Motivation for New 3rd SeaBus
– In August 2006, TransLink issued an RFP in support of their procurement of
a Third SeaBus.
– The need for a new vessel was based on:
• Increasing ridership
• Fits within regional transportation initiative (Gateway Project)
• Fits within overall service goals (7 min. service/ 7 days per week)
• 2010 Olympics
Q: Why not repeat?

3rd SeaBus
A1: Owner’s Requirements
“Customer convenience”
•Potential for improvement?
•Yes
“Compatibility with existing
infrastructure”
•Potential for improvement?
•No
“Lowest life cycle costs”
•Potential for improvement?
•Probably
“Compatibility with future upgrades for
SeaBus I and II”
•Potential for improvement?
•Not Really
“Minimize environmental impacts”
•Potential for improvement?
•Yes
A2: Regulations
• New Regulations and/ or Regulations Applied Anew (no exemptions to
be carried over)
– TP 2237 Equivalent Standards for Fire Protection
– TP 439E Structural Fire Protection Standards: Testing and Approval Procedures
– TP 10943 Passenger Vessel Operations and Damaged Stability Standards (Nonconvention vessels) (2007)
– Canada Shipping Act 2001 “Marine Personnel Regulations”
– Canada Shipping Act 2001 "Life Saving Equipment Regulations"
– Canada Shipping Act 2001 “Regulations for the Prevention of Pollution from Ships
and for Dangerous Chemicals”
– TP 3313 Collision Regulations
– Tonnage Regulations
A3: Operator’s Experience
• Wheelhouse
• HVAC
• Passenger Cabin
• Machinery space access
• Noise and vibration

Preliminary Lines with Michlet
• Michlet – a open source freeware design tool
• Provides numerical solutions to Michell’s wave equation
• Calculate resistance, wave elevation patterns
• Allows for parametric variation of hull shape
• Includes an optimization module using the ALife technique
• Two components of the program are
• Michlet Wave Equation
• Wigley Hull Form
• All credits to Department of Mathematics at the University of Adelaide
Michell’s Wave Equation
– The means to evaluation hull performance:
Wigley Form
– The means to generate similar, but randomly different hull forms:
f (a, b, c)
Wigley Form
f (0.5,0.0,0.5)
f (0.5,0.5,0.5) f (0.5,1.0,0.5)
