- The video depicts a triple expansion steam engine in operation on the Liberty ship Jeremiah O'Brien in San Francisco. The scenes have been taken during March 2019.
Liberty ships were a class of cargo ships built in the United States during World War II in large numbers. The Ships were propelled with a 140-ton vertical triple expansion compound steam engine. The engine's design was obsolete, but the engines were easy to build in high numbers by the many shipyards engaged in the construction of the Liberty ships. The engines were rugged, simple and easy to maintain. The engines are 21 feet (6.4 m) long and 19 feet (5.8 m) tall. It operated at 76 rpm and could propel a Liberty ship at about 11 knots.
The Liberty ship Jeremiah O'Brien is one of a few ships still existing still in operating conditions. It is based in San Francisco.
Very nice job. I am an engineer on the O’Brien now and just came back from a week’s worth of maintenance work. I am the one at 6:04 of the video; the other crew person is Oscill Maloney who is very capable in her duties on here. I have worked in ship’s engine rooms much of my life. I retired from Chevron after a career on their oil tankers and was a Boilerman Third class in the United States Coast Guard before that. Thanks for posting these good shots of the engine room.
Thanks to your colleagues and you to maintain and operate this great ship and steam engine. Highly appreciated. Enjoyed my visit on the ship tremendously, especially since the steam engine was operating!
@@louisfavre04 You are welcome. 👍
Do people sleep/live on the ship me and my girlfriend noticed the old spice in the shower room and all the newer sleeping bags and other things in the old cabin rooms
What are those wooden racks between the frame and crossheads for ?
@@bluegrip3007 Sorry for the delay in getting back to you. Yes, there is always somebody aboard, usually 2 or 3 of us. Some don’t want to commute to far away places, like me, so it’s much nicer to stay aboard. There are the showers, laundry, all the food we need. Some have a room assigned, some just pick an empty bunk for a few nights. Usually the rooms are pretty ush assigned. Thanks for coming aboard.
Love seeing machines like this operating, almost like they are a living breathing thing with a soul and personality.
And I swear I can smell that engine room through the monitor, iron and oil is such a wonderful combination.
My father was a shipfitter aboard the Roberrt Callan, one of these ships during WW2. They were in the great typhoon that got Halsey repremanded. because of all the ships and lives lost. They didn't have our recent weather forecasting technology back then, and had to play it by gut. Dad loved his ship, but endured such terror during that typhoon that he never forgot it. I am so thankful that the people who built that ship did such a good job. It didn't break up like some did. I also commend the Captain and officers that commanded her during this horrific event. They circled the world, making several trips thru the Pacific and Indian Oceans as well as the Atlantic during their cruise. Thanks to the people restoring this ship as a representative of this class of warship, and the ones who made this documentary. Sincerely, FJO, jr.
What a great story Frank & thank you for sharing.
My father was a Navy gunner on Liberty’s and he was extremely pissed about the way his shipmates were treated post war. They were denied GI benefits because they were merchant mariners. He felt that since they were literally in the same boat as he was and facing the same enemy with the same torpedos, they should have gotten the same benefits that he did.
Admiral Thos. J. Patterson who was critical to the saving and restoration of the 0. Brien-went to bat for your Dad's absolute and legitimate claim. Many of the Mariners spoke up and finally succeeded in having recognition and recompense for the brave Merchant Seaman - Make sure to visit the Memorial @ The north end of Golden Gate Bridge!!!
My great grandfather was a gunner on a liberty ship as well. He ran the 4” deck gun.
If I recall correctly, Astoria *also* has such a memorial to merchant seamen. It’s fairly large.
I saw it last October, and took a number of pictures.
i toured this ship years ago and was proud to see the plaque on the side of the massive engine said Made in Hamilton Ohio, not far from where I live. The town used to be a manufacturing powerhouse, but most heavy industry has disappeared. I recently toured a Victory ship in Tampa, the main difference being they used steam turbine engines with three times the HP.
Quietest engine room yet! This gearhead loves to watch, AUGH AUGH!
God bless the sailors and merchant men of the US Navy and Royal Navy. We owe you so much.
I’ve been in the engine room in person with it running. It’s pretty warm during operation and the room is filled with the smell of oil
Thanks for the History... Too often today people just post the picture - no information. So, I'm glad this opened up to some good information.
