The Russia (Sanctions) (EU Exit) (Amendment) (No. 4) Regulations 2022 amend the Russia (Sanctions) (EU Exit) Regulations 2019 AND provide for new shipping sanctions measures in relation to Russia. They prohibit Russian ships, and other ships specified by the Secretary of State, from entering ports in the UK. They also allow the authorities to detain Russian ships or specified ships at ports or anchorages. The registration of ships on the UK Ship Register is prohibited where they are owned, controlled, chartered or operated by a designated person or persons connected with Russia, or where they are a specified ship.
