The Hydro Digger - Advanced Underwater Excavation System

10

Fisher Offshore’s HydroDigger, together with its integrated Launch and Recovery System (LARS), provides a safe, secure and highly effective solution to subsea excavation. Deployed over a vessel side and operated remotely from its deck, the HydroDigger works by producing a controllable column of water, the pressure of which effectively excavates the seabed. This minimises or eliminates the risks associated with physical contact, especially around complex subsea assets. By employing real-time sonar monitoring, the HydroDigger enables precision excavation both within constrained areas and over long distances.  This category contains movie files showing a typical excavation scenario.
