Chukar Waterjet offers underwater waterjet cutting and blasting equipment capable of operating at depths in excess of 3,000 meters. Effective at cutting steel up to 250 mm thick or waterjet blasting at pressures up to 3,800 bar, Chukar’s powerful underwater waterjet cutting and blasting system improves the safety and effectiveness of subsea operations and has numerous advantages over conventional subsea cutting and cleaning tools, giving operators increased flexibility and access to larger projects. Unlike conventional tools, waterjet cuts without heat, reducing the hazard of igniting trapped pockets of gas during cutting. In addition, the tools used in a waterjet system cannot bind in the cut, jeopardizing asset integrity.

 

Chukar said its subsea waterjet equipment has numerous applications for deepwater emergency response operations, salvage operations and rapid demobilization operations. It can be used to blast away coatings and marine growth to inspect welds, or as a cutting tool in emergency response and salvage operations. Waterjetting equipment also may be used to provide turbulence in a stream of methanol for hydrate remediation, an application Chukar developed in emergency response to the Gulf oil spill, when the company was asked to rapidly manufacture a system to clear a clogged containment system 1,500 meters underwater.
