Equipment
Drill rigs
DCC has chosen for MHWirth pile top drill rigs. The PBA drill rigs are robust and very reliable. These drill rigs have operated in arctic and dessert environments.
DDC owns several types of drill rigs, including the PBA 1450, which was built in cooperation with MHWirth as a flagship model.
Reverce Circulation Drilling
Reverse Circulation Drilling (RCD) also known as airlift, is a system which brings the cuttings to the surface. Compressed air is injected into the drill pipe below water level, just above the drill bit. Because off difference in density the mixture of water, air and cuttings is flushed out of the drill string through the discharge.
