A former Russian-controlled tanker remains detained in the UK, six years after being hit by a research ship.

The 2,800-dwt Tecoil Polaris (built 1990), since renamed Arves Oil, has been sold twice while being held by UK authorities but appears no nearer to leaving the port of Immingham in England.

The name change was made in September 2022, while Arves Oil of Panama is listed as buying the tanker in March 2023.
