A new, innovative way of using the Robotic Crawler.
For cut execution, the crawlers will be fitted with Abrasive Water Cutting Nozzles, which will penetrate the tubular using a mixture of sand and water jetting at ultra-high pressures. Ultrasonic measurements will verify the completeness of the cuts.
This method improves safety and efficiency since
the cutting sequence is done without using divers as the operations is controlled from a control container
an ROV can relocate the crawler within the jacket structure to cut at various locations
you avoid the risk of a wire being stuck under the weight of a platform while cutting

SubC used the abrasive water cutting in the summer of 2020, as a part of Tyra Redevelopment in an innovative decommissioning operation of monopiles.
