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.

1906

Pioneering in Argentina and Bahía Blanca dredging

When works began in Argentina, groups of Dutch and Belgian workers boarded ships bound for a long journey to South America. The voyage was not without risks - on one crossing the dredger Rosario II sank en route, though fortunately everyone on board was safely rescued.

But DEME’s early pioneers were undeterred. After weeks at sea, Buenos Aires marked the start of a life far from home, followed by long journeys upriver to places like Rosario and Bahía Blanca, where they lived on anchored vessels or in small riverfront quarters.

The workers created a thriving community, held together by camaraderie and defined by the rhythm of the river. Their innovative spirit and resilience shaped the future of our work across continents, and the foundations they laid still carry us forward today.

From 1906 to 1911, the dredging fleet played a central role in developing the Bahía Blanca port area, supporting both the commercial harbor of Ingeniero White and the emerging railway and naval facilities in nearby Puerto Belgrano. During these works, more than 8 million m³ of soil was dredged, with 7 million m³ used for land reclamation, reinforcing the rapid expansion of this strategic port. Bucket dredger Antwerpen and tug Marguerite were deployed throughout the operations.

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.
