Splash Zone Riser, Conductor, Caisson & Leg Cleaning

Ultra high pressure water jetting services in marine environments

"Diverless" remotely operated water jetting services - improved safety, cost effectiveness, efficiency & quality

Cleaning subsea structures and assets in the splash zone can be a challenging part of maintaining production critical assets such as pipelines. iasgroup has designed, developed and operated a variety of fully automated remote tooling (ROT) systems using high and ultra high pressure water for the removal of marine growth, concrete and other protective coatings from structures. Our systems are capable of both linear and circumferential passes, exposing existing profiles.

If inspection is also a requirement, our splash zone tooling is able to provide cleaning and NDT (high resolution visual or ultrasonic testing) inspection all in the one process. iasgroup continue to set new standards for cleaning in marine environments.

Benefits

  • ROT improves cost effectiveness and safety - removes divers, dive support vessels and dive spreads
  • ROT allows for improved quality as it is fixed in position and is not weather dependent - can operate in large swells and tidal movements
  • Our ROTs can provide for complimentary services such as NDT inspection, whether visual through high resolution cameras or utilising the latest ultrasonic technology. The NDT equipment is integrated onto the tool allowing us to clean and inspect in the one process.
  • ROT has the capability of full vacuum recovery, for environmentally friendly removal of contaminants and debris
