Abstract

The causes and mechanism inducing the breakdown and follow up displacement of an outflow pipeline off Penghu Islands, Taiwan was investigated. Based on the information illustrated in the high resolution side-scan sonar imagery, it was concluded that the breakdown of the pipeline was initiated by a large external pulling force. In addition, this pulling force dragged the breakdown pipeline westward with a net displacement of about 100 m. After the pulling force disappeared, environmental forces such as tidal currents interacted with the floating section of the breakdown pipeline caused a further and complex displacement pattern of the breakdown pipeline especially in the portion near the outlet. At the moment of this forensic investigation, the overall appearance of the breakdown pipeline illustrated an irregularly-shaped circle. Further displacement of the breakdown pipeline in accordance with sea states is highly expected.
