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.
Today’s challenges of erosion, flooding and storm surges are primary concerns for coastal communities around the world. Traditional coastal engineering solutions, such as concrete seawalls or rock breakwaters however, will become unsustainable due to their limited resilience, higher costs, societal impacts and unwanted ecological side effects. In response to these challenges, Coastbusters developed a nature-based solutions approach to sustainable coastal management. These solutions will create new habitats based on known ‘biobuilder species’ in the form of biogenic coastal reefs. The purpose of the reefs is to induce natural accretion of sand, attenuate storm waves and reinforce the foreshore against coastal erosion, thus adding to coastal protection.
From an early fascination in oceanography, nature has played a defining role in the career of Dr Todd Bridges. With a decade’s investment in the Engineering With Nature® initiative, he has seen that sustainability and engineering can go hand-in-hand providing economic, environmental and social benefits. His focus now is to build on that foundation – to encourage and facilitate collaboration across sectors, public and private, to advance and accelerate Engineering With Nature practice.
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.
At Deltares in the Netherlands, a research team is developing a portfolio of technologies dedicated to the management of the finest and most challenging fraction of soft sediments. These technologies may unambiguously be called nature based because they make use of natural processes to enhance dewatering and strengthening, induce flocculation and the settling of fines, and protect the muddy bed from erosion.
Managing sediments, especially from dredging, is important for the management of estuaries and coastal areas. When implemented in the right way, a sediment management strategy can be qualified as a nature-based solution as it uses the physical processes of erosion and sedimentation to create added value. There is a need for an evaluation of sediment strategies and the habitats that are created for a wider range of objectives than only biodiversity and nature conservation. The concept of ecosystem services provides this broader framework.
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.
Dredging is essential for the maintenance and development of ports, harbours and waterways to allow for safe navigation, remediation and flood management. The process, which relocates large volumes of sediment, can be accompanied by the release of suspended sediments into the water column referred to as sediment plumes.
ReefGuard, a mobile coral breeding facility provides a highly controlled environment to aid in integrating the breeding and outplanting of corals. This article gives a detailed look into how proven small-scale coral breeding techniques can be scaled-up and applied in practice to promote environmental gain around marine infrastructure projects.
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.
Underwater sound from anthropogenic sources and its potential adverse effects on the marine environment is a topic of much global interest. This article gives an overview of known sound source levels for various dredging equipment and activities and describes a method used to extrapolate source levels.
Dredging for a new port complex in a remarkable, protected marine environment required adherence to very specific thresholds and an intensive Environmental Management Plan (EMP) that included mobile monitoring as well as daily visual observations of turbidity levels around the dredging works and the disposal zone.
