What you may not be aware of is that due to the long time it takes from when munitions are caught up in local fishermen’s nets for the authorities to collect and dispose of them, losing time and a days catch the fishermen for years have been without telling anybody dumping the munitions around and near the wreck. Before a coffer dam could be built these would have to be found disarmed and removed as their condition dating back 1st and 2nd world wars is unknown some being 250-500 Kg or more! Also the vibration of building the coffer dam even without this extra danger could set the lot off!Yes the water would be a problem. So how about this, build two cofferdams around the ship, an inner one and a big outer one and pump them dry. Now you fill the inner one with a whole lot of sand on top of the ship to keep bits from flying away. Then you fill the second one with sand as well to act as a compressible buffer between the explosion and the water. That should work and still make great video.![]()
There is another hazard which is phosphorous that has been coming to surface. This substance as you are probably aware catches fire when exposed to air not a good thing whilst in contact with bombs during pump out stage if it got that far of coffer dam build. Next idea?
