Section 1 General

Parent topic: Chapter 5 Bridge/Vehicle Ramp Strength

1.1 Application

1.1.1 This Chapter provides the strength requirements for bridges and ramps, used for the carriage of vehicles between ship and shore, and their support structures.

1.1.2 The bridges and ramps may span between:

  1. The quay-side and a pontoon.

  2. The quay-side and a non-buoyant means of support (e.g. gantry).

  3. A pontoon and the berthed ship.

  4. The quay-side and the berthed ship, or,

may be entirely supported by a pontoon or two non-buoyant supports.

1.2 Objective

1.2.1 The scantlings and supporting arrangements are to be consistent with the method of support, the environmental conditions prevailing at the operating location, the berthing conditions and the specified vehicle loading data.

1.2.2 Bridges, ramps and their bearings are to be suitably designed to accommodate, where applicable, the effects of a static support at one end and a dynamic support at the other.

1.2.3 Consideration is to be given to the proposed frequency of use, including the frequency of ferry berthings and the number of vehicles using the bridges and ramps.

1.3 Basis of structural design

1.3.1 The adequacy of the structural components in this chapter is assessed on the basis of an allowable stress and factored load approach.
