Abstract

This paper aims to give a new perspective on possible criteria for the pipeline and cable flotation phenomenon. Laboratory flotation and pullout tests have been conducted in high moisture content kaolin clay using a model pipeline or cable analogue of 63mm diameter installed at different embedment depths. Uncertainty over the definition of "flotation" has led to comparison of data from previous studies and those obtained from the pull-out tests described herein. Different definitions of flotation may lead to a significant increase in the magnitude of available resistance used in design which can directly affect the commercial choices made for commercial pipelines and cables (e.g. coating type and thickness and minimum burial depth).
