![]() This equipment enables the vessel to conduct its own seabed assessment activities prior to dredging meaning that it doesn’t have to rely on any other survey-dedicated vessels.Īquadelta was christened on 25 August 2022 at the Port of Rotterdam, where it had been carrying out its first dredging operations, cleaning the berth of the Cruise Terminal Rotterdam in view of the arrival of Queen Mary 2. With this in mind, Aquadelta has been fitted out with its own survey equipment, including a multi-beam echo-sounder. Having accurate and up-to-date survey data at your disposal is essential for an efficient water injection dredging operation. Conoship designed the vessel with future-proofing in mind, keeping plenty of room in both the layout and the deadweight for future conversions, including the future installation of alternative fuels or battery systems. Much attention has been given to the vessel's interior to make it user-friendly and comfortable, with accommodations available for a crew of six. ![]() The vessel is equipped with two 320kW electric-driven water injection pumps which can reach a dredging depth of 27m, while a dynamic positioning system and an unlimited sailing area allow for versatile operations spanning large seaports to shallow waterways. The vessel is over 48m long, has a breadth of 12m, a design draught of 2.3m and a gross tonnage of 497.Īquadelta has a diesel-electric propulsion arrangement that includes five Paccar-DAF MX-13 390kW engines driving two 450kW thrusters to propel the dredger to a speed of 10 knots. The engineers of Van der Kamp have, with substantial input from the crew, used their wide experience of WID operations to make an optimal design for the new dredger, taking into account dredging efficiency, ability to work under a variety of conditions and capability for quick mobilisation to new projects. The other two, Maasmond and the new Aquadelta, are both managed by the main company. ![]() At present, it owns four units of this type, with two being managed and operated by the German affiliate company Meyer & Van der Kamp Akke, in service since 1984, and Jan, which was converted from a mussel dredger in 2012. Van der Kamp has a long tradition of using WIDs in Western Europe, mainly The Netherlands, Germany and the UK. The vessels was built at Scheepswerf Bijlsma shipyard in Wartena. Conoship International designed the vessel in close cooperation with Van der Kamp’s engineers. It is an efficient and environmentally sound way of maintaining the depth of navigation channels, rivers and ports.Įarlier this year Dutch dredging and contracting company Van der Kamp commissioned the building of a WID, later named Aquadelta. This eliminates the need for traditional excavation techniques and the subsequent transportation of sediment material. WIDs dilute sediment by injecting water into the subsoil, creating a density current which naturally moves the sediment away from the dredged area to deeper areas. These dredgers - most suited for dredging silts, clay particles and fine sands - are a cost-effective and environmentally friendly option, with their high work rate meaning faster completion of projects and a lower carbon footprint compared to conventional dredging. Throughout 2022 several companies have commissioned the building of water injection dredgers (WIDs). Not a member yet?
