Fit for purpose
Royal IHC's OTTer is mainly used to dredge medium sand, silt and gravel. It combines the advantages of the IHC TT-Pump unit into a single dredging solution. The design is based on the principles of production maximisation and reliability. Its cost-effective design reduces the need for specialised maintenance personnel.
The OTTer is a modular deployment system for the range of IHC TT-pumps and comes in two versions. The first type is used for dredging loosely compacted soil. In this vertical deployment configuration, the TT-Pump is fitted with a sand production head and jetting water nozzles and is suspended from an A-frame and lowered under gravity to the dredge surface. The standard pontoon system can deploy the TT15, TT20 and TT24 pumps and by adding two additional pontoons to the front, the system can also deploy the bigger TT30 and TT35. Dredging depths of 50m and beyond are possible in this configuration, making hard to reach areas easily accessible.
The second type utilises a ladder to deploy the TT-Pump, which is fitted with a rotating cutter head and can be used in combination with the TT20 and TT24 pumps. This version is suitable for more compacted soil conditions and for dredging depths up to 10m deep.
Applications of the OTTer
- construction or heavy mineral sand mining
- alluvial gold or diamond mining
- oil sands mining
- environmental dredging
- inland waterways and canals maintenance dredging
- reservoir dredging or power plant maintenance
- tailings and slimes dams.
