Washinton State University/Manchester Fuel Depot Senior Project
- 1. Manchester Fuel Depot Pipeline Support Renovation Danny Cornutt Beau Maben Giovanni Juarez Barrett Makrecky © Washington State University Mechanical Engineering 2013. Please do not reproduce without the expressed written consent of Washington State University- Bremerton
- 2. Project Goals – Key points taken into consideration during design Overview Background– Fuel Depot location and current condition Impact – Fuel spill affect on local region Deliverables – Support type, construction process, timeline and cost report Conclusion – Summary of project, next steps toward construction 1 2 3 4 5 WSU Engineering 2
- 3. Manchester Fuel Depot • 37 monuments with nylon supports • 2 monuments with fixed points • 775’ pipeline • 1- 10” diameter • 1- 14” diameter WSU Engineering 3
- 4. Current State • Nylon pads buckling and failing • Difficult visual inspection • Possible pinhole leaks developing • Corrosion developing • Costly to maintain WSU Engineering 4
- 5. Impact • Marine life • Fisheries • Whale pods • Public beaches • Navy operation • Native American tribes • Cost http://canadiantruths.files.wordpress.com/2008/05/duck2.jpg http://www.ecoosfera.com/wp-content/imagenes/dead-fish1.jpg http://imagecache6.allposters.com//LRG//%5C27% 5C2750%5CTQ1TD00Z.jpg http://lh6.ggpht.com/_1RasRrVkr5Y/R4L- FieJJwI/AAAAAAAAAEk/ndpNIu2Epuc/seattle_alki_beach_crowd http://upload.wikimedia.org/wikipedia/ commons/d/d2/Aerial_Bremerton_Shipyard.jpg http://www.hickerphoto.com/images/500/alaska_f76t4736.j WSU Engineering 5
- 6. Project Goals • Lifecycle of 30+ years • Proven solution • Cost effective solution • Minimize maintenance • Minimize project timeline WSU Engineering 6
- 7. • Off the shelf • Welded T-shoe support • Graphite slide plates • Support guides Support Type WSU Engineering 7
- 8. Static Friction Analysis (Graphite) Stress Plot Factor of Safety (blue means > 3) • Assumed material 1020 Steel WSU Engineering 8
- 9. Pipeline Deflections • Assumed material 1020 Steel Pipe Static Displacement Plot WSU Engineering 9
- 11. Welding Stress 0 20000 40000 60000 80000 100000 120000 Bending Shear 2901 1451 109939 53084 PSI Alloy Steel Yield Strength Alloy Steel Tensile Strength WSU Engineering 11
- 12. Project Direction Options Basic Construction • Keep same monuments, change pipeline elevation • Build new monuments • Pour concrete cap • Modify Existing Monuments Lifting • Crane operations • Jacking systems • Monuments- Temporary Supports WSU Engineering 12
- 13. Proposed Design • Reduce number of monuments • Use existing monuments • Cut down to desired height • Use proven welded T-cradle support type WSU Engineering 13
- 14. Monument Calculations Reducing Monuments Unknowns and spreadsheets Load on the monuments 7694 lbs Average stress = F/A = 16 psi Maximum compressive stress = 28 psi Ultimate strength of concrete = 2900 psi Minimum factor of safety = 103 Weight force Friction force WSU Engineering 14
- 15. Soil Capacity Calculations Necessary Soil Capacity: 987 psf Averages: 2000-6000 psf WSU Engineering 15
- 16. Construction Process • Use existing Monuments for support • Install Temporary support • Work between supports • Cut old monuments supports once complete WSU Engineering 16
- 17. Installation Detail • Cut down monuments • Install t-cradle pipe supports • Elevate baseplate to proper height • Grout at desired elevation WSU Engineering 17
- 18. Finished Product • Minimal material to coat • Sealed from environment WSU Engineering 18
- 20. • Use proven support type • Reduce unneeded monuments • Project duration is 37 days • Projected cost was $300,000 to $500,000 • Actual project estimate is under $179,000 • Simple, proven system for 30+ years of operation Summary WSU Engineering 20
