Jan De Nul’s giant TSHD pumps sand onto Knokke beach

Over the past five weeks, Jan De Nul dredged as much as 500,000 m³ of sand to elevate the beach of Knokke-Heist on behalf of Agentschap Maritieme Dienstverlening en Kust (MDK).

JDN’s trailing suction hopper dredger (TSHD) Pedro Álvares Cabral – sailing on 100% second-generation biofuel – carried out the sustainable dredging and beach replenishment works along the Belgian coast.

This reduced the vessel’s CO₂ emissions by 80% to 90%.

In order to protect the Belgian coast, Jan De Nul raised the beach by pumping ashore a large quantity of sand.

This way, the company kept the shape of the coastline intact in a natural way.

The site office is highly energy-efficient because of its green energy supply.

“We are currently investing heavily in a renewal of our huts for all sites. After this investment boom, only eco-site huts will be part of our infrastructure,” said JDN.

The CO₂ emissions achieved on this project are 88% lower than the reference footprint.
