Description
Summary:Experimental investigation was carried out in a wave flume to study the stability of marine pipelines on mobile and liquefied seabed. A wide range of different pipeline specific gravities and wave condition were examined. The results showed that for the given soil the seabed response is governed mainly by liquefaction and the pipeline behaviour on unstable seabed is strongly dependent on its specific gravity.
