Efficiently remove soil plugs to allow internal cutter access
Internal pile dredging removes debris, hard sediment or clay soil plugs, allowing the pile to be cut below the seabed by an abrasive internal pile cutter.
Our internal dredging system is ideal for both installation and decommissioning, as well as other applications.
It has been designed to work in conjunction with either the R300 dredging system or an airlift. The combination of high-pressure/high-flow water jets and vacuum/suction has proven very effective.
The system can be deployed by a diver or an WROV – or, when an airlift is used, by a crane with optional assistance from an WROV.
- Covers pile sizes from 20.3" to 122", from subsea/submerged piles to jacket legs
- Ideal for both installation and decomm
- Combines with our mechanical and water-abrasive cutting and recovery technologies for the complete decomm package
