Replacement RV Pelagia

Construction RV Anna Weber-van Bosse

In November 2022, the NWO-I Foundation Board approved the definitive grant of the contract for the construction of RV Anna Weber-van Bosse to Spanish shipbuilder Astilleros Armon. After years of preparations, construction can now begin on this innovative, sustainable and unique vessel that will replace the 35-year-old RV Pelagia. This will be the largest new vessel in the national research fleet, and will be available in two years to all of the Netherlands’ marine researchers. The fleet consists of three vessels managed by the National Marine Facilities (NMF) department of the NIOZ, which is part of the Netherlands Organisation for Scientific Research (NWO).

The flagship of the Dutch research fleet will be named after Anna Weber-van Bosse, the Netherlands’ first female marine biologist to conduct research at sea. Read more in her biography. Here you can read about the event for the start of the construction on 11 October 2023 in Vigo.

RV Anna Weber-van Bosse will be delivered in 2025 at the earliest. You can follow the construction via the timeline below, by subscribing to the newsletter (at the bottom of the linked page) or via social media @ResearchFleetNL.
