Step #1 - Crude cut with giant clamps - Completed
Step #2 - Precise cut with diamond ribbon saw (to provide for good seal) - partially completed but saw stuck.
Step #3 - Lower docking assembly & pipe to seal top of BOP and move oil to surface - awaiting #2

Couple things give this a better than than the first dome:
a) tight fit against pipe means higher level of capture
b) cap fits onto BOP rather than sinking into the muddy ocean floor (the ocean "floor" is about hundred feet of silt).
c) Methanol injected into oil to prevent/reduce freezing
d) inner pipe for oil surrounded by larger pipe with warmed seawater to increase temperature of oil/gas.
