    As you may be able to see if you bother to read the thread from the beginning, this thread does interest me. I occasionally comment on aspects of engineering or things I don’t agree with, as so, it would appear, do you. Cheers Darius

    Especially the examples of narrowboat handling compared to that of the container ship ‘cause they’re essentially the same, right? Cheers Darius

    For some passengers that may not be a positive outcome… Cheers Darius

    Tuned in to get the latest thoughts on the bridge and instead get:- - hatred of the BBC - hatred of journalism - a brief history of friendly fire Time for a thread lock I think until the big crane starts its act. Darius

    Do they fit inside the tunnels this time? Cheers Darius

    Concrete dolphin protection to the piers of the first Forth Road Bridge. They don’t need to absorb all the energy of a ship impact as some of it goes into buckling the ship’s hull and some in deflecting it’s trajectory. Darius

    200 tons of TNT detonating does impart the energy a bit faster than a ship impact. The key parameter is the “impulse” which essentially is how quickly the energy is imparted into whatever is receiving it. For example, I could give you a push on the arm or a punch. Both impart the same energy but the push is slower and the punch much faster. The punch hurts… Darius

    Actually a stretch of the ramps also collapsed. Graphic courtesy of today’s Guardian. Darius

    The concrete pier of the Baltimore bridge was the part struck by the ship and it collapsed causing loss of support to the steel bridge structure and its subsequent progressive collapse. In the still from the NTSB footage below you can see parts of the collapsed reinforced concrete pier structure to one side and actually on top of the bow of the ship. Darius

    The Dartford Crossing (QE2) bridge piers look to have substantial protection. They are also close to the river bank so may be in shallower water than the main navigable channel. Cheers Darius

    I know you are joking but even RB wouldn’t want a driver that would most likely stuff the car into a wall during practice/quali/the race. Cheers Darius

    Easier to do that with a new build than a retrofit. The main protection for the Sunshine Skyway Bridge appears to be a series of massive concrete dolphins marking the main channel. I suspect the replacement for the Francis Scott Key bridge, if and when it is constructed, will have similar protection to the main piers. Darius

    Close up of bridge pier showing the treatment at the water level. I doubt that it would be practicable to install fenders (as such barriers are called) that were independent of the bridge piers, so as to stop the impact load being transferred directly to the pier, in 50’ of water that were capable of absorbing the immense kinetic energy of a ship like that striking them.

    A ver pleasant day out from Worthing yesterday. Train to Bournemouth and the No.50 bus to Swanage. Superb lunch in the Bankes Arms in Corfe Castle 😀 Cheers Darius

    Especially if you want to put Russian donor friends in the House of Lords… Alas funds need to be sought from different sorts of people now… Cheers Darius

    Presumably his Dad and Dad’s money are still banned so no team is likely to give him a drive if no money comes with it. Darius

    EU ban on Mazepin overturned Mazepin to Mercedes in 2025? Probably not… Cheers Darius

    It’s time for a Winston Churchill quote: “A fanatic is one who can't change his mind and won't change the subject.” Cheers Darius

    If you want absolution, I think you are on the wrong forum - and you can quote me on that. Cheers Darius

    Cue sound of crickets chirping. Cheers Darius

    No rucksack no bag search just walk in… It’s a discourage-rucksack measure. Cheers Darius
