lines is configured to connect to the additional compressor train supported at least partly on the second foundation structure, and wherein each of the first and third connection lines comprises a corresponding flow regulation device; and
connecting a second connection line to the first compressed fluid line at a position downstream of the flow regulation device, wherein the second connection line is configured to connect to the additional compressor train positioned at least partly on the second foundation structure, the additional compressor train thereby being connectable to the common outlet, and wherein the second connection line comprises a flow regulation device.
