 I looked into it and this is what is known about the 9. Sicherungsdivision (Kriegsmarine) during that period:
 Establishment & Area of Operation: Formed June 17, 1944 ; responsible for the central to eastern Baltic Sea (from the Pomeranian to the Estonian coast). Staff headquarters was initially located in Windau (Ventspils) .
 Commander on August 2, 1944: Konteradmiral Kurt Böhmer (June–October 1944). That fits exactly with the signature “Konteradmiral und Führer der 9. Sicherungsdivision” on your EK2 certificate of 2-8-1944. Wikipedia
 Typical tasks in July 1944: convoy and coastal security, minelaying/minesweeping, and U-boat hunting in the eastern Baltic Sea (Latvian/Estonian waters, Gulf of Finland). The division consisted of, among other things, minesweeping and security flotillas, U-boat hunting flotillas, and landing flotillas. Wikipediawlb-stuttgart.delexikon-der-wehrmacht.de
 Directly subsequent event (August 1944):
 On August 18, 1944, the 6th Torpedo Boat Flotilla (boats T 22, T 30, and T 32) ran into a German minefield in Narwa Bay ; three boats sank. The 9th Security Division then launched a rescue operation in Narwa Bay.
