In March 1967, at the start of her final commission, "Barrosa" was used in attempts to break up the oil spill from the supertanker "Torrey Canyon", which had run aground off Cornwall, with detergent. In November 1967, she formed part of a naval task force deployed to cover the British Withdrawal from Aden. Other duties during this last commission included taking part in the Beira Patrol. On 2 October 1968, "Barrosa" took the Royal Fleet Auxiliary stores ship "Lyness" in tow after "Lyness" engine had broken down east of Shetland, stopping the supply ship from being driven onto rocks until power could be restored.
