Trenching speeds can vary depending on mode (tracked or skid), soil conditions, product diameter and the required depth of trench required, however speeds in sand over 400m/hr can be attained where speeds of 80-150m/hr are achievable for conditions where the soils are stiffer and harder to penetrate.
The directly coupled water pumps together variable speed drives means that this 1200Hp system is equivalent to that of a conventional electro-hydraulic 1500Hp system that uses the power to water pumps less efficiently.
The CFD modelled plenum takes the water from the pumps to the jet legs with minimal losses.
The water system is designed to maximise water pressure and flow at the adjustable jetting nozzles which are distributed on the jetting swords to fluidize in front and between the swords, and if required to taper the trench wall.
Its these design enhancements, coupled with unrivalled burial experience that puts the T-1200 and the T-1500 jet trenching systems as the most effective burial systems in their class.Download brochure
