The ship acted as part of the Fishery Protection Squadron in the North Sea for several years, but was eventually replaced when enough Island-class patrol vessels were available.[2] After a £1.6 million refit at Chatham in 1976, she was assigned to HMS Neptune as a submarine tender, target ship and tug.[1][2]

She was replaced by HMS Sentinel, and decommissioned on 30 October 1987. She was sold to the Greek firm Hellenic Salvage Tugboats in June 1988, having sailed from Portsmouth for Greece the previous month, on 6 May 1988.[2]
