Port Development Scenarios Segment 1: Port Master Planning Master Planning Approach 13 May 2014 Formulation and Development of Port Development Scenarios
What is a Port Master Plan? Port Master Planning usually 20-30yr horizon but often revisited and should: Look into the future Discuss how a port should develop to meet demand Show integration with transport networks Address environmental constraints Ensure compatibility with adjacent land use Present a proposed Development Scenario The Development Scenario should: Be flexible to incorporate change Make best use of existing port assets Allow for effective phased development to match demand Include port zoning to cover both land and water areas, often by trade type Allow for future proofing of critical parameters: Berth depths Land areas Land connections Port zoning 6
The Port Master Planning Process 7
Port Master Planning General Principles 1. Look to optimise existing terminal 2. Identify bottlenecks Operating procedures Equipment Physical constraints (berth and yard) Trade consolidation 3. Confirm the need for new container terminal 8
The role of trade/demand forecasting One of the most important inputs to a port plan Prefaced by a market study Estimate the type and amount of cargo that will need to be handled Objectives of a demand forecast: Provide a basis for physical port plans Support economic and financial assessments Coupled with a vessel fleet analysis to establish design vessel fleet spectra to determine: Water depths Navigation and turning areas Berth type and length Reliability of estimates decreases as forecast horizon increases 9

Challenges facing existing ports: Inland Connections Land side infrastructure often constrained backs onto cities Existing transport connections may need significant expense to increase capacity often not the responsibility of the port owner/operator. Rail effective for containers, but typically dedicated consists. Gradient dependant. 21
Challenges facing existing ports: Inland Connections $7.2bn Khalifa Port UAE: Containers relocated to enable growth 22
Challenges facing existing ports: Environmental Conditions Assessment of sea level rise, storminess, subsidence, population growth and urbanisation 2005: Population exposure (2.2M) 2070: Asset value exposure (US$321bn) 1 Nicholls, R. J. 2008, Ranking Port Cities wit high Exposure and Vulnerability to Climate Change Extremes: Exposure Estimates. OECD Environment Working Papers, No.1 23
Challenges facing existing ports: Ocean water levels are rising Risen 120m in the last 21,000 years Global rise of 0.17m during the 20 th century Water body continues to expand Water exchange between oceans, glaciers etc continues Tectonic movements, ground water extraction Sea Level Trends 1993-2003 (Cazenave and Narem 2004) 24
Challenges facing existing ports: Are storms getting more severe? Considerable debate over whether storms are changing Lack of real data and only recent models Large historic variations No significant change in tropical storm numbers 1970-2004, except Atlantic 1 Observed changes in storms could be attributable to natural variation Observations suggest changes in H s over time that are latitude dependent 2 Storm surge has been shown to be effected, but driven by local conditions Reproduced from : Nobuhito Mori, T, Y.

(2010), Projection of Extreme Wave climate Change under Global Warming, Hydrological Research letters, 4, 15-19 25
Challenges facing existing ports: What could the impacts be? Increased downtime due to flooding and inundation of terminal areas, buildings and infrastructure Increased wave and storm surge activity Surface water drainage capacity Structural damage and durability (when combined temperature changes) Waves batter a merchant vessel stranded along the coast during a heavy storm in Valparaiso City, Chile, 121 km (75 miles) northwest of Santiago on July 6, 2010.

