Ferry Boarding Facilities

1.1
This Standard specifies requirements that are consistent with current practice for the design of new, or the replacement of existing, boarding facilities, including

(a) vehicular and foot passenger ramps and support structures;

(b) access interfaces between shore/ramp and ramp/vessel; and

(c) operating systems.

Note: Existing installations are exempt from this Standard until major structural, mechanical, or electrical modifications are undertaken.

1.2
The provisions of this Standard apply to single-level and multilevel boarding facility ramps with a shore- based hinged connection and seaward end conditions in accordance with one of the following :

(a) the seaward end of the ramp is supported by shore-connected structures, and transition to the ferry (vessel) decks is achieved by an apron attached to either the vessel or the ramp;

(b) the seaward end of the ramp is supported by the vessel for traffic loading and off-loading periods. Support at other times is provided by fixed or floating shore-connected structures; or

(c) the seaward end of the ramp is supported by a floating structure at all times.

Note: Appendices A and B contain information and illustrations on geometry and ramp supporting systems.

1.3
This Standard establishes specific requirements for two operating conditions:

(a) Condition 3, in which the ramp is adjusted only when completely cleared of vehicular or pedestrian traffic; and

(b) Condition 33, in which the ramp is adjusted with full live load.

1.4
Vehicular design loads are based on highway traffic loadings listed in CSA Standard CAN/CSA-S6 and on provincial highway loading limits. For vehicles to which these Standards do not apply, the design principles may be applied to the actual vehicle loading.

1.5
This Standard does not include provisions for the design of ancillary wharf, trestle, or berthing structures.

1.6
This Standard does not apply to the design of railroad boarding ramps.

1.7
The provisions of this Standard are not intended to preclude the advent or introduction of new technology, processes, or materials that conform to sound design principles and are not covered in this Standard.

1.8
The requirements of this Standard assume that the provisions set out in CSA Standards CAN/CSA-S826.2, CAN/CSA-S826.3, and CAN/CSA-S826.4 will be applied.

1.9
The values given in SI (metric) units are the standard. The values given in parentheses are for information only and are used mainl y to identify nominally sized components.
