The LIFE MARINAPLAN PLUS project is the first-of-a-kind demonstration plant at industrial scale of an innovative solution for the sustainable management of sediment in marine infrastructures. In June 2019, the research team of the LIFE MARINAPLAN PLUS project began operating the plant installation a
After dredging operations, a lot of sand and silt is lost from the Rhine-Meuse estuary into the sea or into depots. In order to retain the dredged sand and silt in the natural system of the Rhine-Meuse estuary for as long as possible, a number of major players in this field have got together in [&he
Testing of equipment installed on FSUE “Rosmorport” vessels, the hopper barge Rabochaya and dredger Redut, is underway as part of the unmanned navigation project, the Russian company informs. The aim of the project is to introduce unmanned navigation of the Independent Non-Profit Organization MARINE
The Environment Agency has presented a report of the trial tests of a new approach to beach replenishment at Poole Bay. The report revealed results of a year-long programme of fieldwork to monitor the behaviour of sand deposited in the nearshore zone off Canford Cliffs in Poole Bay. The technique of
Bakker Sliedrecht has just announced their plan to begin a research in order to determine whether biodegradable oil can be used in the submersible motors that the company has supplied for equipment of Van Oord. If this is applicable, the international marine contractor wants to use this type of oil
In the winter issue of IADC’s scientific journal Terra et Aqua, an interesting article was published about the development of the Smartsediment Ecosystem Services QGIS tool. As reported, this tool enables users to make a first numerical evaluation of the impact of sediment management on ecosystem se
Since the days of Jules Verne, many have dreamt of mining minerals from the bottoms of the oceans. Over the years, Royal IHC has developed a vast range of equipment based on innovative ideas. Many of them were used in challenging circumstances and at ground-breaking depths. With leading roles in the
The Chittagong Port Authority and HR Wallingford have signed a contract that engages its expert hydraulics engineers to study navigation at the Bangladeshi port. Around 90% of Bangladesh’s international sea trade is handled by the port, which is seeking to welcome larger vessels. The signing ceremon
In the latest edition of the Terra et Aqua magazine, International Association of Dredging Companies (IADC) presented an interesting story on the ‘Monitoring of Settling and Consolidation of Mud after Water Injection Dredging in the Calandkanaal’. As regular maintenance and relocation of sediment de
Licencing of dredging activities is based on environmental analysis, including measuring levels of contamination. The contaminated dredged materials may upset the ecosystem balance at their disposal site. In these cases, officials take actions before the licence is granted. The types of contaminants
The Hunze en Aa’s water authority and Ecoshape recently built a 40-metre-long test dike in front of the sea dike on the Dollard. For the construction of the test dike the contractors used clay taken from the clay ripening plants that processed sediment from the seaport channel of Delfzijl and the Br
Deltares has just revealed the first results from the study of sand erosion under the Frisian Wadden Sea coast. The company is conducting this study with Wetterskip Fryslân, the Frisian water authority, and Fugro. The study is about the piping failure mechanism (sand erosion below dikes) on the Fris
Emission reduction is one of the biggest innovation challenges for the maritime industry. In recent years, this was mainly driven by the implementation of strict emission regulations, such as the IMO global sulphur limit. As a result of the Paris Agreement, the focus is shifting towards the reductio
International Association of Dredging Companies (IADC) recently released a new article titled “Numerical investigation of the head and unsteady flow characteristics of a dredge pump loading high-concentration sands”. The article presents research which numerically simulates the unsteady water flow a
