This design brief stated the following priorities: maximum draught and possibility to beach (identical to the current vessel), followed by a larger capacity, as efficient and green as possible, and sustainable, with minimum maintenance costs. Late 2018 the concept design-phase really started. This involves going through the regular workflow: speed, maneuvering and seakeeping studies and an outline of the propulsion concept. “In addition, much attention was given to (future) solutions to make the vessel emission free,” adds Rügebregt.
With a length of 37 metres, the RV Wim Wolff will be longer than the RV Navicula (25.5 metres), and unlike the current vessel, it will be produced from aluminum and it will be state-of-the-art, innovative and environmentally friendly. The new vessel is as green as is currently possible, with minimal emissions thanks to the use of HVO (Hydrotreated Vegetable Oil), the most sustainable form available at the moment. In addition, the noise emissions above as well as beneath the water surface are exceptionally low and there are no emissions of waste or sewage water.
“provided the technical part of the tender documents,” Rügebregt concludes. “In practice, this mainly meant drafting the tender specifications, but in such a way that they complied with the European tendering rules and precisely described what the NIOZ wanted. The result is a spec that seems very normal but is very carefully worded.”
