I have been on the SS Shieldhall ship three times want a fantastic experience you get on how the triple expansion engines work as used in Titanic, although on a on much smaller scale but the principal of steam is the same. The telegraph message from bridge to the engine room telegraph is very much the same as in Titanic to. The only main different is oil been used in the boilers and not coal. The temperature of the oil fired boiler room is over 100f as in Titanic can be as high 120-140f, and back breaking shovelling coal into the boilers. Even the bridge is some thing like on the Titanic again on a smaller scale. All those lovely polished brass work and varnish wood work. The steering gear is very much the same principal as Titanic to.
I would recommend a trip to anybody and the ship is still running to day, but with covid-19 restrictions.
Mike, I'm assuming she's in the UK? Wish I'd known about this when I lived there.

Your Welcome. Glad you liked. If you haven't seen the movie The Sand Pebbles theres some really good engine room scenes in that movie. Although its a smaller engine and different type(still boiler driven) theres still some good stuff in it.

SS Shieldhall is base at Southampton usually at berth 48, two berth away from Titanic set sail at berth 44 which is marked with painted orange bollards. If you seen the video of SS Shieldhall where Queen Mary 2 is leaving berth. Berth 44 is on the other side of the ship. The other interest in Sheildhall she is a rivet built hull not welded. Not bad for a ship built in the 1954!
There is another video of a triple expansion engine at Kempton Steam Museum used at one time for pumping water to London. Which I am a volunteer there. At the present is the worlds largest working steam engine. As used in quite a few Titanic documentaries. However the size of the engine give you a good impression how big this engine were in the past. Although Titanic engines where more than twice the size in cc capacity!

You guys have some good museums there. I was lucky enough to visit a few of them. Glad they are saving some of the older technology so people can see how we got where we are today. I would like that steam museum. I spent hours in the transportation museum in Glasgow, at least I think thats what they called it. The Glenlee was also a cool ship to go thru.

Hi folks, this is the latest progress on my engine build. I've jumped ahead a bit here and moved on to the cylinders, beginning with the Low Pressure Cylinders. It's a 'first pass', so early in their construction and loads still to do. Bearing in mind that it is WIP, feel free to let me know if you see anything wrong.

Latest update on the Low Pressure Cylinder work on the engine...The 'feet/clamps' have been added to the Cylinder allowing it to be fixed to to the Y columns, the openings for the Piston and valve rods have been added as well as the feed Pipes from the Intermediate Cylinder to the LP Cylinder Valve Gear Steam Chest...other piping elements have been added, though but I'm sure there is loads more to do, including the piping from the drain cocks to the steam traps and of course the massive exhaust pipe that carries the expended steam from the LP Cylinders to the Turbine Engine is still to be added. I'm including a very 'rough and ready' low quality rendering of the animation for the LP Cyl elements, because frankly, I really like the 'Red Clay' rendering mode in 3DS Max
1f603.png
. It'll be best watched on loop...As ever, since there are some areas where some assumptions/guesses have had to be made due to lack of info, criticism and correction is welcome.
The Red rectangle visible in some of the images represents the height of an average human relative to the Cylinder...

Hi All, latest update on the engine, The Intermediate Pressure Cylinder under construction, still a work in progress. Crits welcome.

I haven't done this before so I figured it would be interesting to see how they match up. It's an interesting way of finding errors. There are a couple of minor tweaks needed based on putting these two images side by side but happily, nothing major. One thing to note is that the camera in 3DS Max is very different to the one used to take the original Image of Titanic's port engine (photo Credit - Robert John Welch), so the match between the two images is far from precise, with the Welch image seeming to have an almost fish eye lens effect to it. I can probably emulate this in my modelling software, but for now this will do I reckon...Another thing to note is that I don't have a directional light set up in my image, so there are no shadows as such.

Hi folks, latest images of the engine project, this time rendered in Marmoset Toolbag 4. Three of the 4 cylinders are in place - in fact it's essentially what was in the last batch of images but fully rendered...Couldn't resist playing about with these images in Photoshop, so they've been tweaked a bit.

WOW!!!!!!
I can only imagine if you made the Turbine and Electric engines how AWESOME it'd look!

Nice work indeed. Don't forget the 10 holes on the crankshaft in the middle of the flywheels are just holes to bolt the prop shaft onto. Could slightly increase the hole size too. Still great work you are doing.

Yep, deffo, I hope to add the shafting here eventually, so that end will be re-worked, what you see is temporary.

Latest image of progress on the engine build...it's been at an almost total standstill for a while in terms of new stuff due to heavy work commitments. I've been adding detail to the forward LP Cylinder. As ever, basing it off the available plans - in other words primarily Britannic - I can't be sure that it applies to the Titanic. If anything is here that shouldn't be, let me know by all means. I'd rather be accurate and re-do things than leave inaccurate elements in place. So, whats new...? Well, I've added most of the pins/rivets to the cylinder head caps (there's a few more still to add) and also the lifting hooks used to remove it. More significantly though is the large structure at the forward end of the LP exhaust pipe. There are two apertures visible here in photos of the Britannic's engines, one small and one large. Unfortunately there do not seem to be any photos of what attaches to these openings, but according to the plans (again Britannic), these appear to be some kind of throttle or shut-off valve mechanisms. I've modeled them as best as I can make out from the plans, but I'd be reluctant to sign off on them as verified accurate. Again, any guidance would be welcome. Regardless, it's nice to be getting back into construction!
