    Not quite as much as what was asked by the looks.
    There are only three types of people in this world. Those that can count, and those that can't!

    I would suspect the bollard pull was rated at or better than "a lot" most likey closer to "f#$ken heaps"

    Oops

    3 ton anchor?
    Dragged on a bulky Id guess

    We put down the biggest anchors in the Southern Hemisphere last year.
    8x35 ton
    450tons bollard for 30mins had them 15-30 meters into the sea bed.
    800m of chain at 250kg/m

    They are REALLY hard to get out when they pull outside the aray window and you have to reset them

    Think I have a couple of pics if anyone's interested.

    How does this work? Dig a hole or just the weight of them? Or the design that when dragged they dig themselves in that deep?

    They dig themselves in.
    The fluke angle is adjustable and by the time you have 800m of chain out and the other boat connected to the bow (it pulls 200t on us) they have to bed and set within a certain distance - a box as such.
    If they slip of finish bedded outside the box you spend 12 hrs pulling it out. They usually come out ok if they are tipped over backwards to break fluke purchase.
    Brought back up, fluke angle changed and repeat the process.

    Get to do some interesting work.
    In last year worlds biggest pipe layer, ship based fracking, subsea cementing

    Why don't they have a hawser left on the rear of the flukes with a bouy so you can hook up and pull it out backwards?
    10MRT shooters do it 60 times, in two directions and at two speeds.
