    The problem is consistent in the Plant Market

    EPC # 1 There are some significant disconnects between the pipe stress folks and the structural folks. As far as conveying information from pipe stress to Structural, we typically provide the preliminary structural steel drawings to pipe stress for them to mark up loads on it. This is extremely inefficient. Also, piping should try to get as much structural steel put onto the steel drawings so that detailing, fabrication and erection can be done in a single pass

    EPC #2 We have some serious frustrations in the way piping designers do their work, interfacing with structural and mechanical. I know the current process is disjointed, but it is all our tools provide us.

    EPC #3 - We have standard loadings that take care of the major stuff. The thing that is a killer is the special case stuff. The thermal loads and piping movements, spring supports, anchor points etc. These types of things have special details, as well as high loads. In addition, a structural engineer cant guess where these things are going to be or what they will look like. This has to come from the Piping Engineer and we have to sort through drawings. Most of the time this info gets to structural at best just before you issue the drawings. Sometimes it is after the first fabrication release has been sent out and you have to revise the drawings.

    Solution: Coupled Structure & piping gave reduced seismic loads at Turbine, more accurate pipe support design, greater confidence in static & dynamic analysis design

    US$0.5M/day in losses if digestor unit offline

    Short pump life sometimes in minutes

    Original design had capacity of suction nozzle being 5kN Actual suction nozzle load was

    30kN (6x over design) Designed for 1.5mm of steel

    displacement Actual steel movement was 3mm

    Displacement of the steel structure and fluid pulsations caused excessive nozzle loads (pump failure) requiring US$200k in additional steelwork and new supports
