Here in Holland the fenders also have concrete under water that looks like a upside down funnel, so when a ship hits that, it will bounce off and nothing can happen to the bridge that way.
That was basically the first thing that came to my mind "Didn't the bridge have bumpers around the pillars?" and a quick look at Google maps at the pillar that got hit and nope, it absolutely did not have any.
It did have some, a bit further away. one on each side of the pillars. Unfortunately the ship moved exactly around them. There were none closer to the pillars. However... this was 200,000 tons at 8 knots... I still find it questionably whether any such barriers could have prevented this
@@LeutnantJoker If you're thinking of the same ones I saw, I don't think those were part of the bridge, they look like bumpers that were around power transmission poles.
100,000 tons at 7.5 Knots is not a small force, especially on a point source, the bow of a ship. I'd be rethinking those structures safety just to be sure.
Agreed. Furthermore, the displacements of these ships like the MV Dali weighing 149,000 tons doesn't even take into account the cargo which is often thousands of TEU/FEUs onboard.
@@Einsteinbombthe ship has a maximum displacement of 149 000 tons, this includes the weight of the ship and its maximum cargo load. The ship has a maximum DWT of 117 000 tons which its it maximum cargo capacity. An empty ship weighs therefore 32 000 tons
@@Einsteinbomb it’s a cargo ship. There are normally 3 different measurements for this kind of of ships 1. Gross tonnage and/or Net tonnage which is the internal volume. 2. Deadweight DWT which is the cargo capacity in weight 3. Displacement, how much a fully loaded ship weighs Is essentially a very large steel shell which has large volume and the weight of the steel hull is relatively low compared to how much water it can displace (Displacement) before it reaches max draft
@@blaydCA And how much force is that going to resist before collapsing like a soda can under your foot? That's like saying "I'm safe in my car because I've got a soda can stuck to my front bumper to take the impact". Bulbous bows are not structural they are there to create an out of phase bow wave so the ship slips through the water with less resistance.
The kinetic energy of a fully laden container ship traveling at 8 knots is more than double the energy of an a320 aircraft flying at cruising speed. It’s a powerful force!
@@MichaelHemotoxin AND THAT is why almost the whole bridge collapsed. Besides, if you look at what PROTECTED the Bay Bridges, you will see it is useful regardless of earthquakes. There are barriers that protect the bridge structure. Please use your brain.
Exactly. The fenders on the bay bridges all have the same basic flaw. They are only a few feet above the water line. So the lower part of any hull will crumple and sheer off and the upper part above the height of the fender will go on and smash into the pier and knock it down. This is just a PR stunt.
as it is seen in Baltimore, such a big ship with its forward stretching bow will simply slide over these barriers, and the bow will hit the bridges pillar. so, the impact from the ship is maybe 10 meters above water, but these barriers are estimately only 3 meters high
I think this guy just went way out on a limb. Those fenders are nowhere near adequate to stop a modern day fully loaded container ship, nor do the create enough distance and separation between the bow of a ship and the a main vertical structural support of the bridge above. I think we are going to see that possibly 50% of the long span bridges over major seaways serving major ports in the US need to be re-designed and upgraded with stronger buffers, be it carefully placed clusters of large high mass dolphins, or very large rock islands around the bridge piers as seen in the new Tampa skyway bridge that replaced the one that was hit and collapsed a number of years ago. It's all about mass. No energy absorbing "Fender" system is going to stop ships like this.
It is fantasy to think that those small fenders would stop a 1,000 foot long heavily loaded ship moving at 8 knots (in my estimation and considering the bow overhang) to avoid destroying the pier leading the collapse of the entire suspended span. Probably looking a 15 knots at the Golden Gate and Bay Bridge.
Building a pier strong enough to withstand the inertia of a strike like this would fill the channel. Other harbours require these big ships to be lead out by tugboats fore and aft. This was an accident waiting to happen.
The bridge is kind of old & fragile. Is time to build a much bigger and solid one. Firstly, quickly need to temporarily repair the existing bridge as it affect millions of travellers. At the same time build a much bigger collision proof bridge as modern new container vessel is going to be more than 1500ft long.
I don’t think there’s a way to temporarily repair the Key Bridge in Baltimore. It’s going to be years before a replacement opens. Edit: well, maybe if there were some long term plans for a new bridge then that might speed up the process a bit. But there are no quick fixes here.
@christianvalentin5344 Unfortunately, the Key Bridge never had any proposals for replacement. Recent focus has been on the Bay Bridge (~20 miles south) replacement cos it too is vulnerable and is pushing 70 years old
The biggest mistake they made is dropping the anker, this made the ship turn to the right wich would not happened if they left it float with the Patapsco River, it most likely would missed the pillar and might have ended up hitting Fort Carroll if at all! the stream of the river would have saved the bridge!
No bridge can take a direct hit from a fully loaded cargo ship. The kinetic force is mind boggling. What u need is concrete dolphins surrounding the pylon holding the bridge.
The New East Bay Bridge is not built as designed, all the anchor bolts were of the wrong steel and broke, and the bridge is being held down by a giant steel belt that will fail in a moderate earthquake or a large boat strike.
Whatever it takes to keep our bridges safe................the elected officials need to listen to the Engineers at what they are telling them, and the officials need to ask the Engineers to revisit the preventative measures already set it place.
We don't have all the reasons why this ship lost power. Our government is investigating why the ship went directly into a supporting column. They did stop cars driving over the bridge. However, some maintenance men were on the bridge repairing the platforms and didn't leave in time for reasons unknown. One question remains, most supporting columns like the ones the massive SF Golden Gate bridge columns have contain huge concrete barriers that surround the huge columns that support the bridge. Unfortunately, we are only human and mistakes like this one are a lesson regarding implementing huge barriers that should be surrounding the pillar posts, (see how the SF G Gate bridge protects the collumns from ship collisions). As ships get bigger, barriers surrounding the huge collumns that support bridges need to be strengthened and protected! This is a wake up call! Why the MAGA Reich refuse to fund Our Presidents infrastructure program which INCLUDED THIS TOPIC ABOUT STRENGTHENING BRIDGES, IS ONE BIG DAMN MYSTERY! ARE MAGA REICH PEOPLE AGAINST AMERICA?

Baltimore bridge was head-on ramming speed. Could happen here, though not likely but possible when the ship loses power and it becomes a battering ram 200,000 tons at 8 mph is a stupendous amount of energy to absorb F=ma is a simple plug in formula
The _Cosco Busan_ oil spill occurred at 08:30 PST on 7 November 2007 between San Francisco and Oakland, California, in which 53,569 US gal of IFO-380 heavy fuel oil, sometimes referred to as "bunker fuel", spilled into San Francisco Bay after the container ship _Cosco Busan_ , operated by Fleet Management Limited struck Delta Tower of the San Francisco-Oakland Bay Bridge in thick fog. Investigators found that maritime pilot John Cota was impaired because of his use of prescription pharmaceuticals while piloting the container vessel, which rendered him unable to use the onboard radar and electronic navigation charts correctly. This occurred despite the fact that the Vessel Traffic Service of the United States Coast Guard warned Cota that the vessel was headed for the bridge. Cota was sentenced to 10 months in federal prison for his role in the incident.
Why you guys going to fix the bridge until it was too late so I didn't do go around and check every bridge out. Or wait until we have more problems it's better to pay money to fix the problem before it's bigger like this happen
Many of these fender systems are to shallow. The nose of a large ship would reach over the fenders and strike the support. It’s nice they are reassuring everyone but this smells like bull sh^*.
