Van Oord has decided to use the option for a third trailing suction hopper dredger at Keppel FELS. The vessel[ds_preview] is similar to the two units ordered in May 2018. Each one has a hopper capacity of approx. 10,500m3. The new hoppers will replace existing vessels and fit in with Van Oord’s aim of making its fleet more energy efficient. The climate control system on board will utilise the vessel’s cooling and heating sources to recycle energy. The ship’s automated systems will be more advanced than ever before, and integrated vessel data is being processed by a shore support centre. The vessels will obtain a Green Passport and Clean Ship Notation. The first two vessels, Vox Ariane and Vox Apolonia, will be delivered in 2021. The third vessel will be delivered in 2022.
