Safety Award 2018 Winner: Van Oord Debris Removal Platform

To promote innovations within the realm of safety within the dredging industry, the International Association of Dredging Companies gives a Safety Award to an exemplary programme, procedure or project each year. Announced at the IADC’s Annual General Meeting, the winner of the Safety Award 2018 is Van Oord’s Debris Removal Platform. Van Oord changed the existing technique of manually removing debris to an automated system, reducing the risk of personal injury.

1DH Model Predicts Transport and Sedimentation Inside a Hopper

A one-dimensionalhorizontal modelling tool which accurately predicts the overflow of sediments and bed layer distribution inside the hopper of a Trailing Suction Hopper Dredger is introduced.

Trailing Suction Hopper Dredgers

“Facts About Trailing Suction Hopper Dredgers” describes self-propelled hydraulic dredgers with drag heads that suction up loose materials like sand.

Validation of the Tass System for Predicting the Environmental Effects of Trailing Suction Hopper Dredgers

Models created by researchers using innovative software have been tested and validated by monitoring trailers during dredging operations.

Dredging Rock with a Hopper Dredger: The Road to the Ripper Draghead

Research, investigations into pickpoints and cutting geometries, predictive models and trials were essential in constructing a ripper draghead that could be placed on a TSHD.

New possibilities for Ripper Dredging of Rock

When the trials at the Port of Sudan to open a trench with explosives were unsuccessful, trenching equipment – a backhoe dredger with a rock bucket and a TSHD with a new generation of ripper-draghead – was brought in to accomplish the task.

Irruption of the Trailer Jumbo in the Dredging Industry

The newly built "jumbo" trailing suction hopper dredgers - ranging from 17,000 to 34,000 m3 capacity - have expanded the capabilities of the dredging industry enormously.
