ANCHORAGE PORT MODERNIZATION PROJECT Port of Anchorage Overview • Landlord Port / Department of the Municipality of Anchorage • Cargo: Petroleum, Cement, Container, Project Cargo • Critical to Alaska (~3.5M tons of cargo in 2014) – 74% of all in ‐ bound non ‐ petroleum freight thru Southcentral ports – 95% of all refined petroleum products moving thru Southcentral ports • Dept. of Defense Designated National Strategic Seaport
ANCHORAGE PORT MODERNIZATION PROJECT Existing Port of Anchorage
Anchorage Port Modernization Project PROJECT ENVIRONMENT
ANCHORAGE PORT MODERNIZATION PROJECT Conditions in the Knik Arm of Cook Inlet • 40 foot tidal range • Tidal currents and eddies • Glacial sediment • Ice flow and encasement • Endangered beluga whales
ANCHORAGE PORT MODERNIZATION PROJECT Existing Wharf Pile Conditions as of 2014 Min. Age Percent Terminal/POL Thickness (years) Loss Observed Terminal 1 54 0.15” 67% POL Terminal 1 50 0.15” 67% Terminal 2 46 (avg) 0.20” 55% Terminal 3 40 (avg) 0.18” 59% POL Terminal 2 20 0.13” 71%
ANCHORAGE PORT MODERNIZATION PROJECT Pile Jacket Repairs as of 2015 • Total number of Wharf Piles = 1,423 • Total number of Wharf Piles Jacketed = 462 (32%) – 2004 to 2011: Estimated 10 – 1 yr jacket life – 2012 to Present: Estimated 15 – 20 yr jacket life • Total number of Wharf Piles to be Jacketed = 961 (68%) • Spending Approx. $3M/yr to temporarily “fix” 100 piles/yr
ANCHORAGE PORT MODERNIZATION PROJECT Jacket Repair Limitations • Primarily a vertical capacity enhancement • Does not improve the seismic resilience of the Port – Simply “ band ‐ aids ” a structure not designed to current codes – Continued risk of sediment liquefaction during EQ • One ‐ time fix
ANCHORAGE PORT MODERNIZATION PROJECT Could be worse – wood piling!
ANCHORAGE PORT MODERNIZATION PROJECT Funding Environment • Previous Port Intermodal Expansion Project – challenges and perceptions • Fiscal Uncertainty • Understanding of the importance and the conditions of the Port
ANCHORAGE PORT MODERNIZATION PROJECT Project Team & Goals Project Team – Owner: Municipality of Anchorage / Port of Anchorage – PM/CM: CH2M ‐ HDR Project Goals – Replace Container Terminals 2 & 3 • Minimize investment in the North Extension – Provide modern, safe, and efficient port facilities – Provide for future growth • Support larger vessels • Allow for deeper draft ( ‐ 45’ berth depth)
ANCHORAGE PORT MODERNIZATION PROJECT Project Constraints Operational Constraints • Keep one Petroleum Oil Lubricant (POL) terminal in operation at all times • Keep existing container terminals operating until new terminals are complete • Must complete both container terminals once started Seismic Design Criteria • ASCE/COPRI 61 ‐ 14 • Two seismic berths to a higher seismic performance level – T2 & POL1 Funding Constraints • $127M Initially Available
ANCHORAGE PORT MODERNIZATION PROJECT Project Stakeholders • Municipality of Anchorage (MOA) • Cook Inlet Tug & Barge – Geotechnical Advisory Commission (GAC) • Southwest Alaska Pilots Association • Port of Anchorage (POA) • US Army Corps of Engineers • Totem Ocean Trailer Express (TOTE) Alaska District (USACE) • Matson CH2M/HDR Project Team • • ABI Cement • Flint Hills, Tesoro, Crowley, Delta Western, AFSC, Kirby
Anchorage Port Modernization Project STATUS
ANCHORAGE PORT MODERNIZATION PROJECT Anchorage Port Modernization Project Status Action Description Status Develop Charrette with follow on development of 3 Concept Plans Completed Concepts Select Municipality selects the concept and initiates the project Completed Concept Preliminary Concept refinement, develop permitting strategy, refine On ‐ going Engineering procurement strategies. Collect survey, aerial mapping, geotechnical, environmental, ship operations, hydrological, hydro ‐ acoustical and pile driving data for use by future Designers of Record Permitting Engage in the APMP Permitting process Initiating Design Procure Designer(s) of Record Contracts through the Not Started Municipality and prosecute designs Construct Procure Construction Contracts through the Municipality Not Started and prosecute construction efforts
