Discover 150 years of DEME!

In 2026, DEME celebrates 150 years of marine and environmental engineering. From our early roots in 1876, we have grown from our origins in dredging and marine works into a leading, diversified group - shaped by expertise, innovation, resilience and a constant drive to push boundaries. 

Throughout this anniversary year, we’ll take you on a journey through our history, sharing stories and moments that show how challenges were approached, solutions were developed and ambitions kept moving forward. Across our channels and on this dedicated anniversary website, you can discover the people, projects and breakthroughs that made DEME what it is today. This website will be updated weekly with new stories. Throughout the year, we will use #DEME150 to share and connect these stories. 

As we reflect on 150 years, we continue to look ahead with the same spirit that defines us: We Care. We Dare. We Deliver.

In the years following the Second World War, the fleet underwent a period of steady evolution. New dredgers entered service, and steam engines increasingly gave way to diesel power. This gradual transition reflected broader technological developments across the maritime industry and marked a new chapter in dredging.

More reliable, efficient, and easier to operate, diesel-powered dredgers offered greater operational range and improved productivity. These advantages became increasingly vital as projects grew in scale and the company expanded beyond its traditional home markets.

This shift from steam to diesel helped shape the fleet that supported growing international ambitions in the decades that followed. It stands as one key step in a long tradition of technological evolution that continues to define DEME today.

With 150 years of history, there are countless moments to tell. In this anniversary year, we share a non-exhaustive selection of stories that illustrate how DEME became the company it is today. These stories are drawn from a variety of historical sources, including books by authors such as Dirk Podevijn and Mon Vanderosteyne, company publications and the input of colleagues across the organization. As this website looks back on 150 years of heritage, it features archival material from different eras. Safety standards and working practices have evolved significantly over time and should be understood in their historical context.
