So Iâve been thinking about how to plug the leaking well. Iâve heard some people say that they should try to blow it up with dynamite or possibly an atom bomb. However, this will obviously cause more problems than it solves and I donât think that it will necessarily seal the well. My solution is a rather simple one. The pipe of the well needs to be cut as close to the bottom of the ocean as possible. After this is accomplished we will need a âplugâ with which to close the well. We will need a ship with a crane capable of lifting a few tons. From the ship a âplugâ possibly made out of metal (lead, iron, etcâ¦) on a chain weighing anywhere from 3-5 metric (the plug that is, not the chain) tons will be lowered towards the leak guided by underwater robots. The plug will be placed on the oil well. Here we will have a little problem due to the pressure of the oil gushing out. As such, the heavier the plug the better, in order to counteract the force of the gushing oil. After the âplugâ is placed on top of the leak we will need to seal the well. Perhaps creating a cement sarcophagus (not unlike the concept used at Chernobyl) and lowering it down will be a solution. Then additional material will be required to seal and bury the well. To me this seems like the most practical and cost effective way of sealing the well and stopping the leak. I have 100 % confidence that such a thing will work. It does not require any new technology, it is not a delicate operation and it is relatively cheap to implement.
