Abstract

A system for subsea pumping or compressing includes an ESP (electrical submersible pump), a flowline jumper, a connector part in either end of the flowline jumper, and a truss structure or longitudinal rib-arrangement that acts as a stiffening arrangement. The ESP may be arranged in the flowline jumper which may be orientated in a substantially horizontal direction. The stiffening arrangement may function to ensure that the ESP shaft is straight at all times during lifting, installation and operation. The system may also include a load limiting arrangement for limiting or eliminating the load on structure and seabed supporting the system.
