Water-jet Cutting (C-Cut)

Key features

  • Precision cutting at a distance and in confined spaces

  • Simultaneous cutting of multiple materials

  • Minimum secondary contamination

  • Reduced plant downtime

  • No heat affected zone

  • Small equipment footprint

A new standard in decommissioning – BHR Group and OMS

BHR Group’s fluid engineering expertise and OMS’ unrivalled precision manipulation experience combined to deliver a new standard in decommissioning.

Cutting technique for hazardous environments

The DIAJET (Direct Injection of Abrasive Jet) is a cold-cutting technique providing powerful and accurate cutting and cleaning for hazardous environments where challenges such as limited access, minimal secondary contamination and heat need to be managed carefully.

 The DIAJET technique creates a slurry suspension of solid particles into a high-pressure water jet of 100 - 1,000 bar. This approach creates a cutting performance up to five times greater than entrainment water-abrasive cutting techniques.

 Using OMS’ precision manipulator technology, the DIAJET cutting head can be deployed in hazardous environments with restricted access, ideal for complex decommissioning challenges in the oil, gas and nuclear sectors.

Water jet cutting – vital applications

  • Cutting munitions for explosive ordnance disposal

  • Removal of structural steel and pipework for nuclear, subsea or topside decommissioning

  • Cutting leg piles from offshore oil platforms

  • Cutting of pipework and tanks for plant maintenance

  • Removal of contaminated and corroded surfaces
