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.

1990

Remarkable courage of the hostages of Umm Qasr

Few episodes in DEME’s 150-year history demonstrate the resilience of its people more vividly than the events that unfolded in Iraq in 1990.

While working on a major dredging project near Umm Qasr, a team from Dredging International had become stranded following Iraq’s invasion of Kuwait. The cutter suction dredger Mascaret was deployed on the project, which aimed to improve Iraq’s access to the Persian Gulf.

Dredging International’s team were part of a group of 26 Belgians caught up in the escalating Gulf Crisis, turning what began as a challenging international project into a months-long ordeal.

As diplomatic efforts intensified, a breakthrough came when two of the 14 colleagues were granted permission to leave Iraq and were repatriated. For the remaining 12, uncertainty continued. Isolated on a residential platform off Umm Qasr, they endured months of tension as the prospect of war drew ever closer. Throughout the ordeal, solidarity among the team remained strong.

Finally, in December 1990, the remaining 12 colleagues were released and flew home to Belgium. Their arrival at Brussels Airport was an emotional moment. They were welcomed by the entire management team, shareholders, many colleagues, and family members who had anxiously awaited their return for nearly six months. According to eyewitness accounts, the loud applause that erupted when their aircraft left Iraqi airspace remained one of the defining memories of the entire ordeal.

The extraordinary story was later chronicled in the book Gegijzeld in Irak by J. De Bremaeker, ensuring that this remarkable chapter in DEME’s history would not be forgotten.

More than three decades later, the story remains a powerful reminder that DEME’s legacy is built not only through ambitious projects around the world, but also through the courage, and perseverance of its people in the most challenging circumstances.

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.
