TSHD Hegemann V gets SCHOTTEL RudderPropellers

The new trailing suction hopper dredger (TSHD) Hegemann V will be equipped with SCHOTTEL RudderPropellers.

“Due to its relatively short length of about 75.9 metres in combination with the SCHOTTEL RudderPropellers, the vessel will be optimally manoeuvrable even in narrow rivers,” said the Spay/Rhine headquartered manufacturer of steerable propulsion systems.

Currently under construction at Kooiman Marine Group, the dredger is designed to execute multiple types of dredging activities at specific locations.

The propulsion system of the TSHD consists of 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, the company said.

With medium-sized rudder propellers such as the SRP 270, SCHOTTEL is meeting new challenges in the international maritime market.

These include shifted engine power classes, new ice class rules and the growing trend towards electric or hybrid-driven vessels.

The Hegemann V was developed by Kooiman Engineering, part of Kooiman Marine Group, in close collaboration with Hegemann Dredging.

With a suction pipe on the starboard side and an inboard dredge pump, the vessel is able to fill the 1,500 m³ hold with silt or sand.

“When unloading through a row of bottom doors, the vessel must be manoeuvred and positioned precisely. In addition, the material 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,” SCHOTTEL said.

The 75.9-metre-long and 15.8-metre-wide dredger is designed for worldwide operations on a 24/7/365 basis and is managed by a crew of eight.

The dredger, being built for German Detlef Hegemann Aktiengesellschaft, is scheduled for delivery in July 2022.
