This is from Watts Up With That?  A detailed look at what happened at the Deepwater Horizon drilling rig, that we have been hearing so much about lately…

Jimmy Haigh, a geologist by trade, sends along a PDF that is a compilation of on the scene photos taken right after the explosion and in the following two days. I’ve converted it to web format. These were taken by people on the scene during the rescue and firefighting operation. There’s also a narrative, done by a person ‘in the know’. You won’t find this at AP or Reuters.

Taken shortly after the explosion. Note the mast is still intact, visible through the flames. You may have heard the news in the last week about the Deepwater Horizon drilling rig which caught fire, burned for two days, then sank in 5,000 ft of water in the Gulf of Mexico. \”….

The rig represents the cutting edge of drilling technology. It is a floating rig, capable of working in up to 10,000 ft water depth. The rig is not moored; It does not use anchors because it would be too costly and too heavy to suspend this mooring load from the floating structure. Rather, a triply-redundant computer system uses satellite positioning to control powerful thrusters that keep the rig on station within a few feet of its intended location, at all times. This is called Dynamic Positioning.

The rig had apparently just finished cementing steel casing in place at depths exceeding 18,000 ft. The next operation was to suspend the well so that the rig could move to its next drilling location, the idea being that a rig would return to this well later in order to complete the work necessary to bring the well into production.
