The Deep C® Subsea HP Jetting System, is deployed to the seafloor and powered from the surface via an electrical umbilical. Utilization is maximized as the pump is placed at the sea bottom, avoiding significant energy loss by avoiding jetting supply from topside. The set up requires minimum equipment on deck, hence saving significant amount of time for mobilization, and minimizing deck space requirements. Furthermore, higher safety for personnel on deck is achieved, as no equipment (or hoses) are pressurized on deck.
