Адмиралтейские верфи
This civilian college merged in 1826 with the equivalent navy college into the Academy of Navy Engineers. The training academy in St. Petersburg still exists under the name of Higher Academy for Marine Engineers (Военно-морского инженерного училища). In 1829 Berkov returned to the City Wharfs as Director. As such he participated in the merging in 1841-43 of the civilian City Wharfs with the adjacent Navy Admiralty Shipyard into the New Admiralty Shipyard, of which he became Director. He continued this position until his death in 1870. In the hierarchy of the Russian social class system, Berkov rose to the civilian rank of Acting State Councilor (4th class), which equals the rank of Counter-Admiral in the Navy. Whether Berkov had actually held a Navy Admiral rank is subject of debate among Dutch historians.