Port Development Scenarios Segment 2: Development Scenario Considerations 13 May 2014 Formulation and Development of Port Development Scenarios
Port Development Scenarios Segment 2: Development Scenario Considerations Functional Requirements of a new port 13 May 2014 Formulation and Development of Port Development Scenarios
Development Scenarios Finding a new site Deep sheltered water Good conditions for vessel manoeuvring Environmental conditions that maximise berth availability and minimise downtime (wind, wave) Availability (or ability to form) yard area Good transport links Good ground conditions Suitable existing land use and zoning Available labour force Must allow the port to evolve 30
Development Scenario Considerations: Accomodating trade type (1) Trade Requirements Containers Continuous linear quay Range of vessels sizes from feeders (50TEU) to ULCS (>12,500TEU) Manoeuvrable usually have bow thrusters Quick turnaround times needed <24hrs Usually use ship-to-shore cranes Quayside needs to efficiently move and stack/retrieve large numbers of containers General Cargo Always handled at the quayside Vessels typically 700dwt to 15,000dwt Variety of off loading equipment needed depending on cargo. Usually quayside crane and forklift. Can be ships gear. Solid bulks Handled at jetty or quayside, but loading/unloading system that can reach each hold Range in size from Handy Max to Very Large Bulk Carriers (over 180,000dwt). Largest (500,000dwt) draw 25m Loaded through loaders, unloaded through grabs or vacuum Stored/retrieved from stockpiles with conveyor 31
Development Scenario Considerations: Accomodating trade type (2) Trade Requirements Oils Handled at jetties Cargos piped to onshore storage facilities can be remote Commodity grades and viscosities variable dedicated pipelines or cleansing system. Can require heated pipes Gas Handled at jetties similar to oils LNG and LPG handled as liquids through pressurisation or cooling Hazardous materials requiring careful design and handling Chemicals Usually handled at jetties Typically limited draft Required large array of pipelines to handle multiple products Vessel usually loaded via flexible hose rather than loading arm Passengers Quayside with good landside connections to move passengers through quickly Ferries and Ro-Ro Vessels vary significantly Requires rapid unloading and storage (on/off terminal) of vehicles 32
Development Scenario Considerations: Other considerations Tugs, pilots and line boats Most major ports have compulsory pilotage Pilot boarding outside of port entrance or approach channel Tugs usually come along side and make fast outside of any breakwaters Line boats may be needed, more likely on jetties Safe mooring needs to be provided for tugs, line boats and pilots. 33
Development Scenario Considerations: Design Vessel Vessel forecast identified design vessel for each trade type Design vessel usually the largest likely, but not necessarily. Could be the least manoeuvrable Informs the design of dredged depths and berth length Design to give safe navigation and berthing for all likely vessels Unlikely that each container berth will need to accommodate the design vessel simultaneously design vessel often a rare visitor Design for a realistic vessel spectra 34
Development Scenario Considerations: Design Vessel Makassar Worked Example: Design Vessel Trade: Container Historic arrivals: typically 7,000 8,000 dwt (700-1000 TEU) The aging fleet means that these are likely to be replaced with steadily increasingly sized vessels. Likely that at the end of the design life, Panamax sized vessels could be calling at Makassar. Example design vessel CMA-CGM Georgia: LOA: 294m Beam: 32.2m Draft: 13.5m Capacity 5,085 TEU Likely to be calling toward the end of the design life. Berth structures to be designed to accommodate. Dredging could be phased over time. 35
Port Development Scenarios Segment 2: Development Scenario Considerations Establishing Baseline Conditions 13 May 2014 Formulation and Development of Port Development Scenarios

Development Scenario Considerations: Establishing physical baseline conditions Topographic and Bathymetric Determine dredge and reclamation volumes Inputs to hydrodynamic models Can use charts if current- fairsheets if possible Sidescan Should overlap 38
Development Scenario Considerations: Establishing physical baseline conditions Important to understand relationship between sea and land datums at the site: Land Datum: Constant level plane Sea Datum (CD): Not constant dependant on tidal range Difference between datums site specific Should be confirmed for each site Land Datum 39
