Hard rock beds which can't be pulverized efficiently by dredging vessels, like cutter dredgers and dippers, can be pulverized by explosives.
Holes are drilled in the rocky bottom with tophammers and air-driven down the hole hammers.
After the holes are drilled, the holes will be loaded with explosives and blasted.
TMS designed several drill rigs which can be used on pontoons and jack-ups.
The drilling rigs are designed containerized and can be transported worldwide easily.
