Schottel RudderPropellers for new TSHD

Currently under construction at Netherlands-based Kooiman Marine Group, the Hegemann V is designed to execute multiple types of dredging activities. Owing to its relatively short length of 75.9 metres, the vessel will be manoeuvrable even in narrow rivers.

The propulsion system comprises two Schottel RudderPropellers type SRP 270 (840 kW each), featuring fixed pitch propellers with a diameter of 1.85 metres. The azimuth thrusters will be driven by diesel-electric systems to fulfil strictest emission requirements.

Scheduled for delivery in July 2022, the Hegemann V was developed by Kooiman Engineering in collaboration with Hegemann Dredging. With a suction pipe on the starboard side and an inboard dredge pump, the vessel is able to fill the 1,500m³ hold with silt or sand which can be pumped by one or two dredge pumps connected in series either with discharge connections on both sides of the vessel or via a bow connection.

Measuring 75.9 metres by 15.8 metres, the dredger is designed for worldwide operations on a round-the-clock basis and is managed by a crew of eight. To maintain ports and waterways, it will also be able to load up to 1,930 m³ with lower densities.