Development Scenario Considerations: Establishing physical baseline conditions Metocean Wind and waves crane downtime, vessel downtime, berth alignment, cope levels, structural design, mooring loads, breakwaters Tides and Water levels surges, dredging and reclamation levels Currents berthing and mooring, tug requirements, sedimentation All need long sample times to cover cycles Wind for wave hindcasting needs high resolution sampling at regular intervals over a long period Good to collect all data at the same time 40

Port Development Scenarios Segment 3: Development Scenarios Port Approaches and Sizing Approaches, channels and basins 13 May 2014 Formulation and Development of Port Development Scenarios
Development Scenario Considerations: Establishing Navigational Areas - Channels Definitions: Approach channel links the berths of a port to the open sea outer channel exposed inner channel sheltered Channel and fairway a feature of a waterway that has enough width and depth to allow vessels to transit. Buoyed PIANC 121::2014 61
Development Scenario Considerations: Establishing Navigational Areas - Channels Objectives Minimise transit time to the port Minimise access restrictions Channel dimensions a function of: Size of vessel Manoeuvrability of vessels Winds Currents Choice of one-way or two-way is a economic one: Dredging costs (both capital and maintenance) Volume of traffic and likely demurrage costs The transit time and VTMS system Pilotage and tug availability 62
Development Scenario Considerations: Establishing Navigational Areas - Channels Rule of thumb: One-way container channel: 3.6-6 x beam (>5 x beam for oil and gas) Two-way channel: 6.2-9 x beam 63
Development Scenario Considerations: Establishing Navigational Areas - Channels Manoeuvring lane typically: 1.3 to 2.0 x Beam Sensitive to lateral wind areas: tankers in ballast, cruise and container Cross currents can cause yaw: 0.5 x Beam Caution with proximity to banks and other vessels can cause suction 2-way channel clearance >30m or largest B Widen channel at bends >10 o to at least 4 x Beam, can be more. Depth dependant Minimum curve radius >10 x greatest LOA Should not be designed for hard over rudder Should avoid vessel heading for quay during approach 64
Development Scenario Considerations: Establishing Navigational Areas - Depths Depth sufficient for safe manoeuvring at lowest water level allow for: Maximum loaded draft of the design vessel Water Level: Tide Surge note can be positive or negative Climate change more later Atmospheric pressure Vessel motion (roll, pitch, yaw and heave) Vessel trim during loading Squat Seabed characteristics Salinity Siltation Measurement errors Need not be the same as the berth box 65
Development Scenario Considerations: Establishing Navigational Areas - Depths Minimum gross UKC Rules of Thumb: Open Sea, High Speed ships, exposed to strong swells: Exposed channels, exposed to swell: Exposed manoeuvring and berthing area: Protected manoeuvring and berthing area: 30% of max draft. 25% of max draft. 20% of max draft. 10-15% of max draft. 66
Development Scenario Considerations: Establishing Navigational Areas - Depths Consider tidal restricted access: From PIANC report 121:2014 67
Development Scenario Considerations: Establishing Navigational Areas - Depths Tidal restricted access - The Port of Newcastle: 68
Development Scenario Considerations: Establishing Navigational Areas Swinging Usually in the basin, adjacent or as part of the channel Usual to make the turn during entry (i.e. under ballast) Typically on berth bow to sea Diameter will depend on: Vessel manoeuvrability Tug assistance Local conditions Rules of Thumb: Minimum for design 2 x LOA Vessel with Bow Thrusters With tug assistance Diameter as x of LOA 4 5 2.5 1.5 69
Development Scenario Considerations: Establishing Navigational Areas Channel Makassar Worked Example: Approach Channel Development Design Vessel: LOA: 294m Beam: 32.2m Draft: 13.5m Design Depth: Assume 85% load factor, so design draft = 0.85 x 13.5 = 11.5m Outside the reef assume 20% UKC = 11.5 x 1.2 = 13.8m Inside the manoeuvring area 10% UKC = 11.5 x 1.1 = 12.6m Adopt = 12.5m Design Width: Check narrowest point: 150m, depth 15m 150m = 4.7 x beam = OK Turning Area: 2.5 x LOA = 735m No constraints. 70
Development Scenario Considerations: Confirming Navigation Design Can be useful to confirming navigation through simulation as design progresses. Fast-time simulation cost effective Real-time simulation Part Mission good for option development Full Mission should be use to confirm final design and train pilots 71
Development Scenario Considerations: Example Fast-time simulation 30kn wind from NW 2.1kn current from SE Arrival: comfortable Departure: challenging 72
Development Scenario Considerations: Example Full-Mission Simulation 73
