The channel thrusters can be used for main, as well as auxiliary, propulsion systems. Channel thrusters are driven electrically, hydraulically, or by means of a diesel engine. Installed in the bow or stern, channel thrusters considerably improve the vessel’s manoeuvrability, and alternatively act as a brake force thruster or emergency (main) propulsion unit.
Verhaar Omega’s channel thrusters are recommended over Transverse Tunnel Thrusters for auxiliary propulsion, especially in the case of inland waterway vessels with a shallow draught: predominantly river cruise vessels, inland waterway barges or pontoons, double-ended ferries, river dredgers and landing craft.
Verhaar Omega’s channel thruster features an integrated horizontal propeller/impeller that pumps water from under the vessel, inward, through a channel at the centre of the unit. Once inside the propeller channel, the water flow is deflected through a rotating drum, which determines the direction of thrust, into outlet channels. As the drum is 360° rotatable, clockwise or counter-clockwise, the thrust force and direction can be controlled accurately within a short response time. The channel thrusters, available in a range from 100kW up to 1500kW, can be fitted with two, three or four outlet channels, depending on the requirements.
The Verhaar Omega channel thruster accommodates two separate drive units: one for the propeller, and another for the rotating drum. This unique design eliminates any risk of oil spills or water contamination by grease.
