HMS DALRYMPLE was sold to
Portugal and renamed NRP AFONSO DE ALBUQUERQUE in March 1966) This sale may be in
part due to the significant degree of co-operation and liaison between the two
Hydrographic Services. Portugal had also purchased two
other BA Class AA Frigates whose basic machinery was identical. She continued
to be used as a Survey Ship. She was used to carry out
hydrographic work on the Portuguese Continental
Shelf, off the Azores and the Madeira Islands. After being
de-commissioned on 14 January 1983 the ship was used to accommodate ships
companies during refits in the Portuguese Naval Dockyard at Lisbon. In
1988 the Portuguese Naval Attache in London confirmed
she was still used in this role and so must have then have been the last LOCH Class
hull still afloat.
