Future Proofing Your Business Earthquake Risk Joshua Marrow

Future Proofing Your Business - Earthquake Risk Joshua Marrow, P. E.

Topic of Discussion • Winery Seismic Vulnerability Research • M 6. 0 South Napa Earthquake • Future Proofing For Earthquake Hazards Not earthquake proof, but earthquake resilient

Winery Earthquake Risk Profile • Barrels • Facility type/number • Tanks • Winery occupancy • Buildings • Time of year • Process Systems • Inventory value • Case Goods • Cost/time for recovery

Seismic Vulnerability Research Half-Scale Shake Table Studies Cal Poly SLO in 1997 and UC Berkeley in early 2000

Seismic Vulnerability Research Full-Scale Shake Table Studies Richmond Field Station at UC Berkeley in early 2000

Seismic Vulnerability Research Full-Scale Shake Table Studies Two-barrel rack demonstrated poor seismic performance 2 -BBL, 4, 5 -High 4 -BBL, 6 -High

M 6. 0 South Napa Earthquake Seismic wave directivity to the north

M 6. 0 South Napa Earthquake

Key Issues and Lessons • 3: 20 AM – No deaths Life safety risk higher during day • August 24, 2014 Product was in the vineyards • Low structure damage Modern buildings performed well • Barrel loss profound Steel bbl racks, pyramids ok • Repeat, relearn 2003 San Simeon, 2000 Yountville, 1989 Loma Prieta… Turley Winery, 2003 San Simeon Earthquake

Case Study – 2 BBL vs. 4 BBL

Earthquake Resilience Strategy • Seismic Benchmark Seismic risk study • Inventory Understand your exposure • Prioritize Where to put the resources • Best Practices What have we learned so far • Invest in Mitigation Be smart about it, seek advice

Earthquake Resilience Strategy • Buildings Building codes improve • Tanks Anchorage recommended • Barrels 4 -BBL Rack, short stacks… • Disaster Prep Facility study, annual training • Study Improvements Bite-sized mitigation, no “perfect” solution

The Colbert Top 10 EQ Strategies “Marrow” 1. Keep the public away from the barrels 2. Four Barrel Racks vs. Two Barrel Racks 3. Limit stack heights where possible 4. Orient stacks with bilges out, heads end-to-end 5. Restrain top level barrels to their rack 6. Anchor wine tanks and consult tank vendors for design basis 7. Independent support for catwalks (no tank support) 8. Study collapse patterns and develop EQ response program 9. Install “shark cages” throughout the barrel room 10. Install seismic instruments and PA system Avoid “solve all” solutions that are impractical and costly
