ROTECH SUBSEA TRENCHING & EXCAVATION

  • The Rotech Subsea (RS) is a suite of highly effective subsea excavation tools deployed over the side of a vessel and operated remotely from its deck.
  • The technology is based on the principles of producing a controlled column of water, the pressure of which fluidises the seabed and effectively excavates a trench.
  • It is a non-contact system which minimises the risks associated with physical contact especially around complex subsea assets.
  • The Trenching and Excavation Equipment, operated by Rotech Subsea, is designed by Rotech Engineering and built in-house.
  • Some of the common applications include:
  • Cable Array and Export Trenching / De-burial
  • Cable Joint Burial / IRM
  • Pipeline, Umbilical & Flowline Trenching / De-burial / Recovery
  • Backfilling for Cable / Pipeline Protection
  • Jack-up Leg / Spud Can Clearance
  • Harbour / Pontoon Seabed Clearance
  • Sandwave Clearance / Cable & Pipeline Route Clearance
  • Salvage De-burial / Access
  • Access to Subsea Structures / IRM / Decommissioning
  • Drill Cuttings Removal
  • Rock Removal / Relocation & Dispersal
