An investigation into the response of a modular pontoon system to wave loading

Abstract

This project involves investigating the response of a modular pontoon system when put under wave loading. In addition, this report also hopes to establish a point at which the movement of a pontoon due to waves will cause the pontoon to be considered unsuitable for use. This research draws upon previous work conducted within the field and expands upon it using physical modelling. In this case the modelling comprises of a modular pontoon being subjected to waves with a range of frequencies and amplitudes. Thorough analysis of results obtained from this determined that under higher frequency waves the movement response of a modular pontoon is less than that when under low frequency waves. In addition, a recommended value for the slope of a modular pontoon of 1 in 7.5m was defined as the steepest allowable gradient for a modular pontoon before it should be considered unsafe for use
