Tores mailbox VIIC and VIIC/41 operation and technical details

[tore]

Warm washwater.
I honestly don`t remember. I assume the horizontal waterpump port fwd engineroom which is connected up to the system, see previous discussion June 5th 2012, was installed after my time. The warm water heater on the aft bulkhead  in the fwd. torpedoroom next to the officers bathroom was definitely installed after my time.

Batteries.
All the batteries were changed and new batteries were made by the Norwegian submarine battery manufacturer. As a part of my education I even took part in the "production" making my own car battery.

Tore, how the floor look like in the galley now?

Simon.
It looks fine to me. A small detail, the small accesshatch close to the range has a larger oval hole. It looks to me that you can see the top of a sounding stick through the hole.  In that case it would be the sounding for the freshwatertank.

Tore, how did the waste water get off the boat? Was it through the bilges then out to sea?

Simon.
Wastewater drain.
The wastewater tank has a connection to the bilgewaterpump in the controlroom as seen on the sketch below.

Further to my last post. As you see  on the sketch I believe it is a washbasin  in the crews WC as well.

Maciek.
The head tank or may better buffertank is not a big tank,just big enough to keep a positive head in the system. It is fed from the coolingwater outlet at the exhaustsilencer, the location is about where I put the arrow on the drawing below.

Simon and Maciek.
I remember you had a question about the watercompensating tank for the fueltanks back in November last year. When looking through my drawingfiles today I came over a GA drawing of the VIIC/41 showing the 1944/45 execution. You are able to see the small tank located in towercasing on the sketch below.

Great found Tore!

Tore, the arrow coming out of the watercompensating tank is a drain?

[NZSnowman]

Tore, I imagine late war water compensating tanks would be were galvanized?

[tore]

Simon.
It could very well be galvanized.

The non coloured arrow probably indicate an outbord drain, not overflow.
Tore

[NZSnowman]

Tore, would the water level be over both pipes?

How does it looks so far?

Will add the piping under the water compensating tank next summer
