A presentation at the upcoming Underwater Intervention show in New Orleans will highlight recent advancements in subsea waterjet technology that enable deploying waterjet cutting and blasting equipment at depths of more than 3,000 meters. These advancements are said to present new opportunities for rescue, salvage, rapid demobilization and other deepwater operations.
 
Scheduled for January 25 at 3:30 p.m. in room 217, the presentation will be conducted by Bruce Kivisto, general manager of subsea high-pressure waterjet equipment manfuacturer Chukar Waterjet (St. Michael, Minnesota). The company’s waterjet equipment is effective at cutting steel as thick as 250 mm and blasting at pressures as high as 3,800 bar. This makes it useful for applications ranging from blasting away coatings and marine growth for weld inspection to heavy cuts needed in emergency response and salvage operations. The equipment can also be used to provide turbulence in a stream of methanol for hydrate remediation.
 
Among other topics, Mr. Kivisto will discuss the advantages of such equipment compared to conventional subsea cutting and cleaning tools. For example, according to Chukar, tools used in a waterjet system cannot bind in the cut and jeapordize asset integrity, the company says. Waterjet cutting also reduces the risk of igniting trapped pockets of gas during cutting.
