Cutting, trenching and backfilling system

The I-Trencher is a self-propelled and highly manoeuvrable tracked machine that has been designed with three primary modes of operation: cutting using digger chains, open V-cut trenching, and backfilling.

All three operations are performed using digger chain assemblies – proven mine-based technology – instead of cutting and transporting soil. 

The I-Trencher is capable of excavating a two-metre deep trench in a single pass at a maximum water depth of 1,500m. 

Trencher for both cables and pipeline burial

The I-Trencher was developed for Canyon Helix and is one of the most widely utilised tracked trenchers in the world, having completed numerous pipeline protection projects. Although originally intended for pipeline burial, this tracked trencher has also proven itself in the cable burial market.

In addition, the I-Trencher has been used extensively for the installation of inter-array and export cables at a number of North Sea wind farms.
