Interesting photo Stein.

Why are there so many pressure gauges on top of the boilers?

If these are turbines are they multi-stage?
Would they require the watch engineer to know how the pressure was dropping through the turbine?

Just a thought, probably far astern.(Jester)

Frank ;
Those are the turbines ( turbine casings ) not the boilers . The pressure gauges on the top show the pressure at each stage of the turbine .
That should help answere Marconi Sahibs question too .
The pressure drop between stages is a function of the turbine design and is not adjustable by the engineers on watch . However if there is a problem with a row of turbine blades ( either on the rotor or the fixed blades on the casing ); or a problem with the seals beween stages then this would show up and be detected by observation of the recorded pressures taken from the gauges you have remarked upon on the casing top.
The pressure gauges on the turbine front would be gland steam pressure on the forward and aft shaft seals .

Thanks guys,

I have never sailed on a Steam Ship, only been on Motor Ships.

I hear you mate - boring times and I couldn't stand the white gloves! I only did enough time for my ticket, never went back - mind you they converted all out steam ships in to motor ships or scraped em!
