    24-level building tower fire in West London

    A very weak defense, because that is contrary to how codes work. Codes can't possibly ban the infinite number of potentially inflammable materials that are known to man today for use as building claddings, or ban all new ones that might get invented on the morrow. Codes might list approved...

    It appears that the USS Fitzgerald collision may have been an "Engineering Disaster"...

    Doesn't seem to me like the lack of AIS coverage should have any bearing one way or another here. Richard Feynman's Problem Solving Algorithm 1. Write down the problem. 2. Think very hard. 3. Write down the answer.

    It appears that the USS Fitzgerald collision may have been an "Engineering Disaster"...

    Without intent of making lite of the situation, a communications outage may not always be referring to the equipment. Failure to communicate can be brought on by a number of root causes. http://www.navy.mil/navydata/nav_legacy.asp?id=174 Richard Feynman's Problem Solving Algorithm 1. Write...

    24-level building tower fire in West London

    No aluminum is not bursting into flames from the surges. Actually its the normal current that can cause sparks... eventually. Aluminum creeps more than copper. It has an expansion coefficient about 50% greater than copper, so turning an AL wired circuit on and off expands and constracts the...

    Biogas compressor

    I see "compressors" to mean he needs 2 compressors, most likely one discharging at 5barg the other at 18.5barg. Richard Feynman's Problem Solving Algorithm 1. Write down the problem. 2. Think very hard. 3. Write down the answer.

    Engineering Assessment During New Construction

    So essentially that code now says variance to roundness minimums are permitted, if approved by the engineer. That's great. Exactly as it should be. Richard Feynman's Problem Solving Algorithm 1. Write down the problem. 2. Think very hard. 3. Write down the answer.

    Above ground 4 hour test

    I can imagine this could be a perfect fit to something my dad always told me. You could be very cooperative, try to make this look like a real test, write it all down, stand on your head, do the calculations and prove there was no leak. Do all the work and submit it. And then they don't...

    Above ground 4 hour test

    Who said there was. If there was, then you've got no real test with ... records. I really want to see the volume in - volume out charts. Not buying. Richard Feynman's Problem Solving Algorithm 1. Write down the problem. 2. Think very hard. 3. Write down the answer.

    Above ground 4 hour test

    I know. But you have to realize that this has nothing to do with engineering or engineering judgement. However this is a continued risk to operations. You admit it isn't a proper test. The competent authorities aren't going to have a warm and fuzzy feeling about it. You have followed...

    Above ground 4 hour test

    Funny because IMO no pressure was ever held. It was cleverly balanced. Maybe it qualifies for operation at high pressure under an alternate demonstrated highest recorded pressure during operation, but I can't agree that it is a pressure test in the classic sense. Richard Feynman's Problem...

    Above ground 4 hour test

    So what is YOUR established acceptance criteria. Can't remember ever seeing "ran at test pressure for 4 hours". Kind of funny actually. the code does not categorically specify this Magic words. YES! CORRECT! THAT is YOUR JOB! To specify what is required. Sorry, but your understanding of...

    Pipeline next to road. ASME B31.3 or ASME B31.4

    NO your secruity concept is exactly the opposite of the facts. Nobody works inside chemical plants. OK, maybe 5 people on a routine basis. B31.3 is for pipe located behind the fence, controlled environments, inside chemical plants. If you are putting this water in a pond, basically it is...

    Pipeline next to road. ASME B31.3 or ASME B31.4

    You haven't made a connection to any kind of process. Did your "water" ever even get hot? Definitely not hydrocarbons, or any kind of hazardous liquid, anhydrous ammonia, or other hazardous chemical, correct? Or is it full of sulfuric acid, sodium hydroxide, cyanide or something? Are you...

    Above ground 4 hour test

    That's not a test. That's an untested system running at overpressure. All of us here know what a "pressure test" is and more or less how it should be done. It doesn't fit our common sense definition of a proper hydrotest, so basically it fails. Normally in a hydrotest both pressure and...

    I'm not directly involved with the production side, but ... you see and hear things, plus there's lots of data on the net, if you know where to look .. and you do look.
