Van Oord has ordered two trailing suction hopper dredgers with a hopper volume of approximately 17,000 m3. Spanish Construcciones Navales del Norte S.L., LaNaval, will build the ships at its yard in Bilbao. Both vessels will be delivered in 2017.
The order is part of the replacement programme of older trailing suction hopper dredgers. The new vessels are a contribution to the further modernisation of Van Oord’s fleet and mark the start of a new generation of trailing suction hopper dredgers. The dredgers will have a length of 158 metres and a width of 36 metres. The vessels will be equipped with two suction pipes with submerged e-driven dredge pumps, two shore discharge dredge pumps, six bottom doors and a total installed power of 23,680 kW. They will have accommodation for 38 persons.
The vessels are to strengthen the company's mid-class section of its hopper fleet. The vessels are characterised by a large deadweight in combination with a shallow draft, which also makes them suitable for coastal protection projects.
Energy Efficiency
During the design phase, special attention was paid to the vessels' energy efficiency. The design includes several aspects which result in substantial reductions in fuel consumption and consequently a fall in CO2 emissions. The vessels are being equipped with innovative and sustainable systems and will obtain a Green Passport and Clean Ship Notation. Van Oord has designed the vessels in-house in cooperation with C-Job Naval Architects.
