Depending on its size and installed power, a Cutter Suction Dredger is capable of cutting a wide range of soil types. Although precise and relatively efficient, a CSD can spill significantly. The authors propose a preliminary model which describes spillage due to centrifugal advection.
A state-of-the-art 3D plume model, used at the Ras Laffan Port Expansion project, simulates alternative disposal scenarios and helps develop Safe Disposal Maps.
Partnering can be a tool for increasing co-operation and sustainability during high-risk maritime construction and dredging projects. A model helps to determine when and if applying partnering is appropriate.
A number of theories are used (Camp, Groot, Miedema and Vlasblom, Yagi, Braaksma, Ooijens and van Rhee) to determine the overflow losses when loading trailing suction hopper dredgers. The model derived here has several important improvements, including the speed of doing the calculations.
Creating accurate models for the prediction of overflow losses by trailing suction hopper dredgers is an invaluable tool in determining the feasibility of land reclamation.
This study analysing changes in the bottom-topography at dredged material disposal sites and the interaction between disposed matter and the surrounding density currents received the IADC Award at the CEDA Dredging Days.
An IADC "Most Promising Student" Award has been presented to a graduate of TU Delft for her work on determining the magnitude and direction of wave-induced sediment transport.
An IADC "Most Promising Student" Award has been presented to a graduate of TU Delft for his thesis which describes the dynamics of hopper loading both in simulation and as compared with actual measurements onboard a TSHD.
