Dredging group Van Oord has ordered two water injection dredging vessels at Dutch yard Kooiman.
The new vessels will be multifunctional and will include systems to give a wider range of deployment. The first vessel will be commissioned in late 2020. Several new technological developments have also been applied to the design, such as heave compensation and dynamic positioning, which means that the dredging can be pre-programmed to a great extent and so performed more efficiently. Thanks to high manoeuvrability
and very limited draught, the vessels are suitable for maintenance dredging in shallow harbours. The vessels will be equipped with a hybrid energy management system. They will be able store energy in batteries from residual heat that is normally lost. This energy is subsequently used for purposes including propulsion. Diesel-electric engines will reduce CO2 emissions. The craft will comply with the new IMO Tier III legislation for reducing harmful NOx emissions and take account of EU Stage V legislation.
