IADC is dedicated to not only promoting the skills, integrity and reliability of its members, but also the dredging industry in general. IADC has over one hundred main and associated members. Together they represent the forefront of the dredging industry.
IADC’S MISSION IS:
- to inform the world about the fundamental need for dredging and the economic, social, technological and environmental benefits thereof;
- to improve the international business climate for the private dredging industry;
- to promote fair contract conditions and fair competition within the dredging markets;
- to promote worldwide the Standards of Professional Conduct which form the basis for all members’ operations;
- to promote the industry as an innovative industry with attractive career opportunities.
In order to fulfil IADC’s mission IADC assumes five important roles:
IADC aims to serve as a quality label. It encourages its members to establish common standards and a high level of conduct in their worldwide operations. In this context, IADC assists in the implementation of sound tendering practices and the use of standard contract conditions for the industry. And IADC also supports sound environmental practices and the use of representative classifications systems for dredging equipment and for soils and rocks.
IADC represents the common interests of its members at supra-governmental and legislative bodies, international non-governmental organisations, international conferences and exhibitions. IADC even assists in the conceptualization of treaties and conventions relevant to the dredging industry. Specifically IADC defends the interests of its members regarding intellectual property. More generally, IADC promotes free competition, the opening up of protected markets and the conversion of state-owned authorities into private entities, and private/public cooperation.
IADC seeks to establish dynamic co-operation amongst parties involved in dredging. Specifically, between international companies and local dredging companies, and between private companies and public authorities. IADC also organises international conferences and seminars for third parties or assists such parties in organising dredging-related events.
IADC promotes the field of dredging as a career choice. In co-operation with educational institutions, IADC organises dredging seminars, assists in developing dredging-related curricula, and presents awards to students and other young people. In general, IADC supports the development of dredging-related educational materials for all age groups.
IADC publishes and supports the publication of literature and audio-visual materials pertinent to dredging, aimed at a variety of target groups.
The International Association of Dredging Companies is the trade association for international private dredging and maritime construction contractors. The dredging industry is a highly competitive industry. Still, international contractors share common interests as expressed in IADC’s mission. To represent these interests, IADC was established in 1965 by the main international dredging contractors at that time.
IADC is an association according to Dutch law. The Dutch legal system recognises the constitutional right of association and of assembly. As a trade association, IADC is a non-profit-making organisation and the fees from membership contributions are intended to cover the necessary expenses of operation. The work of IADC is accomplished through working groups of experts drawn from member companies and through its Secretariat.
IADC’s General Meeting gathers annually and forms the legislative body of the Association. IADC is governed by a Board of Directors with representatives of different member companies.
During his distinguished career as professor of Coastal Engineering at Delft University of Technology (TU Delft), Kees d’Angremond served as head of Hydraulic and Offshore Engineering, chair of the department of Hydraulic and Geotechnical Engineering, and dean of the faculty of Civil Engineering from 1989 to 2001. Now professor emeritus, he still works as an advisor and independent consultant. We invited Kees to a conversation with Stefan Aarninkhof, professor of Coastal Engineering and chair of the department of Hydraulic Engineering at TU Delft, to talk about their careers in the dredging industry and the role of academia in the industry today.
The use of nature and natural processes is an innovative way to increase water safety and create added value through nature development and recreation. This exploratory study provides an initial inventory of the impact and costs of existing Building with Nature projects in the Netherlands. It also includes an analysis of the decision-making process in choosing this type of project and identifies success factors. Building with Nature projects deliver added value but often also involve additional costs compared to traditional reinforcements. These costs give an indication of what we as a society are prepared to pay for the development of nature and recreation as part of hydraulic engineering projects.
Climate change and increasing environmental damage are demonstrating the urgency of transformation to a sustainable global economic model. The implementation of the sustainable development concept tends to narrow to integrating environmental, social, and economic concerns in the decision making. In economics, the definition of such concerns is an externality that represents the divergence between social and private costs. This study investigates the available sustainable asset valuation methods that can include the externalities materialised in maritime infrastructure projects and compares them based on economic, social and environmental criteria.
In today’s world, expectations for sustainable practices are fast becoming the norm. Countries, the public and communities are requesting transparency, the application of higher environmental standards and involvement in decision-making processes when new developments in a marine environment are proposed. Marine infrastructure projects not only require environmental permits and works licences to be in place, they also need a Social Licence to Operate (SLO). This article describes the social licence in this fast-changing context of information and technology, and explores tools that can be used to develop a ‘responsible project’ and provide a successful and sustainable outcome for society and the environment.
Over the past decades, there has been a growing interest in exploring innovative ways to minimise the environmental footprint of coastal developments and in nature-based approaches for shoreline protection. At Mubarraz Island near Abu Dhabi (UAE), an international oil company beneficially reused ~12 million m³ of dredged material to protect pipelines, construct a causeway and create mangrove habitat to manage coastal erosion. This ‘Working with Nature’ approach has provided a cost-effective nature-based solution for shoreline protection, with added benefits for biodiversity conservation.
