THSD Yed-Prior conducts sea-trials


Over the past few weeks, TSHD dredger Yed-Prior successfully completed her initial sea-trails from IJmuiden port.

The Yed-prior, formally known as container vessel “Gerd”, was converted by Spaansen Marine Aggregates into a 5300 m3 sand& gravel dredger.

For this vessel conversion project, HollandMT was awarded the contract to supply the 850 mm dragarm system, including a 2000 kW submerged dredge-pump, innovation moon-shaped gantries and electric dragarm winches. The dredging system enables efficient dredging up to – 40 m.

The dredger is expected to enter service for Spaansen in October.

On behalf of HollandMT, we wish Yed-Prior and her crew a safe and pleasant voyage.

HollandMT receives PO from Kooiman/Hegemann

In early August HollandMT received a purchase order from Kooiman Shipyard for design and supply of the dredging system for Trailing Suction Dredger Hegemann V.

The Hegemann V has been developed by Kooiman Engineering, part of Kooiman Marine Group, in close collaboration with Hegemann Dredging and HollandMT.

With the dragarm installed 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 6 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 in small rivers.

For this project HollandMT will supply the dragarm system, loading and unloading system including dredge-pumps, all dredge-pipe lines, gate-valves, bottom doors and bowcoupling. HollandMT will also provide the degassing system and all dredge-instrumentation.
