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.

Suez Canal: the first of many projects for the iconic waterway

Starting in 1955, Ackermans & van Haaren helped modernize one of the world's most important waterways: the Suez Canal. Over six years, the company participated in a series of dredging and widening campaigns at Port Said, the Great Bitter Lake, and the southern section of the canal, excavating millions of cubic meters of material and helping create new bypass channels that improved navigation.

As one of the world's most critical trade routes, the canal carried much of the oil destined for Europe. The works formed part of a broader program to widen, deepen, and improve the route, allowing larger vessels to pass more efficiently between the Mediterranean and the Red Sea. Between 1955 and 1961 alone, Ackermans & van Haaren contributed to bypass, widening, and deepening projects involving more than 19 million m³ of dredging works.

These early projects marked the first chapter in a long Suez story. Over the decades, the company would return repeatedly to help modernize one of the world's busiest and most strategically important waterways.

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.
