British Petroleum (BP) has a collection of 'bots' or ROV's, remotely operated vehicles, tethered underwater robots operating in the Gulf of Mexico near the blown out Macondo Well site, while they attempt to either plug the leak or at least find ways to recover and siphon off the leaking oil.
Sitting on top of the well pipe projecting from the seabed is the BOP, or Blow Out Preventer, the large steel 450 ton apparatus that you may have seen in various photographs and videos from BP's Live Feed as they recently cut off the top of the riser pipe that ran from the BOP to the Deepwater Horizon platform before it burned and sank.
There has been much speculation lately that the well bore is damaged below the seabed and that oil is leaking out of the well into the seabed underneath and around the BOP.
Keeping in mind that the BOP weighs 450 tons it would seem that if the seabed is becoming saturated with oil leaking through it that is only a question of time before the seabed will no longer have the structural strength to support the weight of the BOP and that it could fall off the top of the well pipe it is sitting on, releasing an uncontrolled and uncontrollable flow of oil into the gulf with no way of plugging or stopping it.
BP denies that oil or gas are leaking from cracks in the sea floor on the bottom of the Gulf of Mexico.
This video was recorded from the Viking Poseidon ROV 1 on June 13th, 2010, and appears to show bursts of oil leaking from cracks in the seabed.
