Abstract

Attaching a spoiler on the top of pipeline is a new method to enhance self-burial of pipeline. The pipeline state in Hangzhou Bay with spoiler was investigated in this study in order to understand the mechanism of spoiler. Based on the route survey data combined with the seabed and hydrodynamic characteristics, the effect of spoiler on self-burial of pipeline was discussed. The survey data illustrate that the percentage of buried pipeline increased from 50% in 2005 to over 80% in 2013, and the average buried depth increased to 2.60 m, which shows that this self-burial method is applicable in this region. While some sections of the pipeline where the flow direction is parallel to the route or on strong anti-erosion river bed are still exposed on the seabed due to the ineffectiveness of spoiler.
