An Example of Successful Design for Pipeline in Concentrated Waters Region——The design of Jing-Wu Ethene Pipeline

Crossing over the concentrated waters region in the Yangtze River delda, being adjacent to Shanghai where exist dense population and buildings, the Jingshan - Wujing ethene pipeline needs critical design and construction. Despite of the complexities and difficulties, the desigh is successful and experiences have been obtained for the pipeline construction in such regions. The main features and experiences in the design are introduced and four suggestions are put forward in the paper.
