  1. Briefing at: Consequence Analysis Workshop October 30, 2012

  2. What is a Risk Assessment? • Project Background • Work Plan • Vessel Traffic Study Results • Outreach Efforts • Questions?

  3. What is a Risk Assessment? • What can go wrong?

  4. What is a Risk Assessment? • How likely is it?

  5. What is a Risk Assessment? • What are the impacts?

  6. What is a Risk Assessment? • Can the risk be reduced or the impact mitigated?

  7. Project Background • 1999 Safety of Navigation Forum – Homer • 2000 Ports and Waterway Safety Assessment • 2006 Sea Bulk Pride Grounding • 2006 Cook Inlet Vessel Traffic Study • 2007 Navigational Safety Forum – Anchorage • 2008 Risk of Vessel Accidents and Spills • 2009 Aleutian Island Risk Assessment

  8. Project Background 2007 Navigational Forum – Consensus Points • Cook Inlet RCAC should move forward with a risk assessment, • Engaging in the political process will be necessary to obtain funding, and • Public participation and outreach will be critical to the success of the risk assessment.

  9. Project Background National Academy of Sciences Transportation Research Board Special Report 293

  10. Work Plan • Limits and Bounds • Organization and Management Structure • Project Steps/Tasks • Timeline • Deliverables

  11. Limits and Bounds Substances • Oil • Cargo, Crude Oil or Refined Product • Fuel, Bunkers

  12. Limits and Bounds Vessel Types • Containerships • Bulk carriers • Gas carriers • Car carriers • Cruise ships and Ferries • Crude oil tankers • Product tankers • Tank barges and tugs • Cargo barges and tugs • Chemical carriers • Tugs • Offshore Supply Vessels • Mobile Drill Rigs • Government Vessels

  13. Limits and Bounds Accident Types • Collisions • Allisions • Powered Groundings • Drift Groundings • Foundering • Structural Failures • Mooring Failures • Fires

  16. Organization Advisory Panel • Fisheries • Local Government • Mariner, Pilot • Mariner, Salvor • Mariner, Containerships • Mariner, Tug and Barge • Mariner, Tank Ship • Mariner, General • Non-Governmental Org. • Resource Manager • Subsistence User

  17. Tasks • Project Communications • Facilitate and Support Manage Team and Advisory Panel • Vessel Traffic Study • Baseline Accident and Spill Study • Consequence Analysis Workshop

  18. Tasks • Identify Risk Reduction Options • Evaluate Risk Reduction Options • Prioritize Risk Reduction Options and Prepare a Final Report

  19. Timeline

  20. Deliverables • Vessel Traffic Study (Completed) • Spill and Causality Study (Completed) • Consequence Workshop Report (Fall 2012) • Risk Reduction Recommendations • Final Report

  21. Vessel Traffic Study Objectives • Characterize Vessel Traffic Utilizing Cook Inlet in 2010 Base Year (≥ 300 Gross Tons), • Predict Vessel Traffic Until 2019

  22. Vessel Traffic Study Findings • 480 ship port calls • 80% of the calls were made by 15 ships • 218 million gallons of persistent oil and 9 million gallons of non-persistent oil were moved on 83 tank ship voyages to or from the Nikiski and Drift River terminals

  23. Vessel Traffic Study Findings • 36% of all persistent oil moved was fuel oil on dry cargo ships calling at Anchorage • 102 oil barge transits moved 366 million gallons of nonpersistent oil; the greatest amount of oil moved by a single vessel type

  24. Vessel Traffic Study • AMHS ferries 23% • Horizon Lines container ships 22% • TOTE Ro-Ro cargo ships 22% • Crude oil tank ships 15.5% • Refined product tank ships 4% • Bulk carriers 4% • Gas carriers 2.5% • Cruise ships 3% • Fish industry 1%

  25. 45 450 million gallons of persistent oil were move in 2010

  26. 566 million gallons of non-persistent oil was moved in 2010

  27. Spill & Causality Study Objectives Studied Historical Incidents and Vessel Traffic to Define: • Baseline (2010-2014) and; • Projected (2015- 2020) annual spill rate Scenario Development

  28. Spill Rates • Vessel Types • Tank Ships • Tank Barges • Non-Tank/Non-workboat vessels (Cargo, Cruise ship) • Highest forecasted spill rate of 1.3 per year • Workboats (OSV, Towboat/Tugboat) • Highest baseline spill rate of 0.96 per year • Sum of the four vessel types is 3.9 spills per year

  29. Scenarios • Defined for 2,112 unique combinations of vessel types and spill factor subcategories. • Majority of scenarios have low to very low relative risk level. • Tank ships have lowest baseline spill rate, but have the most risk from an oil spill.

  30. Scenarios for Workshop • Total of 6 scenarios • 2 Upper Cook Inlet: Knik Shoal & Port of Anchorage • 2 Mid Cook Inlet: Drift River & Nikiski • 2 Lower Cook Inlet: Barren Islands & Port of Homer

  31. Outreach Efforts • Email Contacts • Advisory Panel Solicitation • Public Meetings • Website
