Multidisciplinary research vessel
Knud E. Hansen and DTU Aqua (Technical University of Denmark) have completed the comprehensive design study for a new 65m multidisciplinary marine research vessel.
Looking ahead DTU Aqua urgently needs to replace the aging R/V Dana IV as it is facing a 40‐year Class survey in 2022.
The purpose of the project has been to develop a concept design and budgetary costestimate for the replacement of the R/V Dana with scientific capacity and equipment for a highly advanced multidisciplinary research vessel.
The vessel is designed and optimized for cost effective fish stock assessment, hydro‐acoustic studies and biological, chemical and physical oceanography based on DTU Aqua's expected service profile in 2023.
The following objectives have been prioritized:
- Maximum capacity for hydro acoustic scientific performance
- High efficiency in fish stock monitoring
- High scientific multidisciplinary performance through versatile design
- Year‐round operation in North Sea and Baltics
- Summer/ Autumn operation in Greenland and Polar waters
- Low operational costs
The vessel is designed for class notation DNVGL ✠ 1A, SPS, EO, DYNPOS (AUTS), PC (6), and to comply with the ICES CRR 209 standard for low underwater radiated noise (URN) emission. In carrying out the design, the key design drivers and other design issues have been scrutinized and evaluated to arrive at optimal design solutions, which prioritizes regulatory compliance, safety, and environment.
The DTU Aqua operating area will primarily be the Baltic Sea, the Gulf of Bothnia, the Kattegat, the Skagerrak, the North Sea, the North Atlantic and Greenlandic waters in summer and autumn. The vessel is designed to operate world‐wide including the geographical coverage area of the IMO Polar Code up till approx. 80o N depending on the ice situation.
The vessel is arranged with a full suite of hydro‐acoustic transducers, multiple laboratories, trawl gear, cranes, CTD and deck equipment to support multi‐disciplinary research operations. The CTD cranes can operate and sample water to depths of 3000m as well as handle underwater equipment ranging from small plankton nets and bottom corers and towing of multinets. The multifunction deck is equipped with a bolt grid for flexible arrangement of research gear combined with up to four ISO 20' containers.
