BOE’s Chery Anderson has alerted us that the Petrobras P-33 platform, which had been shut-in at the direction of the Brazilian regulators, has resumed production. Unfortunately, as has been the case with many post-Macondo articles, the author felt compelled to link the Petrobras problem to deep water.
…the accident once again raised concerns about the safety of deep-water oil output in the wake of last year’s disaster in the U.S Gulf of Mexico.
Contrary to popular opinion, water depth was a relatively minor factor in the Macondo blowout, and had nothing to do with the maintenance issues at the P-33 and other Campos basin facilities. Shallow water was a more significant contributing factor to the Montara blowout (batched completions, mudline suspensions, and two-stage platform installation) than deep water was at Macondo.
Access to shallow water blow out has been sometimes worse than deep water, when the rig or part of the rig collapse on top of the BOP ! so what BOP cap can you deploy ?
Further shallow water is difficult without a moored vessel, DP vessel in shallow depth are unworkeable on DP for drilling activities,and somehow 50 K barrels + gas blowing to the surface make it impossible for vessels to work on top or near the well. The Norwegian Gov. was quick to focus on more general issues and not bring the “deep water” as center stage. How are the energy ministers of countries like Norway(not EU) Denmark, Holland, France, Belgium perceive a blowout risk analysis West of the Shetlands ? when the application of an operator indicates impact as far as UK Norfolk coast ?
Excellent points.
