Abstract: Ballast pipeline is one of the most important systems of ship hull. If each ballast cell unit is not well controlled or the ballast cell unit cannot be pressed and unloaded,the marine mobile facilities will be in serious safety hazard. In order to improve the design of FRP ballast pipeline of FPSO,by changing the design space layout and adding related equipment,the autonomous ballast function of the fore ballast tank except the left and right ballast tanks on the hull is realized and the research and analysis is carried out to facilitate the inspection,maintenance and repair of the pipeline. Based on the example,the feasibility study on the application of domestic FRP pipe in marine ballast piping system is put forward.