In June 2019, the research team of the LIFE MARINAPLAN PLUS project began operating the first-of-a-kind demonstration plant installation at the harbour entrance of Marina di Cervia (Italy). Fulfilling the project’s objective to apply at industrial scale a reliable technology for the sustainable management of sediment in marine infrastructures, this technology prevents harbour silting through the use of submerged devices called ‘ejectors’ installed on the seabed.
Stéphanie Groen works as the Director of Coastal & Climate Change, Asia for Aurecon. Based in Singapore, she was appointed to the position at the beginning of 2020. Previously, Stéphanie was involved in marine and environmental projects for more than 15 years with DHI and her education is in civil engineering and business administration. IADC also knows Stéphanie as the winner of the Young Author Award in 2007. More recently, she was appointed as a committee member to the prestigious FIDIC Sustainable Development Committee. We were interested to hear more from Stéphanie – her views on sustainability, the collaboration with the dredging industry through FIDIC and what her new role can mean for sustainable water infrastructure projects.
At present too little use is made of the opportunities that the design and construction of land reclamation offer for the underground storage and recovery of fresh water. The managed aquifer recharge systems in the coastal dunes of the Netherlands are a good example of successful subsurface water storage. And it is to be expected that the sandy deposits of land reclamations could serve a similar purpose. This in turn will contribute to a sustainable development of land reclamations.
Armed with degrees in both Marine Engineering and Engineering Economics as well as 35 years – and counting – of experience at the Panama Canal Authority, Ilya Espino de Marotta has blasted through the glass ceiling wearing a pink hard hat. Amongst the diverse roles she has under her belt, ranging from Marine Engineer in the shipyard to Vice President for Transit Business, Ilya has notably led the Canal’s expansion as head engineer and now oversees operations from the second highest position at the authority.
A paradigm shift is being increasingly embraced within the dredging industry. The traditional engineering approach is becoming a holistic approach in which the ecosystem is leading and values for people, profit and planet are integrated in an interdisciplinary manner.
Building with Nature is an innovative approach that combines natural processes with innovative engineering methods to realise sustainable projects. Permeable dams are being utilised as part of a Building with Nature solution to help restore the eroding mangrove-mud coast of the Demak district in central Java, Indonesia.
March 10: panel session hosted by IADC, CEDA and PIANC at the UN Science, Policy and Business Forum on the Environment in Nairobi. The UN Science, Policy and Business Forum on the Environment will convene its second global session in Nairobi, Kenya, from March 8-10, 2019 in the lead up to the Fourth Session of the UN Environment Assembly. The forum’s work is aligned with the theme of the assembly: Innovative solutions for environme
Presentation: ‘Hondsbossche and Pettemer Sea Defence an example of sustainable asset valuatio’ by Sven Kramer (Van Oord) − Director Sustainability
This presentation shows the practical implications of taking all externalities into consideration as early as possible in a project procedure. It is complex but asset valuation is gradually becoming more and more feasible for large infrastructure projects. The independent International Institute of Sustainable Development carried out a study on the benefits of “Nature Based” coastal Protection compared to traditional “Grey” solutions. Their report is expected to be published mid-November 2021.
Presentation: ‘There is ”more” in maritime infrastructure‘ by Marc Huygens (DEME) − Environmental Manager
There are opportunities to develop and implement new solutions for maritime infrastructure challenges. In addition to technical-economical values there is a big commitment to create both environmental and social values. To take the industry to the next level it is necessary to attract students and young professionals to the industry to ensure all externalities are taken into consideration from the onset of a project. The “Social Benefits Wheel” is a tool that can help track the degree to which a project or programme is attaining its social development targets and goals.
Presentation: ‘Sand as a Resource’ by Jan Fordeyn (Jan De Nul) − Director Project Development & Conceptual Design
In our day to day lives most of us are not aware of how many industries rely on sand as a part of their working process. The amount of sand consumed has dramatically increased over the last few years and this can be largely contributed to the world wide construction boom. How is this going to affect us in the future?
A contribution by Polite Laboyrie, President of CEDA, to the Paving the Waves 2020 conference is linked to the IADC-CEDA book Dredging for Sustainable Infrastructure. The book and also Mr Laboyrie’s presentation presents guidance to achieve dredging projects that fulﬁl their primary functional requirement, while adding value to the (natural and socio-economic) system.
Webinar (replay): The Multiple Benefits of the Hondsbossche and Pettemer sea dunes, valued by the SAVi methodology
This webinar is especially of interest for policymakers, infrastructure developers, investors and other stakeholders with an interest in green infrastructure. But also for both technical and non-technical professionals in dredging-related industries like consultants and advisors at port and harbour authorities, offshore companies and other organisations that execute dredging projects.
