5 What is Important to Companies? 2010 USA Companies $250M to $405B #1 Collaboration Software & More Efficient Processes 5

6 Structural PipeStress Why Have Integration Across Disciplines? Faster Design: Transfer Piping and Support Loads in hours not weeks. Considers Structural Sway & Stiffness for more accurate, safer designs Less Assumptions with more Accurate, Realistic Engineered Design Early clash detection Safer Structure, Piping, and Equipment Potential Cost Savings on Pipe Supports and Steel Structure Structural Engineer Pipe Stress Engineer 6

7 The problem is consistent in the Plant Market 7

8 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. 8

9 Importance of Structural Integration - Case Study Lungmen Nuclear Power Project Taiwan Power Company Is it Safe? Problem: Disconnected Main Steam Piping & Structural design = Dynamic Seismic Phasing Issues, grossly inaccurate Structural flexibility and pipe support loads Solution: Coupled Structure & piping gave reduced seismic loads at Turbine, more accurate pipe support design, greater confidence in static & dynamic analysis design Courtesy : Stone & Webster Inc., A Shaw Group Company Y X Z 9

10 Importance of Structural Integration - Case Study Queensland Alumina Pty (QAL) 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 Is it Safe? How expensive are Repairs? 10
