This is an excellent commentary. Questions have arisen and nothing is concluded! DNV, have published a ‘sitting on the fence’ report.
Nothing conclusive, plenty of conjecture! Beautiful drawings!
Are Cameron drawn into the conflict? Have they provided A BOP BSR which cannot perform its function?
I’m also very interested in the fact that all of the Rams on the BOP show erosion. This is only possible if the DP ‘collapses’ or all Rams were worn. Did the collapse occur after shut-in? Too many questions to ask and too many unanswered by DNV. They simply speak of upward forces offsetting the position of the DP causing BSR ineffective closure and seal. This is something for Cameron to address. Surely, Cameron never expect the pipe to be centralised!!
Nothing in the report offers a timescale of possible BOP events related to the blowout.
