The vessel is designed to carry out comprehensive hydrographic surveys and maintain navigation equipment in the waters of ports and approach channels to ports in the waters of the Northern Sea Route, install and maintain floating aids to navigation and coastal markers, deliver SST and radio navigation equipment to shore facilities for specialists and equipment (Project 5776). It belongs to the russian sanctioned FSUE Hydrographic Enterprise, part of the State Atomic Energy Corporation Rosatom. FSUE Hydrographic Enterprise is the owner and operator of one of the largest dredging fleets in russia, the only organization in russia that creates and provides navigation information for the Northern Sea Route, mainly for large oil and LNG tankers, on the most difficult areas and routes in terms of navigation. Hydrographic Enterprise has provided dredging services for a number of major energy projects in russia, including the Vostok oil project. In May 2023, USA imposed sanctions on four research vessels of the Hydrographic Enterprise, including the "Grigoriy Mikheyev", as part of the restrictions on entities involved in expanding russia's future electricity production and export capabilities in strategic industries.

The vessel is designed to carry out a range of hydrographic and hydrological research in the world's oceans, including the tropics and the Arctic. It is designed as a hydrographic research vessel. Once upgraded, it can carry out geophysical surveys as well as other types of research, such as pipeline surveys, seabed surveys, hydrographic surveys, and engineering, geological or environmental sampling.
