Why Improve Boston Harbor?

• New Panama Canal to come Online in Late 2014 – 55 Foot Depth ‐Will Allow 50‐Foot Drafts – Now Allows 39‐Foot Vessels.  Beam from 106 Now to 120

• Other Ports on Route Deepening – NYNJ to be at 50 Feet inOther Ports on Route Deepening  NYNJ to be at 50 Feet in 2015 and 55‐Foot Study Authorized.  Norfolk, Baltimore already at 50.  Miami Authorized to 50.  Savannah to 47.   Charleston d P t E l d t 45 d St d i D M t EU P tand Port Everglades at 45 and Studying Deeper.  Most EU Ports 

at 56 Feet and Suez Canal now at 78 Feet (2011) • Carriers Increasing Vessel Sizes in Trans‐Oceanic Routes to Save gCosts

• Road Traffic Congestion Worsens and with it Highway Maintenance and Air Quality IssuesMaintenance and Air Quality Issues

• Global Trade Volumes Projected to Increase

What Has Happened Since 2008?

• Civil Works Review Board met in August and September 2008 to g pConsider Boston Harbor

• Board requested additional Economic Studies of Depth Optimization

• Study Scope Approved 2009 and Studies Completed 2010 

dd l l d b d• Additional Analysis was Requested by Corps Headquarters

• Final Economic Reports Submitted in May 2012

Fi l D i D th f 47 F t f I M i Ch l• Final Design Depth of 47 Feet for Inner Main Channels Improvement to Conley Terminal Selected in September 2012

• Final Entrance Channel Depth of 51 Feet Selected November• Final Entrance Channel Depth of 51 Feet Selected November 2012.

Economic Reanalysis Framework Issues

Three Parts to Framework Reanalysis

(1) Landside Analysis – Where are the containers going and why.  How many more might come to Boston y y gby water?

(2) Waterside Analysis – What means used to ship to l h ll h b ?Boston – larger ships, small ships, barges?  

(3) Loading Factors – How will new Boston ships load?  Tidal advantage 1st in last outTidal advantage. 1st‐in last‐out.  

Landside Analysis (Task #1)

• Analysis of Current Shipping Conditions– Determine Current Origin & Destinations of boxes

– Use PIERS data for Boston and PONYNJ

– Conduct Sample of Shippers (200 shippers account for 80% of shipments)

– Interview Carriers using Boston and PONYNJ

– Develop Economic Model to explain current proportions of Boston cargo shipped through PONYNJ and project potential change in boxes that can go to Boston directlyBoston directly.

Waterside Analysis (Task #2)

Determine Means Available to Transport Boxes Shifted from PONYNJ to POBfrom PONYNJ to POB

• What Carriers?– Existing Carriers Calling on POB?– Carriers Calling PONYNJ and Currently Not POB?– Why Carriers are Calling on PONYNJ and not POB.

• What Vessels & Routes?What Vessels & Routes?• Trucking Firms Canvassed for Distance Costs and Volumes• Carrier Interviews Conducted to Collect Needed Information

– Both Carriers Currently Serving POB Interviewed– Seven Carriers that Call PONYNJ & Not POB Interviewed.

Vessel Loading & Sailing Drafts (Task #3)

• Determine Existing Vessel Distribution and Current Operating Practices on Vessel Loading and Sailing Drafts.Operating Practices on Vessel Loading and Sailing Drafts.– Boston First in/Last Out for North America– Boston Has Greater Tidal Advantage Than Most East Coast P t (9 5 F t 5 5 t NYNJ d 4 5 F t El h lPorts (9.5 Feet versus 5.5 at NYNJ and 4‐5 Feet Elsewhere along US East Coast)

– High Export Percentage Relative to Other East Coast Ports Encourages Greater Loading.

– Outbound Boston Cargo much Heavier than Inbound• Determine Future Vessel Loading and Sailing Drafts• Determine Future Vessel Loading and Sailing Drafts

– Drafts and Loading were Determined on Current Industry Practices and Weight of Cargo

– Boston Harbor Pilots and Carriers Consulted on Underkeel Clearance Requirements and Movement Restrictions 

Recommendation – 4 Improvements

• Main Channels Improvement: For Containership Access to Conley TerminalContainership Access to Conley Terminal

• Main Ship Channel Deepening Extension: For Large Dry Bulk Carrier Access to Massport g y pMarine Terminal

• Mystic River Channel: Deepen for Smaller D B lk C i A t M t’ M df dDry Bulk Carrier Access to Massport’s Medford Street Terminal

• Chelsea River Channel: Deepen Channel for• Chelsea River Channel: Deepen Channel for Liquid Petroleum Carriers

• Base Plan for Disposal - All Disposal at theBase Plan for Disposal All Disposal at the Massachusetts Bay Disposal Site

Main Channels ImprovementDeepening for Containership AccessDeepening for Containership Access

• Project Features 1. North Entrance Channel to 51 feet, widened at Finns Ledge Bend1. North Entrance Channel to 51 feet, widened at Finns Ledge Bend2. Main Ship Channel from Outer Confluence to Reserved Channel to 47 feet,

widened to 900 feet below Castle Island and 800 feet above. Widened further in the bends.

3. President Roads Anchorage Area to 47 feet4. Lower Reserved Channel along Conley Terminal to 47 feet5. Reserved Channel Turning Area widened to 1600 feet and deepened to 47 feet6. Conley Berths deepened to at Least 50 Feet

• Examined incremental depths of 42 to 50 feet MLLW – Optimized at 48 feet but no significant benefits increase above 47 feet

• Entrance Channel four feet deeper than inner channels for increased sea states and vessel motion

• Conley Terminal Berths will be deepened to 3 feet deeper than the channel by Massport for tidal navigationMassport for tidal navigation

• Benefits from shifting truck transport to containership transport

Existing 40-Foot Channels, Anchorage and Turning Basin – Deepen to between 45 to 50 Feet (2 to 5 Feet Deeper in Entrance Channel)
