Cable burial typically takes place in notoriously harsh shallow water environments, that have high seabed drag and lift forces generated by strong currents and wave action. Traditional technologies have often struggled with such demanding conditions and this has led to project delays and increased costs.

The Hi-Traq® Jetter has been developed to tackle these shallow water environments and uses the successful ‘Royal IHC Hi-Traq® Multi Tool Trencher’ as its design foundation. The Hi-Traq® Jetter uses the same field proven Royal IHC patented 4 track under carriage system, which provides unparalleled performance over difficult terrain such as undulating sand waves and sloped seabeds.

The new Hi-Traq® Jetter provides 1200kW of power in a compact and light weight package. The vehicle weighs only 20Te and is capable of burring Ø450mm products into 3.3m trenches. The vehicle is built up in modules that can be rapidly taken apart and re-assembled allowing for shipping of the full vehicle in a single 40’ container.

Customer benefits 

  • low cost mobilisation
  • designed to be shipped in containers
  • track driven system allows for Increased operational window
  • faster trenching in wider range of soils
  • greater flexibility in route planning due to large travel suspension and auto levelling system.

Key technical features

  • operates in high currents and waves
  • trenches tight radii found on 2nd ends
  • traverse steep sand waves and boulders
  • 4 track ensures no sudden pitching over seabed terrain.
