International Dredging Review

International Dredging Review
MENUMENU

Van Oord has ordered the construction of two water injection vessels at Kooiman Marine Group. The first vessel will be commissioned in late 2020.

This new generation of vessels has water injection dredging, mass flowing and power jetting systems. The vessels also have heave compensation and dynamic positioning.The vessels are suitable for maintenance dredging in shallow harbors due to limited draft and efficient maneuverability.

The new water injection vessels will be equipped with a hybrid energy management system. Consequently, the vessels can store energy in batteries from residual heat that is normally lost. This energy is then used for purposes including propulsion. Diesel-electric engines will reduce CO₂ emissions. The new water injection vessels will comply with the new IMO TIER III legislation for reducing harmful NOx emissions and take account of EU STAGE V emissions legislation.
