Coastal Port Dredging Project of the Year Award for Jan De Nul

Jan De Nul Group has won the DPC ‘Coastal Port Dredging Project of the Year Award’ for its sustainable approach in port dredging, the company said in their latest release. 

From August 2017 to April 2018, Jan De Nul Group dredged 4 million m³ of mudstone in the Port of Linkou, Taiwan, and re-used the dredged sediments to extend the nearby port of Taipei by means of reclamation.

In order to be able to dredge and reclaim these quantities within the set period, a cutter suction dredger (CSD) and a trailing suction hopper dredger (TSHD) worked simultaneously on this project: the cutter pre-cut the hard mudstone after which the hopper dredged the sediments and transported them directly to Taipei Port for reclamation.

Pre-cutting of mudstone with a cutter and subsequent dredging and reclaiming with a hopper on this scale was unprecedented.

This simultaneous working method also required the operations to be perfectly synchronized to enable joint production optimization, which was vital to execute this huge pre-cut scope efficiently and on time, said Jan De Nul.

This award was presented yesterday, during a ceremony in Amsterdam, the Netherlands.
