Dredges for Sale
Due to the exhaustion of economic reserves, we have the following bucketline dredges for sale. These are good, well maintained modern dredges built only in 1980’s.
The design of the dredges, especially in respect of the maximum digging depth, bucket capacity and treatment plant can be varied to suit the client’s requirements.
OCIE will undertake to dismantle the dredge and transfer (ship) the dredge assemblies to the country of operation. OCI personnel will undertake the re-erection and commissioning of the dredge at the mining site. Training and operation of the dredges can also be provided.

The transfer of used modern dredges is a very cost effective approach in acquiring bucketline dredges. Substantial saving is achieved by this method. The reconstructed dredge will give many years of trouble free operation as evident by P T Koba Tin’s experience with their transfer of two big capacity dredges.
