Hi-Traq tracked trencher

The Hi-Traq trencher offers unrivalled manoeuvrability and traction capabilities for shallow water operations

Royal IHC’s Hi-Traq features a unique self-levelling suspension system for the installation and burial of power cables. It is able to endure the harsh environments typically found at offshore wind farm locations.

  • Traversing, steering and trenching on slopes of up to 20⁰
  • Self-levelling system maintains stable operations and consistent depth
  • 10m radius trenching capability
  • Four independent tracks ensure smooth break-over points

Reliable platform for seabed intervention

The award-winning Hi-Traq has been specifically designed to address the issues encountered on previous offshore wind cable lay projects where varying soil conditions have led to project delays. In its trenching configuration, Hi-Traq features multiple tooling options that facilitate both jetting and mechanical cutting operations.

The mechanical cutter chain provides maximum operational efficiency while minimising pick wear. In addition, we have developed a tooling suite for a number of IRM requirements. 

Tracked subsea vehicle for a wide range of activities

Although specifically developed for the offshore renewables industry, challenging environmental design requirements have led to the production of a very capable vehicle, scalable to a range of activities across a myriad of subsea environments. From a jetting-only lightweight variant to a heavy multi-tool vehicle, Hi-Traq can be used for a range of burial activities involving power cable or pipelines, and flowlines or umbilicals.

A demonstration vehicle was constructed in 2014, which was subjected to a rigorous testing process that effectively showcased the capabilities of the design.
