 By this time the ship was in poor shape and required an extensive refit ; the work last from 12 November to 17 May 1944 at the North Woolwich , London shipyard of Harland and Wolff . After working up , she was assigned to the 14th Escort Group for anti @-@ submarine operations in the Western Approaches . Duncan conducted convoy escort and anti @-@ submarine operations with the group through April 1945 when she was assigned to the Greenock Coastal Escort Pool . The ship was placed in reserve on 13 May and was transferred to Barrow on 9 June . She approved for immediate disposal on 8 July as she was leaking five tons of water a day . Duncan was turned over to BISCO for scrapping immediately afterwards , but demolition was not completed until 1949 .
