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 five-day 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.


Since 1993, IADC has provided a five-day-long seminar especially developed for professionals in dredging-related industries. In addition to basic dredging methods, new equipment and state-of-the-art techniques are explained through the seminar’s programme. Often realised in co-operation with local technical universities, the course has been successfully presented worldwide.



The topics addressed by the seminar make it ideal for attendees meeting the following conditions:

  • (Starting) Employees of Dredging contractors,
  • Engineers,
  • Consultants,
  • Environmental consultants,
  • (Future) Decision makers and their advisors in governments,
  • Port and Harbour authorities,
  • Off-shore companies and
  • Other organisations that have to execute dredging projects.



All presentations and workshops are given by lecturers who are experts in the field of dredging. The team of lecturers rotates and consists of the following experts:

  • Royal Boskalis - Pieter den Ridder and Gerben de Jong
  • Jan De Nul - Stefan Bruggeman
  • DEME - Paul Vercruijsse and Luk Verstraelen
  • Van Oord Dredging and Marine Contractors - Robert Dijkema and Marcel van den Heuvel



Spanning five days, the programme addresses the following specified topics during lectures and workshops:

  • overview of the dredging market and the development of new ports and maintenance of existing ports;
  • project phasing (identification, investigation, feasibility studies, design, construction, and maintenance);
  • descriptions of types of dredging equipment and boundary conditions for their use;
  • state-of-the-art dredging and reclamation techniques including environmental measures;
  • site and soil investigations, designing and estimating from the contractor’s view;
  • costing of projects and types of contracts such as charter, unit rates, lump sum and risk-sharing agreements;
  • design and measurement of dredging and reclamation works;
  • early contractor involvement.



The seminar includes a site visit to dredging projects or a shipyard.


Jameson who joined the seminar in 2023:

“The seminar has benefited me as it was very insightful, engaging and exhilarating. In significance was the site visit which has provided us with a holistic view of a major dredging and reclamation project. The icing on the cake has been the assignment on the dredging and landfill project which has enhanced my understanding on the tender and contract aspects. This has allowed all of us to work alongside and learn from one another coming from various fields. I have truly befitted from the lectures.”



By request of USA's Marine Technology magazine published by SNAME, an article written by Ria van Leeuwen of IADC about the Dredging and Reclamation Seminar was published in the January 2024 issue. This article provide an overview of the seminar held in Manilla in October 2023 and give an overview of what companies can expect their employees to gain by taking the course.
