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
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.

PRODUCT HANDLING |
|||
|
Wheel Cutter |
Product is carried from the front mounted bell-mouth over the top of the vehicle, through trough assembly, to wheel cutter. Bellmouth fitted with feeler assembly to assist in monitoring cable catenary during simultaneous lay-trench operations. |
||
|
Jetter |
Product passes underneath Trencher between tracks before passing through jet legs into fluidised trench. Bellmouth fitted with feeler assembly to assist in monitoring cable catenary during simultaneous lay/trench operations. Depressor can be fitted between jet legs to ensure positive depth location when trenching flexible products. |
