Research vessel Aranda
Aranda has icebreaking capabilities, allowing it to operate in harsh northern conditions. This is especially useful during the winter months in the Baltic Sea. She is designed for oceanographic, hydrographic, geophysical and geotechnical investigations as well as anchoring and installation of marine research and measurement equipment and ROV operations. Aranda has sailed globally, visiting both Arctic and Antarctic waters.
The main research area of Aranda is the Baltic Sea, and the vessel is managed by the Finnish Environment Institute. Other regular users of the vessel include the Finnish Meteorological Institute and the Natural Resources Institute Finland. Aranda conducts four longer monitoring voyages annually. These monitoring voyages are part of the Baltic Marine Environment Protection Commission (HELCOM) coordinated Baltic Sea monitoring program. Additionally, the Natural Resources Institute Finland annually monitors the development of fish stocks in the Baltic Sea on its own voyage (ICES-Bias)
Aranda can be widely chartered for various marine research and measurement projects. The vessel is equipped with comprehensive and modern hydroacoustic equipment and can operate numerous geophysical and geotechnical devices. The vessel’s dynamic positioning system ensures excellent station-keeping even in demanding conditions. Aranda is also well-suited for the study and monitoring of underwater infrastructure.
