Between January 2020 and April 2026, the Frio Shinano had at least 78 likely transshipment meetings. Its most frequent partners include Agnes5, Agnes 3, Cosecha, Lu Peng Yuan Yu 27, and Sureste 707.

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.
