ENS1600 TRENCHER

Enshore ENS1600 - Advanced Seabed Trenching

ENS1600 is a dual mode tracked trencher with a proven track record for burying pipelines, flowlines, umbilicals and submarine cables. Typically, ENS1600 is fitted with a subsea power kit, but we can also configure this trencher to work in shallow water, being surface fed from a support vessel.

  • Adapts quickly to operate in multiple modes

  • Simultaneous cutting and jetting operations

  • Backfill attachment

  • Trench depths up to 3.2m cutting and 5.0m jetting

  • Crane or A-Frame Launch

ENS1600 - Advanced Seabed Trenching

Cutting and Jetting

Depending on your project, ENS1600 can operate in 3.2m chain cutting mode and up to 5m jetting mode with backwash capability. This offers flexibility for burial projects: ENS1600 can be configured to work in simultaneous cutting and jetting mode, or to provide jetting only.

This makes ENS1600 the ideal trencher for all sectors delivering seabed infrastructure, be that oil and gas pipelines, power transmission cables, offshore renewables or cables on the beach, in the surf or offshore.
