Re: alcor’s 5747
There’s a bit more to unity of command than just the notion of having one superior. A useful discussion of the concept in the military domain can be found here:
www.strategicstudiesinstitute.army.mil/pdffiles/pub889.pdf
Like all management principles, it’s subject to interpretation and following it does not guarantee success – but ignoring it does raise the chances of failure.
I must confess that I have seen command/management structures that fill me with more confidence than those described in the alcor’s post, but that topic is going to be pecked to death by the lawyers so I’ll let it pass.
I do have some questions (real questions, not disguised assertions) in regard to the operations of these rigs:
-
How much time does a Driller have to react to an anomalous flow/pressure/volume reading? Minutes? Hours?
-
How is an order to activate the BOP issued, verified, and executed?
-
Anybody know the deepest depth at which a BOP has been activated, either operationally or under test?
-
Is it really true that BOP technology hasn’t evolved significantly since 1946? This paper:
www.iti.de/fileadmin/Ressourcen/Paper_und_Fachartikel/OMAE_Proceedings.pdf
draws some interesting conclusions.
Cheers,
