There were two. I think the other was called the Glomar Challenger. One is bigger than the other. One of the two was in Honolulu Harbor. We went down to see it. it was a strange ship that looked like it had an oil drilling rig in the center. We asked the crew what they were about, and they said they were an oceanographic research vessel, and they were exploring the ocean floor for manganese nodules. We bought their story hook line and sinker. I think we must have seen the smaller of the two ships. because it was not massively large. It was the larger of the two that actually hauled up the submarine. The Soviet diesel-electric submarine K-129 sank in the Pacific Ocean 1,560 miles (2,510 km) NW of Hawaii,[7] on 8 March 1968. The USS Halibut identified the wreck site and the CIA crafted an elaborate and highly secret plan to recover the submarine for intelligence purposes. As K-129 had sunk in very deep water, at a depth of 16,500 feet (3 miles or 5 kilometres), a large ship was required for the recovery operation. Such a vessel would be detected easily by Soviet vessels, which might then interfere with the operation, so an elaborate cover story was developed. The CIA contacted Hughes, who agreed to help.
It's pretty clear that the ballast tanks are filled at the rear, then when a big lift is taken up on the front, that works to balance out the rear ballast.
@@mostlyinterested1016 It's a great solution, since land cranes must always carry the balast, whereas this sea crane can vary the ballast to the load lift.
By far you have the best videos about the bridge. I'm noticing that the coverage is getting less by the day probably because of ratings or something else. For me your videos show exactly what is happening and what I want to see. I have been a working man my entire life until I got the cancer so I know exactly what is going on on those barges and cranes. I am very proud of those real men doing the work and it's wonderful to watch on your videos. Please don't stop until after that pos dali is gone. Thanks again
Same reason all the livestreamers that were down on the southern border have left. Views dropped after the initial wave of publicity. Now coverage is sporadic even though the invasion continues.
The company I worked for here in Baltimore built the water/wave testing model for the Hughs Glomar Explorer. Back then we were told it was an oil exploration ship as they did not want to release the real purpose.
Oh that is cool to know the history. Hughes work still used today, really cool! I wondered how that would work given load would be at front of barge. I thought there was some counterweight too, but maybe that was a different crane? Well prolly should watch more than the first 5 min, here we go lol. Thanks for sharing this!
Wow, that was some incredible precise manoeuvring, Especially when you conside how much inertia something that massive must have. A lot of skill there.
Excellent video, the Douglas sounds like shes running some big locomotive diesels, thanks Andy for catching some of the great sounds of that big tug. Thanks for thinking of the cool details us gear heads love to see and hear. Now us interested tech geeks can research all the cool stuff on both those tugs.❤❤
Thank you for showing the videos of the work being done. It fascinating to see how far they have come. It doesn't look like they are doing a lot from far away, but they are working so diligently.
We Can See The Great Progress These Men Are Making With This Crane! Looks Like The Channel Will Open Sooner Than I Thought. Keep Up The Great Work. We Need This Port Open A.S.A.P! Great Team Work!!! Stay Safe And God Bless!
Honestly,i don't know anything about ships.i am so glad you explained that the barge was purposely filled with water.i am sorry but I'm not a sailor.i just want to learn some basics thanks for sharing it's very helpful to me.
The Corps of Engineers had a barge with a permanently mounted crane built with no counter weight. It was a computer system that added water to various compartments as counter weights. It was given to the Mobile district who we had the diving contract with. No one could figure out how to operate the ballast system so it often had to have another crane assist in heavy lifts or repositioned every lift.
