A bit of research would narrow down the possibilites. Imperial Navy officers' rank lists and, probably easier to wade though as the navy was considerably smaller, any later Reichsmarine Rangliste are available.
The commission date of April 1 (1.4.) will help as well.
There's also a specific Rangliste von Beamten der Kaiserlich Deutschen Marine f�r das Jahr ..., rank list for navy administration officials as well as Ehrenrangliste der Kaiserlich Deutschen Marine from 1930.
At 25 years, the officer's rank would have be relatively high so, again, the process of elimination should make an identification possible.
Comparing that to the list of Tirpitz officers in 1941 should give you some names, and perhaps only one who would be your man.
The other question might be if the "Verwaltung" refers to the recipient's position or the awarding body. In other words, the dagger may have been presented by the administration of the Tirpitz.
Usually, a presentation is made by an entity or individual so the ship's administration could have given the dagger to the recipient.
There's certain logic to presume that's the case here. If an officer celebrated his 25th jubilee while serving on the Tirpitz, the award would come from its commanding body, the ship's administration.
