The Deep C Subsea HP Jetting System is a high-performance subsea pumping unit that delivers high-pressure water directly at the seabed for demanding offshore intervention operations. By locating the pump subsea, the system maximizes jetting efficiency while reducing deck space, mobilization time and personnel exposure to pressurized equipment.
Providing up to 2,500 bar operating pressure, the system can operate as a standalone unit or be integrated with the Deep C HD Subsea Dredge. It supports a wide range of applications, including excavation, internal cleaning, concrete cutting, high-pressure testing and other complex subsea intervention tasks.
