The seizure of a Russian-linked oil tanker in the North Atlantic has highlighted “worry” among NATO and Nordic-Baltic governments over dark fleet vessels and the type of crews onboard, according to a maritime intelligence analyst. U.S. military and Coast Guard personnel boarded the Marinera between Iceland and the U.K. Wednesday as it operated under deceptive shipping practices, including flying a false flag and violating sanctions.
According to Reuters, Russian authorities demanded the humane treatment and repatriation of the crew members. Windward maritime intelligence analyst Michelle Wiese Bockmann claimed the Marinera’s ownership had just been transferred to Burevestmarin LLC, a Russian company.
