Van Oord has successfully carried out beach nourishment works along the coast of the Dutch province of Zeeland. As a result, the coastline has been stabilised and coastal towns and infrastructure are well protected for the coming years.
The work was carried out by Van Oord's three new hopper dredgers, including the Vox Alexia, which was christened in September. During the project execution, the vessels were powered by LNG, a more sustainable fuel. The project is part of the Coastline Care programme of Rijkswaterstaat, the executive agency of the Dutch Ministry of Infrastructure and Water Management.
To reinforce and protect the coast of Zeeland, Van Oord carried out sand replenishment at the Westkapelse Zeedijk and Nieuwvliet-Groede. The hopper dredgers were used to collect sand from the seabed and pump it through a pipeline to the beach. On the beach, weather and wind will ensure further spreading and will enable the dunes to grow. In this way, the coast is being reinforced with the help of nature's own forces. At the Oostgat shipping channel, the channel wall was replenished, i.e. the channel just offshore was partly backfilled with sand. Because the channel is now not as close to the shore, less sand disappears from the beach and the coastline stays in place longer.
In total, approximately 4 million cubic metres of sand were applied. This is important not just for the safety of the coast but also for preserving nature conservation areas, opportunities for recreation, and drinking water extraction.
