Archeology

VAT - Vehicle Assisted Tool is a name for a family of custom built tools for underwater work. The tools are more than a simple rotary cutter or manipulator; the tool includes sensors and are independent of the support ROV to varying degrees. A good example is a hydraulically latching blanking plug used to temporarily shutoff a water intake such that the upstream most valve can be serviced. A typical application is on the face of a hydroelectric dam on a service water intake. The blanking plug is installed and removed by an ROV. While the plug is in place, sensors in the tool monitor the hydraulic latching mechanism and seal integrity for the safety of the personnel working on the valve.

Underwater Tooling - Underwater tools deployed with ROV's include rotary cutters, high pressure water cleaning jets, manipulators, and latching devices for connecting lift lines to recover objects that are underwater.
