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.
For production, sand quality and environmental reasons predicting the amount of the so-called overflow losses when using a trailing suction hopper dredger is very important.
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.
