Classification and Application of Offshore Pipeline Trenching Technology and Equipment

Abstract

Abstract:

To assure the stability of offshore pipeline and avoid hazard from the external environment, normally the pipelines are protected by trenching in the shallow sea. The pipeline trenching methods and installation tools are presented, and their function and characteristics are described. Furthermore, the selection of trenching methods and tools are studied. This research can provide the solution to trenching method of offshore burial pipeline in the earlier stage of engineering design.

Key words: offshore pipeline, trenching technology, installation tools, soil
