OPERATION
& DEPLOYMENT
|
|
|
| Deployment floats are rigid floating platforms used to move about and launch the submersible cutting tools, referred to as demolition rings. These items are scaled to the size of the pier or caisson being sectioned. Moving equipment from pier to pier is accomplished using a work boat or crane. |
 |
|
Both the deployment float and demolition ring are hinged to open on one side allowing for easy placement around a pier. Once in position, the ring is closed and locked to create a continuous track which allows the cutting heads to rotate cleanly around the full perimeter of the pier. |
 |
| Using a motorized cable system, the demolition ring is lowered to the required cut height (generally at the mud line) where pneumatic grippers are then engaged, locking the demolition ring firmly into position at the base of the pier. |
 |
|
Jogging the robotics through the desired motions programs the system for the cutting operation. After ensuring the cut path is appropriate, the operator accepts the path and monitors the cutting process from a hand held console. Water pressure, garnet flow and cutting speed can all be adjusted remotely. Once initiated, the cutting process is silent. Little evidence of operation is visible. |
