    'Single point of failure' in the bridge construction. If that pillar goes, everything collapses. That is a build-in disaster scenario. Pillar should have been protected by a buffer zone, but there is none. The ships in the harbor have become bigger by time, thus protection should have been increased as well. That is normal anticipation on changing circumstances.

    Seriously! As someone who has spent several years sailing… there’s something really odd about this whole thing. There are too many “coincidences” or things “going wrong” All the control systems go off? The steering goes out? No tug boats? They throw the anchor out? The ship makes “evasive maneuvers” in the last few minutes… and it strikes? So, if the evasive maneuvers HADN’T been made, it would have missed the bridge supports? AND… within a few hours, the federal government of the USA says they will cover all costs? Right… instead of letting the insurance company do a full investigation before they decide whether they will cover it or not “Nothing to see here!”

    Then maybe it isn't a great idea to have any bridge in the area of a major port if bridge supports aren't designed to withstand hits from a ship. It may not be a daily occurrence but if it does happen, that poses a huge problem. And it's not too far-fetched to think that a ship could possibly hit a bridge. That bridge was 50 years old. The ship was built in 2015. I bet that newer ship was bigger and capable of carrying more cargo, than any ship that was in service in 1972. Even cruise ships are getting bigger.

    The off and on is different backup systems kicking in from main engine systems backups. There are multiple systems for the ship, but ultimately, they are all tied into the same electric distribution. A ship isn't like a car, I could write pages explaining, but any failure in one system can cause catastrophic issues in others, say an electrical fire etc. (Example oil 'pumps' are completely separate systems from the engine).These ships don't have azipods, maybe few thrusters(side to side, dock maneuvers)so that means that getting backup power means nothing. As for the anchors, again you can't just flick a switch, they require crew and power to function too, it doesn't matter if they dropped both, physics and inertia. It takes Miles to slow a fully ladden ship, dropping the port anchor was an attempt to create drag and swing her ass back in to the channel and hope for a minor clip, both anchors you'd just go straight if they didn't catch and hope they catch or she slows. Also the crew probably tried for the other but probably exascaped the anchor locker considering the point of impact.

    @@nelsonhelmutt5076I take it you don’t understand how anchors work. An anchor is not meant to stop a moving vessel. It will slow one down of course just from the drag it creates but it will not drastically or suddenly slow it down given this vessel’s size. The chain on an anchor, more technically the weight of the chain, is what keeps a vessel stationary. They were never intended as failsafes but they are used as failsafes because what other options do you really have? The conditions at the bottom will also have an impact on how the anchor and anchor chain work. And even a properly sized anchor and chain can still not be enough for a vessel even with a little bit of current or a tide shift, which is why a lot of vessels have drag alarms for when they’re sitting on anchor. These guys really had no chance of avoiding this because by the time they knew an impact was imminent, it was too late to do anything about it. The forward momentum on a vessel of this size is astronomical, even at slow speeds. These cargo ships can be at cruising speed, throttle down and coast for 10 miles and still be moving at 3-4knts after 10 miles. Those anchors will hold it in place if it’s already stopped, but trying to immediately stop it is a whole different ball game

In Denmark, we are used to many drunken sailors from east and west passing through our busy waters going in and out of the Baltic Sea. There are therefore sandbars around the pillars so that any ship runs aground before reaching a bridge.

    @fieds1988 You have no idea if the bridge was built just fine. Nor do I of course but the question to ask is this. There must be a safety requirement of some sort that says that such and such bridge should be able to take a hit of such and such force. Like any foundation, you can only put that much force on it. Can I suggest that the safety codes of the1970's, when the bridge was built, did not anticipate the increase in cargo ships weight and therefore that developments in boat sizes/weights overtook the codes, like an earthquake stronger than the maximum expected in the calculations would bring down a building? Never rush to jugement.

    This bridge has had hundreds of thousands of ships of all sizes, including thousands just as large and just as loaded as this behemoth, for the past almost 50 years, and there hasn't been a SINGLE instance of a ship-rams-bridge mishap. Why? Because all other ships are seaworthy, and the master and crew followed all the rules and precautions about sailing under this bridge. It is not practical to install barriers around the supports just to prevent this one incident in 50 years. Besides, installing the barriers would narrow the width of the navigable channel under the bridge, and then the port would have to limit the size of ships which can dock here, one of the busiest and biggest ports in the world.

