Between January 2020 and April 2026, the Frio Murmansk had at least 305 likely transshipment meetings. Its most frequent partners include Seawind 1, Ilwaco Indian, Nikolay Chepik, Kapitan Efremov, and Aleksandr Belyakov.

Transshipment occurs when fishing vessels offload their catch to a refrigerated carrier that transports it to port, rather than the vessel going itself. Reefers can haul catch from multiple fishing vessels at once, which makes supply chain tracing difficult.
