Windward reports that 98 tankers reflagged to Russia in 2025–2026, lifting its total above 213—versus Cameroon’s 157 and Sierra Leone’s 98—among more than 1,000 Western-sanctioned tankers.
Source note: The exact flag counts are single-sourced to Windward. Independent estimates put Russia’s specialized oil fleet above 1,000 vessels and the broader global dark fleet above 1,300 by 2026, but these are differently defined populations and are not directly comparable.
In April 2022, roughly 90–92 Sovcomflot tankers and LNG carriers moved to Dubai-registered SCF Ship Management, later renamed Sun Ship Management. After EU sanctions on Sun, 45 tankers began shifting in July 2023 to Oil Tankers SCF MGMT FZCO.
Sovcomflot first denied the Sun connection, then acknowledged it had been a group company, saying the added restrictions “did not add much.” K&O Ship Management, Fornax and Stream further illustrate the UAE web: continuity of control through Dubai, not an independent foreign substitute.
The EU added 189 vessels in May 2025, taking its listed total to 342—yet the source says more than half the known dark fleet remained untouched. That is a coverage gap, not an argument against vessel sanctions.
Policy must also target RNRC’s state-backed reinsurance, RMRS’s classification authority, the Russian flag registry and Zvezda’s build capacity. These are harder to replace overnight than a vessel manager or convenience flag. Several exact fleet and capacity figures remain single-sourced.
