The catastrophic BP Macondo blowout three years ago revealed the dangers of deepwater drilling in the U.S. Gulf of Mexico, where critical equipment can be located a mile underwater.

After Macondo, President Obama appointed Michael Bromwich to help reorganize the former U.S. Minerals Management Service and rewrite offshore-drilling rules. Bromwich, now managing principal of The Bromwich Group, will highlight new developments.
