T1 Trencher

Enshore T1 - Subsea to Onshore Hard Ground Trenching

T1 is a trenching system that works both subsea and onshore. We can adapt T1 to operate in cutting and jetting mode, for multiple soils and various environmental conditions.

  • Unique offshore and onshore capability

  • Variable modes for enhanced burial

  • Simultaneous cable / pile laying and burial

  • Trench depths to 1.3m in wheel cutter mode

  • Trench depths to 2.0m in jetting mode

Enshore T1 Trencher

Cutting and Jetting

With 520kW of power, Enshore’s T1 trencher provides enhanced burial at depths of up to 1.3m in cutting mode and 2.0m in jetting mode.

Supported by teams who understand the many challenges of making a transition from subsea to onshore, T1 is the ideal equipment solution for flow lines, pipeline burial, and umbilicals and power cables on the beach, in the surf and offshore.
