- Facilitate contacts within and outside the dredging community
- Enhance the public image of dredging
- Each association has a diverse membership encompassing corporations, professionals and stakeholders, from many different fields, who represent a range of disciplines and all aspects of the product supply chain.
Members include manufacturers, universities, research institutes, regulators, consultants, dredging companies and public authorities, working in the dredging, navigation, coastal and inland flood protection, deepsea mining, offshore wind energy, oil and gas production fields, and providers of a broad range of services such as brokers, insurers, financiers, lawyers and many more.
