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.

1977

New horizons in the Gulf region

In the aftermath of the 1973 oil crisis, infrastructure investment slowed across much of Europe. But elsewhere, new horizons were emerging. Across the Gulf region, ambitious plans for ports, coastal infrastructure, and industrial development created many fresh opportunities.

As maritime trade expanded, the Port of Dammam in Saudi Arabia faced severe congestion, prompting a major expansion program between 1975 and 1980. DEME, as part of a joint venture, played a central role in the port’s transformation. The joint venture dredged an extraordinary 48 million m³, creating a 400-meter-wide navigation channel capable of accommodating larger vessels.

Extremely challenging soil conditions pushed both people and equipment to their limits, with the cutting tools wearing down at a staggering rate. On cutter suction dredger Reina Fabiola alone, crews replaced up to 500 cutter teeth per day, supported by a dedicated team of on-site welders.

With the nearest repair port more than two weeks' sailing time away, self-reliance was essential. Teams tackled several emergencies with remarkable ingenuity, from repairing hull damage on the Antwerpen IV, to lifting a damaged tug directly out of the water.

The Dammam project led to further opportunities in Saudi Arabia, including important developments in Jubail on the Gulf coast and Yanbu on the Red Sea. The Dammam chapter reflects many of the qualities that still define the company today: bold engineering, resilience in the face of adversity, and the determination to succeed far from home.

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.