Anchorage Port Modernization Project CONCEPT DEVELOPMENT AND OVERVIEW
ANCHORAGE PORT MODERNIZATION PROJECT Concept Planning Charrette • Charrette was held at the Port over a week • Four (4) concepts were presented • Information included concept layouts, construction sequencing, and estimated costs and durations • Potential value added alternatives were proposed & evaluated • Evaluation criteria and weights were pre ‐ determined • Three concepts were selected for further development • All concepts included stabilization of the North Extension and upland relocation of the functions located on Terminal 1
ANCHORAGE PORT MODERNIZATION PROJECT Selected Concept – Concept D ‐ The Anchorage Port Modernization Project (APMP) • Lowest upfront and lifecycle costs • Minimizes future maintenance dredging • Allows for future deeper draft ( ‐ 45 ft. berth depth) by moving off shore • No construction of interim berths • Shortest construction period • Maintains two (2) Petroleum Oil & Lubricant (POL) berths for majority of the construction • Least amount of tenants moved during construction • Provides additional acreage for tenants
ANCHORAGE PORT MODERNIZATION PROJECT PHASE 1: North Extension Stabilization Step 1 + POL 1 • Construct new POL1 (south of POL2) • Stabilize North Extension shoreline, Step 1
ANCHORAGE PORT MODERNIZATION PROJECT PHASE 2: Terminal 1 + Terminal 2 • Relocate existing T1 functions to landside • Construct new Container Terminal 1 (outboard of existing Terminal 1) • Construct new Terminal 2 (outboard of existing Terminal 2)
ANCHORAGE PORT MODERNIZATION PROJECT PHASE 3: POL 2 • Construct New POL2 (outboard of existing POL2)
ANCHORAGE PORT MODERNIZATION PROJECT PHASE 4 + 5: North Ext. Stabilization Step 2 + T3 Demo • Stabilize North Extension shoreline, Step 2 • Demolish Terminal 3
ANCHORAGE PORT MODERNIZATION PROJECT Funding Requirements Proposed Funds Phase Task Cost Fund Construction Required Source ½ North Extension Stabilization and 1 $127 M $0 In hand 2017 ‐ 2018 Replace POL 1 (fuel and cement) $298 M Statewide 2 Replace Terminal 2 and Terminal 3 $298 M 2018 ‐ 2022 GO Bond 3 Replace POL 2 $35 M $35 M Various 2019 or later Subtotal $460 M $333 M Complete North Extension 4 $88 M $88 M Various 2019 or later Stabilization 5 Terminal 3 Demolition $8 M $8 M Various 2022 or later Total $556 M $429 M
Anchorage Port Modernization Project LAND BASED DATA COLLECTION AND PRELIMINARY ENGINEERING
ANCHORAGE PORT MODERNIZATION PROJECT Completed Activities • Probabilistic Seismic Hazard Analysis • Port Survey Control and Boundary Survey • Topographic Survey at proposed construction locations • Port Photogrammetric Mapping • Land side and marine side Geotechnical Investigations • Land side Environmental Characterizations (Phase I and II) • Programming for replacement buildings • Initial Ship Simulation and Pilot Study • Geotechnical Advisory Commission Study • Development of overall permitting strategy • Procurement of Pile Test Program
Anchorage Port Modernization Project TEST PILE PROGRAM
ANCHORAGE PORT MODERNIZATION PROJECT Test Pile Program • Scope of Work – Gather Marine Side Geotechnical Data – Install Indicator Test Piles at 10 locations • Evaluate Pile Drivability • Estimate Pile Capacity • Evaluate Hydro ‐ acoustic Noise Attenuation methods • Kiewit Infrastructure West Co. awarded contract in August 2015 28
ANCHORAGE PORT MODERNIZATION PROJECT Planned Location of Test Piles 29
ANCHORAGE PORT MODERNIZATION PROJECT Hydro ‐ acoustic Monitoring • Scope of Work – Establish Noise Baseline without suppression systems – Evaluate two types of systems • Confined Bubble Curtain • Resonator System • Approach – Quantify levels of underwater noise for various installation methods • Different Pile Driving Hammers (vibratory, hydraulic, diesel) • Monitor at different distances from source 30
ANCHORAGE PORT MODERNIZATION PROJECT Noise Suppression Systems Confined Bubble Curtain • Confinement used because of water currents • Several levels of free ‐ rising bubbles Resonator System • Encapsulated air bubbles, tuned to specific frequencies and arranged in specific configurations (Helmholtz resonance) 32
