The Deep C® Subsea HP Jetting system is deployed to the seafloor and is powered from the surface via an umbilical. Utilization is maximized as the pump is placed at the sea bottom, avoiding significant energy loss by avoiding topside jetting supply. The set up requires minimum deck space and installation time. Futhermore, the system supports higher safety for personell on deck as no equipment is pressurized on deck. The system can be operated as stand alone or integrated in Deep C® SUV or Deep C® Subsea Dredge.
