I can't answer the claims/awards question but maybe
www.uboat.net could?
I'm pretty sure that several years ago the Ministry of Defence published a set of books and maps (all in a case) which had details and track charts for all the U-boats "followed" by British Intelligence.
For Adriano: listening stations picked up and recorded traffic BdU and the individual U-boats but this was encrypted, so it was passed to Bletchley Park for decoding (if possible). A lot of information could still be derived from direction-finding (as Bruce says), frequencies and the "fist" of the individual morse operators. Take a look at this:

And, if you can get hold of it: "Very Special Intelligence: The Story of the Admiralty's Operational Intelligence Centre, 1939-1945" by Patrick Beesley. It's very good on the non-Ultra aspects of buidling up the intelligence picture.
