Launched in 1972, Terra et Aqua is a quarterly journal that aims to disseminate knowledge accrued by global dredging professionals as well as solutions to issues facing the industry. This year marks 50 years of the publication and, in place of the spring and summers issues, we’re celebrating with a special anniversary edition in May.
ABOUT TERRA ET AQUA
Articles investigate and explain the latest innovations relevant to emerging and established professionals immersed in the dredging industry and its related sectors.
RESOURCE TO THE DREDGING COMMUNITY
Supported by the IADC, Terra et Aqua represents IADC's commitment to the highest standards of professional conduct in the dredging industry.
WRITTEN BY EXPERTS
Ground-breaking developments within the dredging industry are discussed by professionals, specialists and researchers engaged in the industry’s activities. With expertise from all over the world, authors are encouraged to submit articles for publication in Terra et Aqua.
Staff Director Engineering and Estimating (Van Oord)
“The Terra et Aqua is one of the few magazines in our field of work that provide truly in depth articles on a variety of subjects, often based on scientific studies, and very relevant for dredging professionals.”
HR Wallingford Limited
“Real insights, whether it’s technical, policy or people……whether you have 5 minutes or 50 minutes, it’s always worth picking up.”
Ocean & Coastal Environmental Consulting (Craig Vogt Inc)
“The new Terra et Aqua Journal is “spot-on”. The Journal is easy to navigate and continues to bring forth pertinent articles enlightening us of technical details on dredging projects as well as informing us on policy-related areas, such as the recent Journal that presented sustainability principles for marine infrastructure.”
Frank Verhoeven, President of IADC, shares his thoughts on todays’ issues related to the dredging industry and introduces the articles in this issue of Terra et Aqua.
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.
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.
During marine transfers, it is essential to achieve a maximum level of control. With the bollard step, Jan De Nul has designed a simple solution to enhance safety during transfers of crew and visitors. This innovative idea came from the crew of the multicat DN46 and was picked up during an Operational Control meeting, where an advisory board discusses suggestions that improve the safety and efficiency of the company’s operations. ‘We stimulate all possible innovative ideas within our company’, says Quinten Schaumont, Area QHSSE advisor. ‘At all levels, at all times.’
IADC’s Safety Committee and Board of Directors awarded the very first Safety Award to a supply chain organisation active in the dredging industry to Keppel FELS. The company was praised by the committee for the results of its safety programme and commitment to safety onsite. Anchored in Keppel Offshore & Marine’s Safety Plus Programme and Singapore’s National WSH Vision 2028, Keppel FELS continues to consistently improve and enhance its existing Health, Safety and Environment (HSE) management systems.
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.
This high-level report explores what is needed in order to improve the connection between green-labelled funds and sustainable waterborne infrastructure projects.
