Should Western countries keep sanctioning Russian oil tankers to pressure Moscow's war funding?
Russian shadow fleet oil tankers have begun fitting nets, metal structures, and rubber tyres to guard against Ukrainian drone attacks. At least 60 such tankers have passed through the Bosphorus since August, almost all under US and other Western sanctions for carrying Russian oil.
Why it matters
The retrofits show how drone warfare is pushing commercial shipping to adopt improvised defenses borrowed from military equipment. For operators in shipping, insurance, and energy logistics, the episode signals rising physical-security costs and risk in Black Sea transit.

The details
Tankers are fitting nets, metal structures, and rubber tyres, with tyres hung from the deck around the engine and rudder area. The structures are meant to protect the engines and most vulnerable parts so that a drone strike cannot disable the vessel. Similar metal cages have previously been used by Russian, Ukrainian, and Israeli forces against FPV drones, and Financial Times reporting says shadow fleet tankers in the Black Sea transmit false coordinates to conceal their routes.
Timeline
Since August: tankers began passing the Bosphorus with anti-drone structures fitted.
Market Landscape
Metal structures similar to those used by the Israeli military to counter drones are now appearing on sanctioned Russian shadow fleet tankers. The adaptation shows commercial shipping borrowing military countermeasures as drone attacks on vessels spread.
Operators in shipping, insurance, and energy logistics should factor in higher physical-security and routing costs for vessels transiting the Black Sea and Bosphorus. Sanctions exposure remains a central compliance concern for any counterparty touching these tankers.
The takeaway
Treat vessel security and sanctions screening as linked line items when assessing Black Sea freight risk. Review counterparty and route documentation with qualified sanctions counsel before committing cargo.
