Jet Trenching

DeepOcean operates an advanced fleet of jet trenching systems, with assets capable of operating in tracked mode for firmer seabed conditions to free flying mode for softer conditions.

The jet trenchers are designed for manoeuvrability and rapid deployment providing an efficient and cost-effective solution for the burial, trenching and maintenance of rigid and flexible pipelines, umbilicals and power cables.

UT1

UT-1 is the world’s most powerful free flying  jet trenching system with 2.1MW of total power. It is also fitted with sophisticated drive motors, which allow precise control of pressure and flow, giving a high degree of flexibility when undertaking workscopes in varied environmental conditions and a competitive edge. It can be configured to lower either flexible or rigid products up to a trench depth of 3m and 1.2m wide, UT1 has the additional capability to create an open empty trench profile using its powerful eduction system to facilitate specific pipeline burial specifications. The UT-1 is permanently integrated onto the  the multi-role subsea construction vessel, Volantis, it has with a state-of-the-art heave compensated launch and recovery system, which includes a submersible latch beam, cursor and high speed constant tension winches. This offers unparalleled flexibility in severe environmental weather conditions offering high Sea State deployment

 

 

T1000

The T1000 is an advanced Jet Trenching  system capable of operating in free flying or tracked mode in water depths to 2000m, the trencher  has  1000 Horse Power (750kW) of subsea power & has  a 3m maximum burial capability for burial of cables, umbilicals and flexible pipes. The adjustable 3m jet tool allows for varying diameter products and splice burial whilst downward facing nozzles provides capability for burial in all cohesive soils (up to 80kPa) and all sand grades. Equipped with a High Sea State LARS Launch and Recovery system, the T1000 can be deployed in harsh weather conditions with up to 4.0m significant wave height. The T1000 is permanently mobilised onboard the Havila Phoenix subsea construction vessel.
