| Description: |
A standing person is exposed to dynamic motions in daily tasks. These motions may be experienced whilst travelling on various modes of transport such as trains, buses or ships, or whilst standing on a floating structure such as a floating pontoon or platform. Pontoons exposed to waves move dynamically. There is limited useful data (prototype nor model) on the dynamic responses (displacement, velocity and acceleration) of floating pontoons to wave excitation. Similarly, there are no design codes for floating pontoons specifying the allowable dynamic responses in order to maintain postural stability. This paper first presents a summary of the current understanding of postural stability and reviews where postural stability is considered in design. The summarised information is categorised into a set of motion limit criteria that are compared with new experimental results obtained during the modelling of the dynamic responses of a floating pontoon. Based on initial test results, the accelerations recorded for a floating pontoon under regular wave motion exceed the safe motion limit criteria identified for other floating bodies. In some of the tested scenarios the recorded accelerations were up to six times greater than the safe motion limits. This exceedance could pose a risk to the safety of people using floating pontoon structures. Further testing is needed to determine a set of design criteria for floating pontoons that meet safe motion limits in order to better design for public comfort and safety. |
