underwater pipe cutting

The C-JET powers subsea waterjet cutting tools capable of cutting through 250 mm steel. Shown here is a prototype of Chukar's Zip-Tide™ outer diameter pipe cutting system.

cutting multiple layers of grouted casing

Chukar's C-JET 3000 safely and efficiently cuts multiple strings of grouted casing, including strings with voids in the grout.

3LPP Removal with Water Jet

Chukar's C-JET 3000 blasts away the toughest coatings including 3LPP!

Operable to 3000 Meters (10,000 Feet)

Effective at cutting steel up to 250 mm thick or waterjet blasting at pressures up to 3800 bar, this powerful self-contained 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’s subsea waterjet equipment has numerous applications for deepwater emergency response operations, salvage operations, and rapid de-mobilization operations. Chukar systems quickly blast away even the toughest coatings, including three-layer polypropylene (3LPP), and provide a safer, more effective method for cutting multiple strings of grouted casings for well severance. 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 of Mexico spill, when the company was asked to rapidly manufacture a system to clear a clogged containment system 1500 meters underwater.