My Father was ship's electrician on Liberty ships. He said that if you tied the governor down, you could have enough speed to just elude torpedoes.
Also, he added a plunger assembly and a large bucket to one of the connecting rods to do his laundry
Triple expansion marine engine with a governor? Are you sure?
At 19, my dad crewed the forward port 20mm mount on the Helena Majeska
I think it's cool how even though the motor makes alot of noise many of those huge moving parts move so silently
All ahead full!
All ahead full!
Come on lads, step lively!
@@michaelmurray11189Didn’t you guys mention the Cameron’s Titanic, eh?😏
@@insertyournamehere4328 We sure did. 😉
Remember, they built these ships on an Assembly Line! With no CAD! Or cell phones! "Don't get your hands caught in the moving parts!"
Nice shot of the 4” gun. My great grandfather ran one of those on a liberty ship in WWII. He trained to pull off the tarp and unload into an enemy as quick as possible. Unfortunately he died at sea from homemade alcohol poisoning.
this engine was use for the Titanic movie :D ahah
👍😊
Yes absolutely
Thanks... I remember reading in a book on Cameron written by some lady about him using a Liberty Ship. *So, this is the one!*
Really...?

2:35. What is the function of these rather frail-looking pantograph linkages?
Does this engine have a species of “bell” sounding when it begins running? Most “recordings” of the Titanic’s engines have a “bell” sound at the beginning of the clip, and supposedly, *this* engine had a big part in making the audible *and* visual parts.
Note: when the O’Brien berthed in Portland some years back, I was able to get on and look the ship over. The best part was - *of course* - the engine room!
It's mesmerizing
Me watching steam engines at 03:00 in the morning
Oh boy, 3 AM!
Fantastic!
C'est tellement complexe, qu'on se demande comment l'homme arrive à créer cela
At 3:35 there is some massive part of the engine, perhaps attached to the piston rod moving up and down. There are a couple of curved tubes with what look like condoms that are touched when the structure hits the high point in its movement. Are the tubes and "condoms" part of an oiling system?
Yes
What are those wooden pantograph's at 2:49 for ? - They surely are no part of the original engine...
Part of the engine indicating system. Basically the old school way to get data on each cylinders horsepower, pressure, etc used to tune the engine. They will be removed during normal ops.
Thats massive
Does this ship still sail?
Yes.
They usually do air show excursions during San Francisco fleet week
What's the expanding orange thing connected to the for
cool
Belo navio, antiquado mas de comfiança.
I don't see that throwing a rod in my lifetime.
0:38 Wall-e music?
And how did they desalt the water for the boilers ?
There is a fresh water distiller. Basically boil seawater, collect the freshwater vapor and condense it to liquid. The salt collects in the boiling water forming a brine which is occasionally blown down to the sea.
Carried FW for feed. Don't know if liberties had a make up evap. The salt water evap would make a few ton from ocean
Distillers on Merchant Ships really came in post WWII. The salt water evap were next to useless. We would have to take water almost every place we went.
I guess if they have to do an Oil Change, they just have a tanker truck drive up to the pier......
Steam Recips do not have an oil sump. No changes. Someone needs to start a Marine Engineering Course.
On turbine ships and Diesels, Purifiers continually process the lube oil. No changes unless catastrophe. Sometimes Additives.
FULL A STERN!
Hard Over!
That engine's exclusive purpose is to operate the Chompers!

Seriously, who came here after watching Titanic :)
No one?
I was onboard her an an Asian lady read the warning sign saying you are responsible for your own actions and injuries and she said oh no I’m not responsible for my self she was just trying to sue the ship so awful and disgusting
All this space should be used to house the homeless and drug addicted. How can they justify the cost of maintaining this ship if not used for the homeless?
🤦♂️
they would wreck the ship, the ship is tooo beautiful to have them in there, and its a museums ship. i understand some of the homeless people would look after their space, but the druggies and others will wreck the ship, if you want a space for the homeless BUY THEM A HOUSE, DONT PUT THEM IN A SHIP
I was being sarcastic... The homeless need drug treatment in a mental hospital not houses - or ships. @@maddseagull8161