It was built for some district in Florida that refused to take it. The Tuscaloosa office got stuck with it. The Columbus office has a 4100 crawler on their barge that Tuscaloosa borrows when possible.
@@tomlong736 Our Feral government at work. 4100's are nice machines. I own 2 of them, still in the boxes. One is a ringer. Really enjoying this crane show!
The crane operators have to inspect every inch of chains, cable and winches to ensure that none break at the worst possible moment. Kudo's to Operating Engineers!
I remember the CIA cover story was the Glomar Explorer was built to recover manganese nodules from the sea floor. Word was also passed that bodies of the Russian sailors were recovered and given a dignified burial at sea. Thanks for your work, and YOU stay safe out there. Jon
Hi from the uk I was involved in the building of the second seven crossing and we had a massive floating crane called the Lisa A and was used to place the cassons of the bridge each casson weighed the equivalent of ten jumbo jet’s , there is some massive stuff out there ain’t there, great vid though bro
The Chesapeake 1000 (designed back in the early 1970's) has to flood its stern for Ballast from 8' empty to about 16 to 17 feet of DRAFT for heavy picks -- Google LEFT COAST LIFTER -- It is a much newer and much larger crane that helped remove and build the new Tappan Zee bridge bridge. It's currently moored on the East Coast in New Jersey. It's barge is 400' long by 100' wide . It's larger size enables it to NOT have to flood it's stern much for ballast (only a foot or so of internal flooding) -- its draft is 10' empty and only 2' deeper (12' draft) for heavy picks. It picked up Amtrak's entire Spuyton Duyvil Bridge truss in a single pick in 2018.
Hi Andy considering the weight she can lift looks like she could be waiting for a heavier lift serious ballasting, 400+ tone she was level on the water. All cred Andy doing a great job 👍
This is a tiny crane barge compared to wants out there now and in the past. Understanding this may be the biggest in that area and was available when the bridge was hit. The one crane barge similar in appearance that comes to mind is one that use to be in Louisanna. The lifting block was 26ft wide with 72 parts of wrist size cable. The barge was 650ft long and 150ft wide. The boom and back stay folded down onto the barge via rails on the barge deck for transport. I wish I could post a pic here. It also was moved around by tug. The lifting boom was probably 450 to 500 ft long.
Awesome coverage. Wow, tensions must have been high. I couldn't imagine losing that stuff. I've always been fascinated by Howard Hughes. As always Great Content Andy❤
By strict definition this is a Stiff-Leg Derrick. The only means of turning this machine, thus the load, is by the tug rotating the barge. The rear tug pushes forward or backward and the tug on the side does the same, centering the hook over the intended load.
To Minorcan mullet if you find any information on the other 2-people in water thats still missing were asking from are hearts 💕 to tell us please 🙏 your doing fantastic job 👏 keep up great video's 👍
Last time we rode the ferry from Daulphine Island to Fort Morgan, there were several platforms in the Gulf that looked empty. Is that still the case, due to the nursing home resident in chief?
I believe the crane was used in the construction of the Glomar Explorer. It wasn't on the ship. I also believe Hughes was used as a cover story only. Perhaps he provided some funding or his company made money as well. I forgot.
The Glomar explorer was built by Hughes for the CIA to recover a Russian submarine that sank in very deep water. The cover that I saw at the time was that the Glomar explorer was going to do deep ocean mining for manganese modules. The true story was classified for decades.
Thanks Capt Andy!!! That is one BIG tug,,,, I don't ever remember seeing one that big along the GA coast, course I might have missed it easily since I don't live down there. Be safe and Blessed Capt!!!! BTW any word on Capt Johnny???
