Hydro Abrasive Cutting for Pipes, Piles & Structures

Cutting underwater and in tidal zones using hydro abrasive tooling

Leader in designing and delivering customised remotely operated cutting tools underwater

iasgroup has been developing and deploying subsea hydro abrasive cutting technologies for close to 20 years. We have unmatched knowledge and experience in delivering remotely operated tooling (ROT) for subsea and splash zone hydro abrasive cutting.

Our ROT is particularly useful when cutting is required from the inside of the structure due to limited external access, or beneath the mud line where mechanical cutting tools are not able to operate.

The capability and experience of our engineering and operational personnel is second to none and ensure that our diverless ROT are able to optimise productivity, safety and cost.

We are able to offer customised tooling or existing proprietary tools, depending on your maintenance, serverance or decommisioning needs.


  • ROT hydro abrasive cutting is particularly beneficial where mechanical tools cannot access - where external obstructions exist or the cut is required below the mud line
  • ROT improves cost effectiveness and safety - removes divers, dive support vessels and dive spreads
  • Increased accuracy and versatility - precision cutting of any shape of almost any material and thickness
  • Flows and pressure outputs can be adjusted and controlled for optimum efficiency
