Hi Rancor.
The starboard side is the silent blow-off valve. There are two connections on the port side facing forward. One is the relief and the other is the turbine start.
Many of these connections were speculative as we (I) don't have these parts of the piping details for this area of the room. I had followed the suggestions closely as possible which were made by more experienced folks than myself and this is how I have them arranged.
Starboard blow-off:

Port side relief (Large upper valve) to a main exhaust return and the turbine start connected to a regulated steam supply:

Here is a photo of the area on Britannic:

Thanks Stevefury, I think I understand now. The relief line looks like a way to send the auxiliary returns directly to the main condensers instead of the direct contact heater?

And the turbine start allows the turbine to be turned over without the main engines running? Introducing high pressure steam directly into the exhausts of the main engines?

Thanks!

Wow SteveFury, that's an incredible piece of work. Really get a feel for it
Just started looking into Titanic and found a couple of photos, admittedly Hnr.433, of the recip ER in construction, and the control stand from the test bed.
Yours seems to match spot on

All -
I received a pdf on Britannic today which has a drawing of a main engine showing the reversing gear (clip attached). There are steam valves shown for the IP and LP cylinder starting positions mentioned by Steve in one of his posts above, which I must mention in my "starting doc". I've included a clip but cannot post the whole document as it's too large, but I can email it as required. There are some interesting parts to it such as the "three bridge telegraphs..." - see clip from the pdf, and a lot on the intricate lifeboat arrangements. There are hints to describe various safety measures in the light of "recent accidents", but the Titanic is expressly not referred to, though Olympic gets a mention here and there.

Lord knows just how much I would love to get a hold of those plans for Britannic's engines. I desire them immensely — the only other available plans for them are the ones sourced from a French publication and are therefore in metric, introducing unacceptable rounding errors in the dimensions undoubtedly originally crafted in inches and feet. When it comes to accuracy for a Belfast-built ship, it's British units only!

As it appears @codad1946 and @Stevefury have not been sighted for months, has anybody else on this thread the pdf of the plans, that I may request them as well?

The question now becomes, is there anybody else who has taken such a detailed attempt at modeling the reciprocating engine room, or even the turbine room? To my knowledge both spaces are so poorly detailed in the photographic record that one has to make much conjecture in modeling these spaces.

Hello, sorry I haven't visited more often.
To answer some questions, almost all of the drawings I used for reference are either available on the web or from my main source of a pair of books "Titanic the ship Magnificent".
I used volume 1 a lot as it covers old practices of ship construction used on the Olympic class ships, machinery etc. Web sources like the Britanica and other reasonably reliable places. I also relied on the advice and suggestions from historians, sailors who worked on and engineered the older but more modern steam powered ships.

I was given a few proprietary images which covered plumbing and ventilation plans from the 1930 Olympic refit but all others were found in the public domain.

Some aspects of the images I made are definitely Titanic specific but most are a mixture of all 3 Olympic class ships. A few things (but not many) are educated guesses like the appearance and placement of the main steam board.

It took about a year for me to do the reciprocating engine room and boiler room #1.

I have 3 old computers still rendering 24hrs a day making a HD walkthrough tour of the room on all levels. They've been rendering (more or less) for about a year and about 3/4 done.
I also plan to walk through BR1 from Scotland Road afterwards.

Hoping to have this project rendered and wrapped up mid 2019.

Thanks for the kind words!

Hi this is my first post here and as the last post on this subject was some time ago so hope you all see it. Steve love what you have being doing with the 3D it is really cool and the time it must have taken is quite a commitment i take my hat off to you my friend. I am trying to build a 5% scale model of this engine that will run on steam, already have 3800 hours into this build and i am generating more questions than i have answers to. I am working off the French/metric drawing which is really bad quality but did not realise there was a English dimension version which has more detail and better quality where can i get a copy Help, Help, Help? Please.
Sec you posted a picture of the end/side view of the engine which was really good quality where can i get a copy? This picture has helped me the oil feed pipe connected to the bottom of the cross head had to be able to change length and in your picture you can see the telescopic section clearly however its position below the cross head probably means it was not oil for the cross head but was piped down the connecting rod to the big end bearing and the cross head was supplied from somewhere else? anybody got any ideas ?
Does anybody know where the oil supply was attached to the cross head slide plates? there appears to be a hole at the top of the machined oil grooves but where was the pipe connected to it? picture attached.
Does anybody know where the cooling water connects to the cross head slide plates? the only possible connection point i have found is what looks like a round bolt flange at the bottom of the slide plate (picture attached) however this is where Steve has the lifting beam attached and after looking at hidden detail drawing i am inclined to agree. So where are the water connections?

Steve once again terrific job with the 3D thanks for posting and sorry if this is not really posted in the right place.

Griffonv12, that is some excellent engineering. I like how you've used welded frames to (I'm assuming) to get around the problem of having to cast parts. Either way that's some great work.

For some reason I stopped getting the weekly Titanica stuff, this being the first one for ages. I don't have the engine plans, just a document on the Britannic which is quite informative in some areas. As the Olympic lasted for over 24 years, I am amazed that no one took any photos either in the enginerooms or the boiler rooms! I got some engineroom plans with the auxiliaries noted (the Bruce Beveridge ones are good, but don't label the pumps and auxiliaries in the engineroom) from another Titanica guy, Tom (forgotten surname, but can look it up). I would love to get piping schematics, but they didn't exist in those days. I realised this when I thought back to my early days at sea in the late 60s where us engineer cadets crawled under the plates with our notebooks and traced the lines (wish I'd kept them!). Once the Japanese and later the Koreans started shipbuilding, they produced schematics for all the marine systems in booklet form, with two copies each for the owner and the ship. In Olympic's time, the only drawings were the ones made of the piping layouts, but I've never seen any, though they were available on those earlier ships I mention above. Almost unreadable owing to pipes on top of pipes, and around the size of a bedsheet!
If there's anything I can help with, I will, though as a marine engineer by trade I am no model builder! Wish I could do it, or the 3D that Steve does, which is remarkable to say the least. Let me know if you want the Britannic book and I'll send a copy via email or FB messenger?
I wouldn't mind a copy of the French plans, metric or no...
