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.

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 1.Characterize Vessel Traffic Utilizing Cook Inlet in 2010 Base Year (≥ 300 Gross Tons), 2.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
25
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%
26
45 450 million gallons of persistent oil were move in 2010
27
566 million gallons of non-persistent oil was moved in 2010
29
Spill & Causality Study Objectives Studied Historical Incidents and Vessel Traffic to Define: 1.Baseline (2010-2014) and; 2.Projected (2015- 2020) annual spill rate Scenario Development
30
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
31
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.
32
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
