Precision subsea WROV powered excavator and tool-carrier system

The Scancrawler system is a tool-carrier for hydraulically operated tools. It has been
developed specifically for medium to heavy operations requiring high accuracy.
Typical tasks:

  • Subsea excavation
  • Rock dump and drillcut removal
  • Pipeline deburial
  • Relocation of seabed
  • Removal of grouting

The unit is interfaced, powered , and controlled by the Clients work-class ROV. Operation and maintenance is performed by the Clients ROV team in tandem with Scanmudring specialists.
All power and controls are transferred between the unit and the ROV by subsea mating.
The unit may be wet stored.
The systems may be operated from live platforms and vessels, and is designed for rapid mobilisation.
The Scancrawler combines advanced ROV technologies with the design of rugged land based construction machines.
