The OTTer in short

Royal IHC's OTTer is a range of compact dredgers as platform for deploying the well-known IHC TT-Pump. This provides customers with a modular, compact and cost-effective solution to dredge slurry for smaller dredging projects. Examples are ponds, tailings, dams, rivers, canals and small harbors.

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.