    The support pillar was critical to holding the bridge up. It was a single point of failure. Therefore it would be crucial to ensure that the likelihood of anything hitting it was minimized. There was no buffer around those supports. No redundancy. The ship was ~100,000 tons and having lost power, it was uncontrolled and drifted with the current. The captain (or local pilot) who was steering the ship tried to put it into reverse, and even dropped an anchor, but the forward momentum was too great. At least the pilot was able to signal a Mayday so that authorities on land were able to close the bridge to traffic just in time (though not for the eight construction workers).

    There is a serious failure of risk analysis here. In Hobart Australia the Tasman bridge was collapsed by an ore carrier. When the bridge was rebuilt much was made of the improved piers supports but when you see photos it is obvious the foundations of the new piers are not much larger than the existing piers and no existing pier foundations were improved . Someone was not prepared to pay the cost of tugs guiding ships past the bridge. The piers have no ship collision protection not for the Baltimore bridge nor the Tasman bridge. Bows of ships extend many meters beyond the ship waterline and easily can smash piers so this accident was simply a question of when, not if.

    There's been ships running into bridges a few times a decade in the last century, the bridge was built fine to carry traffic but there was no guards in place to deflect an errant ship. When they replaced the bridge in Tampa after a ship hit in 1980, they built dolphin[guard)s around its piers, and later built berms around them for more protection.

    The ship goes completely dark for about 10 seconds, total loss of power during the turn next to the bridge. The port anchor was dropped to stop the ship but the anchor dragged. with the engines in full reverse rudder control was lost because of the sudden attempted change of direction. No rudder control in full reverse dragging an anchor, but forward momentum was to much.

    It's a continuous span truss bridge. Truss bridges are used in this application because you can span wider channels with less bridge. Essentially, you don't need as many piers and less reinforcing in the bridge members. The downside to a truss bridge is that it's defined as "frature critical." All members rely on each other for support. There's little redundancy in truss bridges compared to other style bridges. The pier wasn't needed to be heavily reinforced since the truss bridge is lighter than a typical concrete bridge. The continuous span truss bridge was used for this application, but the continuous span truss bridge is the reason it collapsed. I would see it replaced with a cable stay bridge. Dolphins will most likely be placed around the piers. The NTSB investigation may result in a federal law requiring dolphins or other protection around bridge piers.

Without the generators providing 415vac power, there is no navigation or engine control. You couldn’t raise or lower the anchor either. The radios work on 12vdc so would not be affected.

    Then be grateful it was only a small container ship that hit it. What would have happened if it had been hit by a LARGER MODERN container ship, presumably it would have wiped out the entire bridge instead of just half. When you design and build something like that bridge you ASSUME THE WORST, name that something WILL hit it and you design it so that when that happens the damage done is minimal. They obviously ignored that lesson in engineering school (and dad WAS an engineer, he always said you think of the worst that might happen and design with that in mind - look at Sydney Harbour Bridge, that was designed by an engineer (or group of) who KNEW WHAT THEY WERE DOING and they designed it to largely withstand such a collision - but seems the team designing this bridge either didn't listen or ignored that bit of civil and structural engineering wisdom.

    Current running theory on the Baltimore Bridge disaster; Just prior to impact, an increase in exhaust gasses (thick smoke) was observed; indicating a heavy increase in power and engine loading; likely as the ship was put 'hard-astern'. With single propped propulsion, there is always a yaw component to the ship's course, as the prop causes a 'paddle-wheel' effect, which in turn will cause the ship to yaw clockwise if put hard astern... This effect is useful when manoeuvring alongside the dock/wharf. In this instance, going hard-astern likely caused a yaw to port at the stern, with corresponding yaw to starboard at the bow and directly putting the ship on course for the bridge pylon.

HAving one bridge downed by an out of control large ship is poor luck, having another one is verging on negligence.. Lessons will have to be learned, other at risk bridges may have to have strengthening works completed to make them more robust to impacts. So no, not case closed, far from it.
