what was that explosive cord, that used to make easy work of stuff. That and blowing the thing up.
worked on a couple of projects where we removed old well structures with explosives, putting them in place with the ROV.
sounds like fun but the vessel moved off 6 miles, where is the fun in that - we hardly saw or heard anything.

On a side note the Berirut explosion, bloody hell. I have seen some big bangs in my time but holy crap (i do intentionally say that with biblical reference) that was like Hiroshima. Which again is also especially significant as we have just had VJ day.
