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
Dredge Yard today released a video of its new DrillCutter testing that ensures less spillage, less turbidity, and environment-friendly cutting while increasing the productivity of the dredger. The DrillCutter prototype was tested on a CSD500 dredger in the coastal waters of the Arabian Gulf. Compact
Rohde Nielsen A/S is introducing new dredgers Ask R and Embla R into the dredging market. According to the Copenhagen based company, these are probably the most innovative and environmentally friendly split trailing suction hopper dredgers (TSHDs) ever built.

On May 7th, Stefan Aarninkhof (Professor Coastal Engineering TU Delft) will host the symposium from their corona-proof studio. The symposium will start with a plenary session where Henk Nieboer (director
A dyke made of the clay from the clay ripeners (Kleirijperij) near Delfzijl is currently being tested in the Delta Flume of Deltares. A full-size cross-section of the dike has been constructed in the flume and is being subjected to the conditions of a superstorm. The tests are part of an extensive s
IADC – International Association of Dredging Companies will host a webinar next month on the importance of managing financial risks in a dredging project. In this webinar – set for May 4 – the topic of managing financial risks will be linked to the Brisbane Airport dredging and reclamation project.
Van Oord has signed a three-year agreement with ABB Turbocharging to provide fleetwide maintenance and optimization services.
