Safety

Community concerns centred around the length ofthe cable ferry crossing and the operatingenvironment

BCFS has conducted further, extensive dynamicanalysis of the integrated cable ferry system,including:

~ validation of environmental conditions and imposed loads, withextreme values of local wind/wave data used in the analysis (RoddanEngineering Ltd)

~ hydrodynamic development & testing of ferry (Oceanic)

~ cable load analysis and dynamic interaction of ferry and berth/s(Dynamic Systems Analysis)

~ determination of operational limits, cable specification and safetyfactors using extreme conditions (E.Y.E. Marine Consultants)

Safety

Conclusions from Dynamic EngineeringAnalysis:~ The limiting Safety Factor (FS) for the cable system wasderived from Offshore ocean regulations, and based on theextreme dynamic load imposed on the system

~ Cable size under consideration is 1-5/8" dia: resultant FS

would be 2.06, based on minimum breaking force of the cable.Thus, minimum breaking force of cable under extreme dynamicconditions would be more than double the worst operationalload on the system (all environmental effects modelled)

~ The equivalent FS in the static load condition (pre-tensioned)= 6.0

~ Cable drift at mid-channel distance ~ 92m in the worst

operating condition, equating to a 10% offset over the cablelength

Safety

Navigation/Marine Traffic:

~ The cable ferry does not present a navigation hazard. TC hasapproved the Project under the Navigable Waters ProtectionAct

~ Standard Operating Procedures (SOPs) will be in place andwe will properly train the crew to safely operate the vessel

~ Cable Ferry will have an emergency boat in place and it willbe able to be launched and deployed in a similar fashion that iscurrently done on Quinitsa


6/126

Alternative Service Provider

BCFS conducted a formal RFP process to determineif another operator, under contract to BCFS, could

provide the cable ferry service to a similar level ofsafety and quality, at a lower cost

~ Conclusion:

- Evaluation did not support the case to move forwardwith an Alternative Service Provider for the Design, Build,

Acquire and Operate the cable ferry system

- There will be no further Operate OnlyRFP

BCFS will design, build and operate the Cable Ferry

System


7/127

Home Port

The Denman/Hornby community, together withemployees and BCFMWU, expressed concern aboutthe possibility of relocating the home port toBuckley Bay

~ Of particular concern was the availability and responsivenessto emergency/after hours call-out

~ Concern was also raised about the impact to jobs onDenman

BCFS response:~ The cable ferry will be home-ported at DenmanWest, docking overnight and will continue to be

crewed from Denman


8/128

Operational Availability

Service levels will be maintained, satisfying CFSC requirementsand similar to the existing ferry:

~ 99.96% operational availability without restrictions (based on

worst vessel roll motion in sustained wind speeds up to 38 knots,mid-channel, with corresponding wave heights)

5 sailings/year (0.04%) on average may be affected

3 year average weather-related cancellation rate for all island (non-Northern) routes is 0.34%

~ restricted/emergency operations would continue up to 55 knots(sustained wind speed, mid-channel, with corresponding maximumwave height) corresponding to the current limit on service.

Vessel back-up/relief support will be put in place according tocircumstances, consistent with current BCFS practice

~ Ramps will be on the shore terminals, increasing flexibility for relief

service.


9/129

Crew Complement

Cable ferries generally operate with a crew of 1 or 2

BCFS conducted a risk assessment around both design and

operational criteria; analysis indicates that the cable ferrycould be safely and efficiently operated by a crew of 3

~ Transport Canada will determine the final crew size

~ BCFS will work with employees and BCFMWU on this matter

~ Changes in terminal manning are not anticipated


10/1210

IMPACT ON FARES

Economic advantage over conventional service is substantial

~ Significantly reduces capital spending

~ Operating costs are significantly less

- assumes crew reduction of 3

- assumes 45% of current fuel consumption

- a simpler vessel will require less repair & maintenance

~ Savings will help to reduce pressure on future fare increases, for

the benefit of all users

~ Forecast savings of $80M over the 40 year life of the cable ferry

~ That equates to a Net Present Value (NPV) of $19M


11/1211

KEY FACTS

BCFS Board of Directors has approved the Cable FerryProject

~ BCFS will proceed with its plan to introduce Cable FerryService between Buckley Bay & Denman Island (Rte 21)

~ BCFS will design, build and operate the Cable FerrySystem

~ There will be no Alternative Service Provider

~ The Cable Ferry will be home ported at Denman


12/1212

Key Milestones

Next steps:

~ Commence detailed design & engineering

development of the integrated cable ferry system

~ Contract awards for both vessel and terminalconstruction anticipated summer 2013

Entry-into-service estimated October 2014

YOUR INSURANCE

~ BC Ferries will keep Quinitsa in place until cableferry is fully tested and proven
