    Baltimore Bridge Down

    In Joe's video, the ship is clearly underway with power 43 seconds before impact. Dolphins (barriers protecting the bridge supports) would have probably prevented this accident. Tug boat assistance through the bridge would probably would have prevented the accident.

     

    Look at the Sunshine Skyway to see what I mean about the dolphins.

     

    I understand about the dolphins, but were/are they designed to stop a ship the size of Dali?

     

    I have doubts about the tugs, I'm not sure there would have been enough time or distance for the tugs to prevent the accident  I also wonder how much the wind and tide may have affected what happened.

    I believe that there will be some new bridge protection requirements proposed in the very near future. Dolphin type protection of the main piers on either side of the shipping channel will probably become a required retrofit. They might even require large ships to have tug assistance through areas with bridges that must be traveled under to get to port. None of it will be cheap and ultimately the taxpayer and/or the consumer will be the one paying for it.

     

    I couldn't find the story again, but it was an engineering professor from some fairly prestigious college that said that ANY bridge would have collapsed when a ship of the size of the Dali hits it. The lowest tonnage of the Dali I've read was 95,000 tons with an upper limit,  fully loaded maybe, of 130,000 tons.  Given the reports of maybe 5 minutes between the ship's loss of power and hitting the bridge, I'm not sure that tug boats would have prevented this.

     

    Some things we might see going forward:

    Ships will only be able to leave inside a certain window when bridge traffic is at a minimum

    Preventing vehicular traffic from being on the bridge while the a ship goes underneath (like the old draw bridges)

    Combinations of winds above a certain speed and the tide means ships will not be allowed to leave

    A hard look at port design and a serious effort to make loading and unloading of these enormous ships take place outside of the bridges.

     

    Expect prices of certain things, including ammo, to go up. 

    Expect shortages of things imported from Europe, Africa and the Middle East.

    It will be weeks, if not months, before all the bridge wreckage is removed from the channel.

    It will be years before the bridge is replaced and it might not be in the same spot.

    Looks like it still had engine power by the smoke coming out of the stack and steered towards the abutment. Hard to tell, but a ship the large probably doesn't steer real well in such a short distance. What a mess to clean up. I imagine the whole shipping channel will be closed for a bit while the bridge is in the bay. Damn

     

    The ship weighs nearly as much as a aircraft carrier, but with a lot less engine power

    Lived down in MD for a couple of years and I have no doubt that I've been on that bridge multiple times.

     

    I'm no structural engineer and I understand ships have gotten much bigger sine the bridge was built,  but shouldn't the designers have taken into account the possibility of a ship hitting one of the foundations or was there just a "domino effect" that caused so many spans to fail and collapse into the river?

    Greyhound with Tom Hanks

    in SASS Wire Saloon

    Posted · Edited by Chantry

    Just finished watching Greyhound with Tom Hanks. 

     

    A good movie with more of an emphasis on action than character development, the special effects are very good and it does a pretty good job of portraying  the challenges of convoy escort.  Definitely worth watching, although I think the movie the Cruel Sea is the best of movies dealing with being an escort ship during WWII.

     

    On edit:  Greyhound was supposed to be released in the theaters in 2020, but Covid prevented that, so it was sold to the  Apple + streaming service.  I'm not sure when it was finally released on DVD.

    The Fletcher class

    in SASS Wire Saloon

    Posted

    The largest class of destroyers ever built, 175 ships launched and generally considered one of the great destroyer designs in history.

     

    "19 Fletchers were lost during World War II; a further 6 more were severely damaged, evaluated as constructive total losses, and not repaired.[1] Postwar, the remainder were decommissioned and put into reserve. Of the 25 Fletchers sunk or deemed as constructive total losses, 17 were lost between March and July 1945 off Okinawa."

     

    One of the very flaws in the design was the single rudder, the Fletcher's had a larger turning circle than the Iowa class battleships.

    NEW 10 for Palerider!

    Ok fellas 22inches was a good call, what says the rogues gallery???

     

     

    The Spanish 10 gauges are way overbuilt.  Mine was cut to 20" when I got it.  When I got home I'm looking at the gun thinking the barrels were less than 18" and uh oh..  I think I measured it 2 or 3 times before I believed the tape measure over my eyes.    Even now every once in a while I forgot just how big the gun is compared to a 12 gauge.

    I wonder what would happen if an actor refused to say those lines

    I don't recall the actresses name, but she was one of the principles on the old show Designing Women.  She was a conservative playing a very liberal character.  She had it in her contract that whenever she had to deliver lines that she strongly disagreed with she would be allowed to sing in the next episode of the show.  I always got a kick out of that and would wonder what she had to say in the previous episode when I saw her singing.

    I cannot post it here or I have a feeling the ban sledgehammer would come out, but if you are not easily offended, have a warped, even dark, sense of humor, and have been in the military (particularly the Army) google "213 Things Skippy is No Longer Allowed to do in the U.S. Army."

    If you are easily offended, do not have a warped, dark sense of humor, DON'T! But it does beg the question, why are you on this thread to begin with?

     

    You've been warned.

    I've read those, very funny, which shows the sense of humor I have.

    7mm or 6.5x55

    as to the 7mm Rem MAG . ain't got much use for one 

     

      the 6,5x55 that I am looking at pretty hard , getting a want for one 

     

     another ctg , that is of interest , is the 6,5x50 Jap , looks to be very efficient

    6.5 x 50 Japanese isn't particularity available or cheap to shoot and as far as I know was never chambered in rifle then the Japanese Type 38 service rifle.

     

    6.5 Creedmoor will do most, if not all, of what the 6.5 x 55 does.  Not trying to toot the horn of the 6.5 Creedmoor, but there seem to be a lot more options for that caliber when it comes to rifles, loaded ammo and components.

    I own a couple of 6.5x55, but haven't shot them in a while.  I am a big fan of the 6.5X55 for accuracy, mild recoil and good ballistics.  The 6.5 Creedmoor comes close to duplicating the 6.5x55 in a shorter (.308 length) action at slightly higher pressures.
