Presentation Overview Learning objectives Ferry facilities and service Vessels Ferry terminals Operations Capacity considerations
Learning Objectives • Gain an understanding of the wide variety of vessels, service types, and conditions which influence ferry service • Unlike other transit services, ferry services tend to vary widely and have little in common with each other • Presentation of vessel access considerations and typical terminal configurations • Become familiar with factors affecting ferry capacity: • Berth capacity • Dock capacity • Vessel passenger capacity
Changes from the 2nd Edition • Re-organization of chapter for clarity • Updated content • Removal of material unnecessarily specific to certain systems • Generalization of other content to increase applicability • Discussion of maritime security (MARSEC) • Purpose is to promote a framework for understanding ferry operations and capacity instead of specific approaches for certain system types • New spreadsheet tool for helping evaluate ferry transit capacity
Ferry Facilitiesand Service Colman Dock, Seattle
Ferry Facilities and Service Boston • Ferries provide a significant transit element in many cities: • New York • San Francisco • Seattle • Vancouver, BC • Boston • Also in smaller communities: • Nantucket – Martha’s Vineyard • Victoria, BC
Many Systems Go Unnoticed Ferry on Puget Sound, WA • Washington has: • Eight publicly owned ferry operators with 16 routes • At least three privately operated systems • Several tourist systems (excursions)
Distinct Types of Ferry Service Water taxi, Baltimore Mixed auto–passenger Passenger-only Water taxies
Route Types Ferry services crossing San Francisco Bay Crossing bodies of water Island service Parallel to shoreline Two-stop routes Multi-stop routes
Factors Unique to Ferry Service Harbor ferries, Copenhagen • Tidal influence (ranges from minimal to 40 feet) • Water body and shoreline • Harbor congestion • Weather (fog, wind) • Vessels are usually one or few of a kind • Berthing requirements vary byvessel class • Length, width, freeboard,door locations • Island service requirements • Emergency, commercial,reservations, other
Factors Unique to Ferry Service (cont’d.) • Most trips are multimodal • System lack of spare vessels • Operation by non-traditional transit providers • Regulatory environment (US Coast Guard) • Certificates of Inspection – Capacity • Crew size (dispatch problems) • Security requirements • MARSEC Levels 1, 2, and 3
Ferry Vessels Staten Island Ferry, New York
Factors Determining Vessel Type • Type of service • Auto–passenger, passenger-only, water taxi • Required speed • Conventional or high-speed • Environmental factors • Seas, reliability • Operational costs • Speed-dependent
Vessel Types Catamaran, Sydney, Australia Monohull Catamarans Small Waterplane Area Twin Hull (SWATH) Hydrofoils Surface effect ships Hovercraft
Ferry Terminals Ferry Building dock, San Francisco
Factors Influencing Ferry Terminal Siting Ferry terminal, Sidney, British Columbia • Difficult shoreline issues – residential, downtown, industrial • Public access – views – aesthetics • Shoreline conditions • Water depth • Currents • Fetch & breakwaters • Marine traffic • Marine life
Terminal Elements SeaBus Terminal, North Vancouver, British Columbia • Street access • Terminal building • Lobby (open queuing area) • Ticketing (fare sales) • Control (collection, passenger count, security) • Secure holding (security, pre-load) • Boarding control
Terminal Elements (cont’d.) Circular Quay, Sydney, Australia • Vessel access • Pier (deep water) • Berth (mooring) • Ramp (elevation) • Gangway (access)
Example Terminal Configuration Boarding Control Berths Ticket Collection Security Passenger Count Secure Holding Gangways Ticketing Lobby Street Access Terminal Building Ramp Pier
Issues with Multiple Routes at a Single Terminal Boarding Control Berths Ticket Collection Security Passenger Count Secure Holding Gangways Ticketing Lobby Street Access Terminal Building Ramp Pier • Passenger control and separation by route • Simultaneous vessel landings can occur • Embarkation and disembarkation conflicts

Operations Active Pass, British Columbia
Routes and Crossing Capacity Multi-stop ferry service, Brisbane, Australia • Multi-stop routes: • Passengers may or may not disembark at a stop • Passenger count is difficult to maintain • First-in first-out pre-staging passengers is difficult • Crossing between two points: • All passengers disembark at each stop
Capacity Island ferry service, Fur, Denmark
Berth Capacity • Berth capacity: Arrival service time • Vessel clearance time • Maneuver • Tie up • Gangway placement • Disembarking time • Passenger volume – bottleneck location • Passenger walking times (from vessel to holding area access)
Berth Capacity (cont’d.) • Berth capacity: Departure service time • Embarking time • Passenger volume – bottleneck location • Passenger walking times (from holding area to vessel) • Vessel clearance time • Gangway removal • Tie up • Maneuver • Total of departure service time, arrival service time, and an operating margin to account for delays gives the minimum service time per vessel • These times will be different for different vessels using a berth, and will vary by time of day with passenger volumes • These service times determine the maximum number of vessels that can be scheduled to use a berth during an hour
Notes on Berth Capacity (cont’d.) • Simultaneous disembarking and embarking • May not be viable due to security requirements • Difficult at best—no control in a hazardous area • Passenger load control is difficult • Automobile embarking and disembarking • Procedure included in TCQSM • Not addressed further in this presentation • Schedule float/operating margin • Additional time for consideration of uncertain or extreme conditions
Dock and Route Capacity • Dock capacity • Sum of individual berth capacities • Number of vessels serving berth in an hour • Passenger capacity of vessel(s) serving berth (not all vessels using a given berth may be identical) • Vessel passenger capacities will vary by amount of crew provided • Route/crossing capacity • Vessel frequency • Vessel passenger capacity • Peak hour factor (PHF) • Accounts for fluctuations in demand during the analysis hour • Not all offered capacity will be able to be used, except under a reservation system, if pass-ups are not to occur • Capacity = (frequency) ×(weighted average vessel passenger capacity) ×(PHF)
