The British government blacklisted 11 tankers on Thursday as it announced plans for a 44-country European initiative to disrupt the Russian shadow fleet.

The 11 — which include two previously sanctioned by the European Union — feature ships linked to Russian state carrier Sovcomflot and the sanctioned Dubai-based ship manager Radiating World Shipping Services (RWSS).

The tankers include the 159,300-dwt Rocky Runner (built 2005), which moved to new United Arab Emirates-based management after the UK imposed sanctions on RWSS in December.
