Science Tender to RSV Nuyina

A dedicated science tender adds an additional research capability that works independently or together with the Nuyina’s scientific systems.

The vessel has its own state-of-the-art equipment for marine and geoscience work in open water and ice. This includes a sound velocity profiler for oceanographic work and moon pool for the deployment of instruments through the hull. It has a multibeam bathymetric echo sounder to map the sea floor, including in shallow uncharted areas where it could be dangerous to sail Nuyina.

The tender can also tow scientific equipment and small trawl nets, and its small crane (known as a side davit) can launch scientific instruments over the side.

The 10.3 metre-long, 3.5 metre-wide vessel even has a few modern conveniences, including a heater, defroster, sink and toilet. It is operated by two crew and accommodates up to six personnel and 500 kilograms of cargo.
