20 YEARS OF THE FIDIC BLUE BOOK: A CONTRACT FOR THE DREDGING INDUSTRY
The publication of the FIDIC Form of Contract for Dredging and Reclamation Works, commonly referred to as the Blue Book, marked a significant moment in the evolution of contracting within the marine infrastructure sector. First issued as a formal edition in 2006 following an earlier test version in 2001 and subsequently refined in the second edition published in 2016, the Blue Book represents one of the few genuinely industry-specific standard forms of contract developed for global use.
SUBMISSIONS FOR THE 2026 IADC SAFETY AWARD
When individual employees, teams and companies view everyday processes and situations through a continuous lens of safety, they can each contribute to making all aspects of operational processes, whether on water or land, safer. For the 2026 Safety Award, IADC’s Safety Committee received 12 submissions. Each one is assessed on five different categories; sustainability; level of impact on the industry; simplicity in use; effectiveness; and level of innovation.
DYKE REINFORCEMENT TIEL-WAARDENBURG: LESSONS IN ZERO- EMISSION DEPLOYMENT
Water and flood protection are existential concerns in the Netherlands, a country where much of the land lies below sea level and dykes are part of the everyday landscape. Maintaining and upgrading these defences is a permanent, large-scale undertaking and one that has traditionally been highly carbon intensive. The dyke reinforcement project between Tiel
and Waardenburg demonstrates that this does not have to be the case. Drawing on field studies and interviews with the project team, this article examines how the Mekante Diek consortium (Ploegam, Dura Vermeer and Van Oord) approached zero-emission execution at scale and the lessons the wider industry can draw for accelerating the transition to more sustainable infrastructure delivery.
TOWARDS MANAGING A GROWING DEMAND FOR MARINE SAND
The demand for marine sand for coastal nourishments is set to increase rapidly. At the same time, marine resources and space are finite and shared with other uses such as wind farms, shipping and protected marine habitats. The combination of rising demand and restricted supply leads to scarcity as an emerging challenge in the long-term management of sand extraction. Despite geographic proximity, Belgium and the Netherlands experience and manage sand scarcity in different ways, providing valuable lessons for long-term resource management worldwide. The research project BANX supports the management of sand extraction from tidal sandbanks by developing knowledge and tools.
