Hi Gentlemen,
the number of the crew in the Control Room (as well as in other rooms) were determined by so called
Rollentafeln. They were divided into two parts:
seemännisch (nautical) and
technisch. Each part described function of the crew member in every condition (that means
Klarmachen zum Tauchen,
Friedens Tauchstation,
Kriegsmarsch,
Freiwache,
Gefechtstation,
Artillerie Gefechtstation,
Boje über Board,
Manöver). In
Kriegsmarsch condition, during dive, in Control Room there are following persons:
- forward dive plane operator
- aft dive plane operator
- vent of ballast tank 5 operator
- negative tanks stb operator
- negative tanks port operator
- vent of ballast tank 3 stb operator (also ballast tanks 2 and 4 stb when used - they were fitted with common vent)
- vent of ballast tank 3 port operator (also ballast tanks 2 and 4 port when used - they were fitted with common vent)
As the ballast tank 1 according to regulations had to be vented as last one, the vent valve could be operated by one of persons mentioned before.
Also there were persons mentioned by Tore - commanding officer (or officer of the watch), chief engineer, torpedo officer.
I believe, that blowing distributor, trim station or pump operator roles were performed by some of persons listed above.
Generally, Tore has interesting experience from the Norwegian service of U-995.
- main rudder operator was in conning tower (rudder station in control room was kind of emergency one. Although Tore said some time ago, that when
KMN Kaura was in service, the common practice was to use control room station, as it was more convenient while snorkeling)
Generally, it seems, that in control room should be much about 10 people. For comparison - on type IXC U-Boats:
When surfaced, there are five persons in the control room. At battle stations, there are ten.
