Russian Oil Tanker Forwarder Enters English Channel After Smyrtos Boarding
The Russian-flagged tanker, Forwarder, which departed Primorsk last week, entered the English Channel on Wednesday evening, sailing south with its stated destination as Dongying port in China. This movement represents the first instance of a UK-sanctioned "shadow fleet" vessel transiting the Channel since British forces intercepted the Smyrtos early on Sunday morning.
Following the operation against the Smyrtos, ship-tracking data indicated that a number of sanctioned vessels subsequently altered their courses to bypass the waterway. A Royal Navy warship, HMS Tyne, appears to have been operating in the vicinity of the Forwarder's location.
The Forwarder was sanctioned by the UK, US, and EU in 2025. Since the British government accused it of illicitly transporting Russian oil, the vessel has undergone two name changes. Satellite imagery confirms the Forwarder loaded oil at Primorsk, the largest refinery in the Baltic Sea and a critical export hub for Russia's energy sector, before its departure on 12 June.
These "shadow fleet" tankers are crucial to the Kremlin's energy exports, particularly since Western sanctions were imposed in the wake of the 2022 invasion of Ukraine. According to the Ministry of Defence, this clandestine fleet, comprising over 700 ageing vessels with often obscured ownership, transports 75% of Russia's sanctioned oil.
Previous reports from NATO officials indicated that the Russian warship, Admiral Grigorovich, has been assigned to escort sanctioned oil tankers. The Admiral Grigorovich was recently involved in an incident on Tuesday, firing warning shots at a British yacht in the Channel. It remains unconfirmed whether this frigate is accompanying the Forwarder.
In March, Prime Minister Sir Keir Starmer announced that British armed forces were authorised to board sanctioned vessels not complying with international law within UK waters. However, maritime analysts suggest that intercepting the Forwarder, a Russian-flagged vessel potentially under military escort, would constitute a significant escalation beyond previous actions.
The boarding of the Smyrtos, by contrast, had a clearer legal basis, as the vessel was sailing without a registered flag, violating international law. The Smyrtos is currently detained off Weymouth, and its captain faces charges of sanctions contravention. Analysts note that the Forwarder's Russian flag, despite opaque ownership, does not currently provide similar grounds for interception.
