Offshore ocean station is an isolated building in the sea with rough condition. Pile wharf structure is a very suitable structure form to offshore ocean station. This paper discusses the structural type selection, structure design, structure calculation, construction, etc. based on Lianyungang harbor 300 000DWT waterway engineering Xuwei ocean station project which is already under operation. The pile wharf of ocean station design and construction are summarized and analyzed. It may serve as reference for the research and construction of offshore ocean station project.
