PORT ACCESS ROUTE STUDY (PARS)PORT ACCESS ROUTE STUDY (PARS)

•PWSA requires Coast Guard to conduct a PARS before establishing new or adjusting existing fairways or TSS’s.

•Consult/coordinate with Federal, State, and foreign state agencies (as appropriate) and maritime community representatives, environmental groups, and other interested stakeholders.

•Primary purpose of this coordination is, to the extent practicable, to reconcile the need for safe access routes with other reasonable waterway uses.

•PARS process (complete or modified) may be used to determine and justify if safety zones, security zones, recommended routes, regulated navigation areas and other routing measures should be should be created.

• Marine Spatial Planning- Characterize existing MTS/Shipping Routes

- Balance multiple uses- Ensure safe access routes

• Wind Energy Initiatives- Cooperating Agency- Navigational Conflicts- Cumulative Impacts

IMPACTS TO NAVIGATION IMPACTS TO NAVIGATION

SUMMARY AND CONCLUSIONSSUMMARY AND CONCLUSIONS

Impact to Shipping•Will increase risk of allision•May increase risk of collision•May increase risk of grounding

Establishment of WEAs•R-Y-G is defensible•Leaves moderate conflicts available for further study•Highlights area of concern

Cumulative Impacts of Wind Farms•A primary objective of ACPARS assess cumulative impacts to MTS•Displacement, Funneling, Increased Density•Cascading effects

SUMMARY AND CONCLUSIONSSUMMARY AND CONCLUSIONS

Establishment of Routing Measures•Existing system of traditional routes is complex•Determining nav impacts as a result of a significant change to routing is beyond capabilities of the WG•Routes should not be created without full analysis

Tug and Barge Routes•Most direct and safe route•Vary based on weather, sea state and depth of water•WEAs could force tug and barges further inshore or offshore

― Increase congestion at port entrances

― Higher sea states offshore

― Mixing of vessel types (slow vs. fast moving)

SUMMARY AND CONCLUSIONSSUMMARY AND CONCLUSIONSDeep Draft Routes•Coastwise routes further offshore

― Higher conflict with next round•Higher conflict at harbor approaches•Proposed WEAs would require modification or elimination of some routes

Risks of Postponing Assessment of Navigational Impacts•EA for leases only evaluates impacts due to site assessment & site characterization activities•Navigation Safety Risk Assessment → COP•Removal of areas late in process could hamper wind development efforts•USCG has recommended impacts be evaluated prior to establishing WEAs

Other Offshore Energy Installations•Emphasis currently on Wind•Future “All of the Above Approach” for Oil/Gas, hydrokinetics, other uses

PHASE 3- MODELING AND ANALYSISPHASE 3- MODELING AND ANALYSIS

• Develop a GIS based model to predict traffic density and traffic patterns given alternative siting scenarios

• Determine the resultant nav safety risk Increased density Mixing of vessel types Risk of allision Risk of collision Evaluate mitigation measures

• Has commenced – PNNL- BOEM funded- USCG provided AIS data for

2010, 2011, and 2012

• Expert panel for PNNL modeling and analysis

• Technical panel for PNNL modeling and analysis

PNNL Deliverables and MilestonesPNNL Deliverables and Milestones•Data Analysis

•Model Setup

•Decision Tree and Scenario Development

•Presentation of interim results –- May - June 2013, Washington, DC

•Deliverables – November 2013- Processed AIS Data- Visual displays of existing shipping routes and operational areas, with BOEM lease blocks

- Numerical model in executable form- Final report- Presentation of final results – Washington, DC

FUTUREFUTURE•Publish 2nd Interim Report/comment period after PNNL

interim results

•PNNL finishes analysis and modeling tool (Phase 3)

•Publish Final ACPARS report/comment period

•Public outreach to present report/gather input concerning recommendations

•Provide input to BOEM concerning all the WEAs

•PHASE FOUR - Implement study recommendations-Routing measures-IMO papers-Regulations-Other mitigation measures
