Sanctions screeningGREEN — No qualifying matches across OFAC SDN, OpenSanctions, EU FSD, UN Consolidated, UK OFSI for this vessel's identifiers and current name. 1 name-only hit was found and excluded as a name collision — the source record is a company or individual listing rather than a vessel, so it does not designate this hull. It remains listed under `matches` for review. Also screened under SKY LADY, the other name our identity sources hold for this hull. A former name none of them holds is not screened: a hull designated under it, in a source record that carries no IMO, will not be matched here.Source: ArcNautical sanctions screening · as of 2026-10-11
