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 can’t 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.

Lungmen Nuclear Power ProjectTaiwan Power CompanyProblem: Disconnected Main Steam Piping & Structural design = Dynamic Seismic Phasing Issues, grossly inaccurate Structural flexibility and pipe support loads

Courtesy : Stone & Webster Inc., A Shaw Group Company

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
