Kooiman to build 1500-m3 trailing suction hopper dredger Hegemann V

Kooiman Marine Group will design and build a new trailing suction hopper dredger for Detlef Hegemann Aktiengesellschaft. The ship is designed to execute multiple types of dredging activities on specific locations.

The Hegemann V has been 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, it can load the 1500-cubic-metre hold with silt or sand. Unloading the dredged material can be done by opening a row of bottom doors. In addition, the material can be pumped by one or two series-connected, dredge pumps with discharge connections on both sides of the ship or via a bow connection at the front.

The dimensions of the vessel are: 75.90 x 15.80 x 5.50 metres. In order to also maintain ports and waterways, it is able to load up to 1930 cubic metres with lower densities. In addition, its length is relatively short and with two rudder propellers it is optimal to manoeuvre at small rivers.

‘It all fits exactly in the box, as if it is a design optimised for standard/series construction,’ says Project Manager of Kooiman Engineering Peter Vrolijk. ‘Some things will have to happen before we can start sea trials. Kooiman Engineering will firstly have to finish the design. Consequently, we can do a lot of the work ourselves, for example the ship’s interior, hull outfitting and finishing at one of our three yards. In addition, we have a number of reliable suppliers.’
