The International Association of Dredging Companies (IADC) is the global umbrella organisation for contractors in the private dredging industry: an industry that makes the world a safer, better and more sustainable place to live. IADC is driven to help that industry move forward with a variety of activities and publications, all of which can be found on this website.

50 years anniversary edition

This year marks 50 years of Terra et Aqua. To celebrate this milestone, a special anniversary edition was published in May 2022. This one-off special will take the place of both the spring and summer issues, with the regular autumn and winter editions following later in the year.

Latest issue

Terra et Aqua is a quarterly publication which aims to disseminate knowledge accrued by global dredging professionals as well as solutions to issues facing the industry. Issues of Terra et Aqua feature articles covering dredging projects as well as the topics of safety, socio-economics, technical innovations and the environment.

Climate Risk Overview tool: mapping naturebased flood protection opportunities

The planet is facing enormous challenges caused by human activity, increasing the vulnerability of communities and ecosystems to the forces of nature. This is worsened by the effects of climate change, which is threatening the world’s coastal defences. Van Oord has responded to these challenges by developing the Climate Adaptation Action Plan. The plan is designed to encourage meaningful dialogue between stakeholders in order to provide ready-to-scale marine solutions that help increase the resilience of the communities and ecosystems of coastal areas.

Submissions for IADC’s Safety Awards 2022

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 2022 Safety Awards, IADC’s Safety Committee received 11 submissions. Each one is assessed on five different categories; sustainability; level of impact on the industry; simplicity in use; effectiveness; and level of innovation.

Estimating sediment erosion of a centrifugal dredge pump’s impeller

Sediment erosion is a phenomenon of mechanical wear of components that decreases efficiency and uptime of the dredging process. Dredge pumps are designed to handle mixtures of water and solid particles with varying particle size from less than 0.002 mm to greater than 200 mm. A dredge pump’s overall effectivity in the field depends upon its uptime. Uptime is influenced by the number of times the pumping process is interrupted, which can be due to maintenance combating the material loss, clogging, etc. This research deals with the erosion phenomena by considering a framework of numerical models, capable of qualitative and quantitative erosion estimation, coupled with experiments for validation. Coordinate Measurement Machine (CMM) is used for surface roughness measurement before and after the experiment, thus depicting the material loss due to erosion.

Seminars & Courses

To optimise the chances of the successful completion of a project, contracting parties should, from the start, fully understand the requirements of a dredging project. IADC’s seminar strives to provide an understanding of the basics of dredging through lectures and workshops which are given by industry experts in a classroom setting for a hands-on experience.

MEMBERS

IADC has over a hundred main and associated members.