Port Development Scenarios Segment 3: Development Scenarios Port Approaches and Sizing Basin and Berth box 13 May 2014 Formulation and Development of Port Development Scenarios
Development Scenario Considerations: Basin and Berth Box The area adjacent to the berth Vessel will complete final berthing manoeuvres and sit along side throughout tidal cycle: Needs to accommodate vessel manoeuvring: Minimum width 1.25 x Vessel Beam Minimum length 1.25 x Vessel Length Depth need to accommodate vessel draft at all tides and loading states 75
Development Scenario Considerations: Selection of berth length Governed by ability to berth and un-berth design vessel Clearance typically multiple of largest vessel length: 0.1L for sheltered, 0.2L if exposed. Rough guide 30m for daylight berthing, 50m for night berthing Base total length on vessel size distribution Note does not apply to jetty berths which are vessel length specific 76
Development Scenario Considerations: Selection of berth length Time vessels spent queuing will be determined by berth availability Typically aim for waiting to service time ratios of: Bulk: <0.3 General Cargo: <0.2 Containers: <0.1 For containers: Assume continuous wharf length Initial estimate: Rule of Thumb: 1,000-1,400 TEU/m of quay Confirm acceptable waiting to service time ratio 77
Development Scenario Considerations: Determining Berth length Makassar Worked Example: Total Berth Length Trade forecast: 3M TEU per annum in 2036. Rough Estimate: Assume 1,200 TEU/m of quay = 2,500m of quay length required. 78
Port Development Scenarios Segment 3: Development Scenarios Port Approaches and Sizing Terminal and Yard Sizing 13 May 2014 Formulation and Development of Port Development Scenarios
Development Scenario Considerations: Establishing Yard Dimensions Typically about 500m 80
Development Scenario Considerations: Establishing Yard Dimensions - Apron Typically about 50m 81
Video: Loading and unloading container ships 82
Development Scenario Considerations: Establishing Yard Dimensions - Yard Demand based calculation based on (see earlier workshop): No of containers Dwell time Storage density Import, export, transhipment, Development Scenario based on benchmark: 40-50,000 TEU/ha/yr 83
Development Scenario Considerations: Determining Terminal Dimension 500m 130m 320m 50m Makassar Worked Example: Total Terminal Area Trade forecast: 3M TEU per annum. Rough Estimate: Assume 40,000 TEU/ha/yr = 75 ha of yard area required. Given quay length of 2,500m (see above) = 300 net yard depth 500m total terminal depth 50m apron 130m for back of port = 320m. OK 84

Development Scenario Considerations: Berth Availability and Calmness Vessel movement at berth can affect efficiency 3 translational movement: surge, sway, heave 3 rotational: roll, pitch, yaw 87
Development Scenario Considerations: Berth Availability and Calmness How far can a vessel move before loading/unloading is affected? Which direction of motion is likely to be worst for container loading/unloading? How many days per year should the berth be available? 88
Development Scenario Considerations: Berth Availability and Calmness Caused by: Passing vessels Tides Wind Waves Local waves fetch, duration limited. 5-10s. Swell waves propagated from distant storms. 8-20s. Long Waves low frequency/surfbeat/infragravity. Solitary or with wave group. 30s - >minutes 89
Development Scenario Considerations: Berth Availability and Calmness vertical motions Heave, roll, pitch: 15s natural oscillation swell waves PIANC Rpt 2012:115 recommends orientating berths into waves 90
Development Scenario Considerations: Berth Availability and Calmness horizontal motions Surge, sway, yaw 40-80s natural oscillation long periods waves Most critical whilst at berth 91
Development Scenario Considerations: Berth Availability and Calmness Acceptable movement depends on vessel type and size: PIANC 1995: 92
Development Scenario Considerations: Berth Availability and Calmness Acceptable vessel motions- current guidance (PIANC Rpt 2012-115): PIANC 2012-115: 93
Development Scenario Considerations: Berth Availability and Calmness Smaller Container vessels, PIANC 2012-115 recommends: 94
Development Scenario Considerations: Berth Availability and Calmness Assess by: Numerical modelling of wave agitation at the berth Mooring analysis Physical modelling Design out if necessary by: Selection of berth orientation usually within 30 o of prevailing wind direction Consider sheltering the berths either with reclamation or breakwaters most effective for local and swell waves Consider risk of long wave activity 95
Development Scenario Considerations: Berth Availability and Calmness Case Example: Port Kembla Port Kembla has a history of wave agitation in the outer harbour Photo taken during a storm in 1950 (modified from Figure 3 of Fitzpatrick and Sinclair, 1954) 96