This is in MD, not GA. But my bet is that the tug and the barge crane are a matched pair. I note that the paint on the tug wheelhouse matches the paint on the structures on the barge with the exception of the crane booms.
Water inside a tank in the hull. A barge is a different kind of creature. I imagine it has ballast compartments. They are probably filled and pumped out from deck plate hatches. Maybe Capt Andy will eventually give us more details on exactly how they manage the ballast.
Interesting view. Makes me wonder if they are going to attach that hydraulic clam shell to the 1000, but I doubt it is equipped with the necessary hydraulic systems.
Sorry, I must have missed the part of how they brought this beautiful piece of equipment up the coast. Did you cover it? Would like to see it if you did.
Yes this crane is big BUT the one I pass every day to work is almost twice as big (Left Coast Lifter) lifts 2000 tons I believe. built Bay Bridge and the TappanZee Bridge. Docked at Caldell Drydock Co.
I TRIED FINDING THE SPECIFICATIONS ON THE CHESEPEAKE 1000 LIKE THE CABLE SIZE FOR THE BOOM AND THE LIFTING CABLES-CAN YOU PUT ME IN THE RIGHT DIRECTION. FASINATINGS THE AMOUNT OF WEIGHT. I RAN A SMALL 25 TON ALL TERRAIN CRANE FOR A SMALL CONSTRUCTION CO. IN OMAHA.
@brendakrivanek9036 About twenty years ago I had the opportunity to look at some of the rigging hardware used by the Chesapeake 1,000. The lifting slings were absolutely massive. Workers would have to have a crane,forklift, or front end loader to move those around.By the way, they were all wire rope slings, not synthetic material.I can recall that the eyes of the big slings were wrapped in what appeared to be polyester material. Basically flat, three inch wide polyester strapping to protect the eye section of the slings from abrasion while on the hook. So yes all the rigging gear for the Chesapeake 1,000 is extremely heavy duty. Take Care.
These Cranes Are Very Well Taken Care Of.The Cable Drums,Dead Ends Chives. The Raps On The Drums Are Must Be Inspeced Often To Insure Their Is No Binding.The Dog Must Be Secure To Make Sure The Boom Is Locked When Making The Crane Safe To Use!!
Does anyone know how much the ballast tanks hold? I did a ‘back of the envelope’ calculation🤓 Now that Ive seen her draught marks, my slide rule will have a better chance of getting close. 👍 The results look something like this: Assuming an even keel and 1000 short tons @ 63’ past the bow; barge would need 3500T of ballast water with a CoG, 50’ aft of midships. This would increase her draft by 6.5’, giving a working draught of about 15’. 🤓 Looking at her marks I would think I’m in the right ballpark. 👍 Hope this helps.
It works similar to a submarine pump water in to sink lower and out to come up , if they are not working the crane and just moving it from one job to another they will pump the water out and make it lighter.
Isn't boyancy and water displacement a wonderful thing... You are doing a great job Andy keep it up. Have you heard from the big crane that cut up and lifted the Golden Ray? Do you know where it is working now? Kinda miss that big ol yellow monstrosity. I can still see you and the Mullet escorting it out to sea talking to the tug captain wishing them fair sailing...
so the glomar explorer was lifting the russian submarine out in the ocean. would this barge crane be able to handle the waves in the ocean?? or was it used to help construct the glomar explorer in port?
there are bigger crane barges coming in mainly for the bridge rebuild but they have even bigger capacities than this one with the ability to slew the crane boom making work faster. most marine construction is down in the gulf and it takes about 20-30 days to tow a barge from the gulf to here. this crane is a baby in the marine lifting industry
When you lift loads that big and heavy, you have to have counter weights. I would say the tank ballast is off and there's a tank ballast pump failure. But that is just an engineers guess
GLOMAR EXPLORER
The Minorcan Navy always is here to keep the information on a true bearing! Yes you are correct!
so right....Project Azorian,
was NOT nuclear sub ,,,did have nuclear weapons

