Royal IHC's OTTer is mainly used to dredge medium sand, silt and gravel. It combines the advantages of the IHC OTTer-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 OTTer-pumps and comes in two versions. The first type is used for dredging loosely compacted soil. In this vertical deployment configuration, the OTTer-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 150-, 200- and 250- OTTer-Pumps and by adding two additional pontoons to the front, the system can also deploy the bigger 300- and 350-pumps. 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 OTTer-Pump, which is fitted with a rotating cutter head and can be used in combination with the 200- and 250- OTTer-Pumps. This version is suitable for more compacted soil conditions and for dredging depths up to 10m deep.
