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.

1988

Thailand’s gateway to the world

During the late 1980s, Thailand stood at the threshold of significant economic transition. As the country opened to international trade, there was a vital need for a modern deep-water port infrastructure. For DEME, this period coincided with a broader recovery across the global dredging sector following an extended downturn. And the contracts secured in Thailand would ultimately prove pivotal both to the nation’s maritime capacity and to DEME’s international expansion plans.

The centerpiece of this program was the construction of Laem Chabang, which was Thailand’s first deep-sea port. DEME dredged a 2.5-kilometer access channel to a depth of 14 meters, reclaiming substantial tracts of land, and contributing to extensive coastal infrastructure.

Therefore, what was once a modest fishing settlement rapidly developed into Thailand’s primary maritime gateway. Nowadays, Laem Chabang ranks as the leading port in Thailand. And DEME didn’t stop there. It also subsequently expanded the ports at Sattahip and Map Ta Phut, laying the groundwork for the region’s rapid industrialization and sustained growth.

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.
