re: #570 Gus 802

If it takes them three months then there’s going to be much more serious problem.

NOAA Assessment of Deepwater Horizon Incident, Gulf of Mexico

Workers finished fabricating the containment chamber portion of the collection dome that will be deployed to the sea floor to collect oil as it escapes from the well. Work will now begin on the piping system that brings the oil to the surface for collection; this method has never been tried at this depth before. The first rig to be used for drilling a relief or cut-off well is on site and should begin drilling approximately a mile from the well head on Friday. The relief well will not be complete for several months. Responders are still figuring out new ways to use Remotely Operated Vehicles (ROVs) to try to trigger the blowout preventer (BOP), a series of valves that sits at the well head. These efforts will continue concurrent with the collection dome and relief well(s). Good weather today allowed for both skimming operations and aggressive aerial application of dispersants - over 50,000 gallons of dispersant have been applied to the surface oil in the last two days. Patches of surface oil were captured with fire-retardant boom and ignited (in situ burn).

So we have again several month including a procedure that has never been attempted at this depth before.
