And there you have nailed why a
risk analysis /
probablistic risk assement is performed as part of a bigger risk management program. In addition it would be required by OSHA/EPA to conduct a
PHA/RMP for the rig. The PHA is, at it's most basic form, a "What if.." analysis. I've been trained to use the
HazOp method, but I would think that a
FMEA would be a better choice for an off-shore rig. I'm sure there are plenty of people on this board who have sat through a PHA, so let this accident be a reminder to you that while they may be the most boring meeting you've ever attended, they serve an important purpose.
And just in case anybody misunderstands what an engineer does, we are tasked with designing & building processes and equipment to meet all laws, regulations, industry standards, and specific prcoess specifications while ensuring public and environmental safety for the most cost effective price. As an example, it would be safer if all cars on the road were outfitted like a presidential limo, able to take an anti-tank missle and keep on driving. However, no one would want to pay for that, so it is engineered to be as light as possible, to obtain a certain performance specification, and meet a general price point, while ensuring that Mom, Dad, and the kiddies arrive safely at their destination or if involved in an accident, be able to walk away from it.
More often than not, its some VP suit that just got the ir MBA raising hell about the cost and wanting it done for cheap.
FAST
GOOD
CHEAP
Pick two of the above... the third is getting kicked to the curb.
