Jeff Ostoff shows you the latest videos and photos released today by the US Army Core of Engineers showing the steps they go through to process the Francis Scott Key bridge collapse debris and trusses. Highlights include moving another large section of the collapsed Francis Scott Key Bridge truss, and removing containers from the MV Dali ship, as well as moving the bridge truss over to Sparrows Point in the Baltimore harbor.

They barge the collapsed bridge debris to the new 10-acre laydown yard used by the U.S. Army Corps of Engineers to process wreckage from the Francis Scott Key Bridge site. An estimated 50,000 tons of concrete and steel collapsed; once removed, the wreckage is sorted and transported two miles away by barge to Sparrows Point. Debris and wreckage removal is ongoing in support of a top priority to safely and efficiently open the Fort McHenry channel.

From a retired bridge construction/deconstruction guy - well done. I don't even bother with anybody else's YT's on this subject. I could tell many a story about removing old bridges and working with failed structures, including Galloping Gerty's remains in Tacoma, but that's for later. Note that the 1000 crane, when loaded with the various sections, is still sitting stern down, indicating that the buoyancy unused forward still allows for a great deal more lift.

Jeff: In 1977 when the FSK Bridge was built the shipping channel was 35 feet deep and 500 feet wide. The support pillars were 100 feet outside each side of the channel in 15-20 feet of water. There were modest “dolphins” protecting the bridge from Tug Boats and other smaller Harbor vessels, etc. There was no need to build robust protection because the deep draft ships could not possibly physically strike the supports in the much shallower waters. Then over the years, as I sailed those waters in a Catalina 27, they incrementally deepened and widened the shipping channel to the current 50 deep and 700 feet wide: right NEXT to the supporting pillars. The Corp of Engineers ran the dredging. The MDOT runs the bridge. BUT NOBODY though to REINFORCE or INCREASE the PROTECTION around the SUPPORTS OPPS!🥸 Respectfully Submitted by: Sam Collins Towson, MD

Jeff, thank you for your dedication to presenting current events with a scientific understanding. While you are not a marine architect, you are an engineer that understands the laws of physics. Yesterday, I was watching the live feed and noticed something interesting, the curvature of the earth and waters. I was looking at the barges and saw that the tires used as bumpers were below "the water line" of the vessels. I realized that what I was seeing was the horizon, as the cameras must have been miles away. With your knowledge can you compute the distance and hence how much was occluded? I believe at one mile, the curvature of the earth is more than five feet. Thank you.

The talk about the size of the cranes and the skill of the crane driver is all very well but the real skill and courage in these big lifts on this project lies with the riggers who have the dangerous job of setting up the slings etc. for the lifts. They don't seem to have featured in the video coverage. Good overview of the work though, Jeff. CVB. - Retired Civil Engineer, Cornwall UK

@williamhall9204 Ай бұрын

@colinburrough5621 Excellent point you make. I completely agree with you about the skill and courage of the riggers. I’d like to add that if a rig like the Chesapeake 1000 is using wire rope slings as opposed to synthetic slings, then the work is even harder for the riggers. And of course any heavy lift/ rigging operation is always much more difficult when working on the water.Take Care.

Just a word about a 1000 ton crane load capacity. A crane or hoist labelled 1000 ton capacity will lift 1000 tons safely and efficiently, because there is considerable safety factor applied to that load capacity. I don't know about the USA, but in Canada the Factor of Safety for a material hoist is 5. For personnel hoists it is 10. What remains to be considered is the service life of the crane. Consider 2 cranes of similar load capacity of say 200 tons. One is installed in a power house for servicing and repair of turbines and generators. The other is installed in a steel mill. The first one will see a full capacity load only a few times during its life. The steel mill service will see capacity loads almost every day. These differences are addressed in sizing the brakes and hoisting rope sheaves to get reasonable service life from the brake shoes and hoisting cable. The manufacturer may make other adjustments in design with the agreement of the client. Apart from that each crane will safely lift a full capacity load any time.

Can you imagine working on cutting the beams underwater with no visibility? I would think that process has to be insane as you can't see the hazards, fish, or your cutting torch. I assume they are using an arc method to cut underwater. When visibility is inches, this makes this process 20 times more difficult. The management team is a doing a great job to plan out the tasks and keep everyone working! That means the management team is older, trained, and experienced. Many times, we have to wait for an engineer to develop gray hair before they are experienced enough for large projects.

The 1000 ton lifting capability is at 63 feet of reach. The capacity decreases with longer reaches. We don't know either how good the weight estimate was or the reach. The other consideration is the stability of the piece left behind. Unplanned movement can be very dangerous.

@DB-thats-me Ай бұрын

I was about to make a similar comment. At a relatively light lift at 450T would allow it to luff out some. The hook has to be to out a little over half the width of the load. (Assuming a load width greater than 126’). This crane barge has no slewing ability (with good reason) and so would need some space ‘over the fenders’ to safely land a wide load.

@anamariasherwin1020 Ай бұрын

I would have thought the crane would have an LMI (Load Moment Indicator) so that at all times the operator(s) knew EXACTLY how much weight (load & rigging) was hanging on the hook. With a max pick rating of 1000T @ 63' radius the lifting capacity will probably be about half that at double the radius (125'). So 450 tons was likely to be getting somewhere close to the limit.

@DB-thats-me Ай бұрын

@@anamariasherwin1020 you can take to the bank they know, to the ton, what the max load vs luff angle is. I would love to see the load diagram for this beast. Floating cranes can be a little counterintuitive with regard to what they can lift as opposed to their land-based brothers. I’m not even going to hazard a guess what they are.

Great point on the engineering limits. Even if the C1000 has a theoretical limit of 1000T, it’s important to remember the pieces are stuck in the bottom and the mud. So the suction force and initial lifting forces are larger than the weight of the piece after it’s lifted. So they have to leave some headroom in the lifts for that as well.

That approach has been brought up numerous times on this channel and every other one discussing this incident. The problem with a tunnel is that oversize and hazmat shipments are _prohibited_ from traveling thru them. Now, if the city/state _want_ those shipments to remain on the current surface-road detour around the harbor and Baltimore itself in perpetuity, they may opt for a tunnel. But in all likelihood a bridge (probably a cable-stayed one with a wide span and high deck) will be much cheaper and faster to build.
