ROV-Deployed Waterjet

ROV deployed waterjet
Sub-Jet 3000 ROV-deployable waterjet system

The SUB-JET 3000 is deployed as an underslung equipment skid on a work class ROV and is powered from the ROV's auxilliary HPU.

underwater waterjet cutting

The Sub-Jet provides 55,000 PSI (3800 bar) ultra-high pressure water and abrasive to a variety of subsea UHP waterjet tools, including waterjet pipe cutting systems.

3LPP Coating Removal

Chukar's SUB-JET 3000 quickly blasts away the toughest coatings, including 3LPP or 3-Layer polypropylene.

Abrasive water cutting multi string casing

The SUB-JET 3000 safely and effectively cuts multiple strings of grouted casing, including improperly grouted casing with voids.

Operable to 3000 Meters (10,000 Feet)

By customer demand, Chukar Waterjet has developed an ROV-deployable subsea waterjet system.

Like the C-Jet Subsea Waterjet Skid, the ROV-deployed SUB-JET 300 is effective at cutting steel up to 250 mm thick or waterjet blasting at pressures up to 3900 bar.

The SUB-JET 3000 is deployed as an underslung equipment skid on a work class ROV and is powered from the ROV's auxilliary HPU.  

This 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’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.
