Can a preliminary model describe CSD spillage due to centrifugal advection?
Can a preliminary model describe CSD spillage due to centrifugal advection?

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.

Safe Disposal of Dredged Material in a Sensitive Environment
Safe Disposal of Dredged Material in a Sensitive Environment

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.

Conceptual Model for Partnering in the Dredging Industry
Conceptual Model for Partnering in the Dredging Industry

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.

An Analytical Approach to the Sedimentation Process in Trailing Suction Hopper Dredgers
An Analytical Approach to the Sedimentation Process in Trailing Suction Hopper Dredgers

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.

A Computationally Efficient Model for Predicting Overflow Mixture Density in a Hopper Dredger
A Computationally Efficient Model for Predicting Overflow Mixture Density in a Hopper Dredger

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.