Water counterweight.
@@mostlyinterested1016 It's a great solution, since land cranes must always carry the balast, whereas this sea crane can vary the ballast to the load lift.
Kind of like those thick steel plates on a tractor or forklift. Farmers also fill their traction tires with a water solution.
Samson looks the same when prepped for a lift

In my prayers brother get better God bless you
Water is a free counterweight that is easy to get rid of after the job. Most all ships use ballast to improve trim levels
Even then this site is complicated by debris being stuck in mud and underwater. Chessie's latest lift will have taken over two days since it's so big
I am a land-lubber from Nebraska. This project and your coverage is fascinating
The company I worked for here in Baltimore built the water/wave testing model for the Hughs Glomar Explorer. Back then we were told it was an oil exploration ship as they did not want to release the real purpose.

@@coastaldavhawthorne5891That appears to be a 4,400 ton crane. The Chesapeake is 1,000 tons. The largest appears to be sleapnir at 10,000 tons.

Good stats! Thx for the update!
Wow. That's wild it has that much water in the tanks and is still afloat without weight on the front
I find the amazing part that it is pretty much level when it has a load on the cable.
The CP1000 can accomplish heavy lifts, but it's not easily maneuverable. It's more for getting something really heavy off the bottom.
Filling the ballast in the rear for lifting weight.

Great Content Mr Andy Coming to you from Brunswick GA
If they didn't balast the stern, it would flip onto its bow during a heavy lift.
Interesting view. Makes me wonder if they are going to attach that hydraulic clam shell to the 1000, but I doubt it is equipped with the necessary hydraulic systems.
More importantly, it has no slewing ability. After each grab, you would need to move the crane barge, or bring a hopper barge in, to empty the bucket.
Why does appear the lights on the tug are flashing?
Recording rate. Frames per second.

Is there a guy up in the tower on the barge that runs the crane?
Yes there is!

Sorry, I must have missed the part of how they brought this beautiful piece of equipment up the coast. Did you cover it? Would like to see it if you did.
Why wasn't the ballast emptied for this move?
Probably because they have another lift scheduled today.
It gets the job done. What does it matter if there's a bigger one in Norway or Louisiana🤔
I can almost smell the Diesel smoke.
Yes this crane is big BUT the one I pass every day to work is almost twice as big (Left Coast Lifter) lifts 2000 tons I believe. built Bay Bridge and the TappanZee Bridge. Docked at Caldell Drydock Co.

Does anyone know how much the ballast tanks hold?
I did a ‘back of the envelope’ calculation🤓
Now that Ive seen her draught marks, my slide rule will have a better chance of getting close. 👍
The results look something like this:
Assuming an even keel and 1000 short tons @ 63’ past the bow; barge would need 3500T of ballast water with a CoG, 50’ aft of midships. This would increase her draft by 6.5’, giving a working draught of about 15’. 🤓
Looking at her marks I would think I’m in the right ballpark. 👍
Hope this helps.
How is the crain powerd?
Does it stay on site day and night?
Thank for info.
She's just floating with style.
does the barge have any power on board to side thrust or is all propulsion done by the tug?
Tugs
It works similar to a submarine pump water in to sink lower and out to come up , if they are not working the crane and just moving it from one job to another they will pump the water out and make it lighter.
Do they have some kind of baffling system to hold the water in the stern when heavy lifting?
Excellent...thank you!!!
Isn't boyancy and water displacement a wonderful thing... You are doing a great job Andy keep it up. Have you heard from the big crane that cut up and lifted the Golden Ray? Do you know where it is working now? Kinda miss that big ol yellow monstrosity. I can still see you and the Mullet escorting it out to sea talking to the tug captain wishing them fair sailing...
Perhaps the ballast pump is broken? Unladen moving to dock. Even when loaded she was low in the stern.
I would think when lifting big loads by its crane it is counterbalance which the big load by the crane lifting.
Awesome to watch
I think Hughes Corp. did make a nice chunk but as far as Howard's direct involvement, it is unknown.
The real name should Chesapeake 907, because 1000 short tons equals 907 tonnes (real metric tones).
Ballasting right?
Those Don Jon tugs are museum pieces. How old are these tugs ? They have a early to mid 20th century look :)
That thing's a floating football field!
Has it gone over there to be fitted with that giant grab?
Not yet
does the Chesapeake have it own enging
Looks like a bird faking to be injured to protect its children.
Seems logical explanation for now . If it does sink someone is in big trouble.
so the glomar explorer was lifting the russian submarine out in the ocean. would this barge crane be able to handle the waves in the ocean?? or was it used to help construct the glomar explorer in port?
there are bigger crane barges coming in mainly for the bridge rebuild but they have even bigger capacities than this one with the ability to slew the crane boom making work faster. most marine construction is down in the gulf and it takes about 20-30 days to tow a barge from the gulf to here. this crane is a baby in the marine lifting industry
When you lift loads that big and heavy, you have to have counter weights. I would say the tank ballast is off and there's a tank ballast pump failure. But that is just an engineers guess
They are between lifts and not bothering to unbalast and rebalast is my guess.
