Semi-submersible platform is a new type of deepwater floating platform, which can be used for oil and gas exploration, development and production in the South China Sea. Steel catenary risers (SCRs) are widely used in deepwater applications due to the relatively simple structure, economy and reliability. The strength of SCR is usually influenced by environmental load and platform movement. Whether the strength meets the requirements is related to the production safety of the platform, so the study of riser strength is crucial. We mainly introduce the layout and configuration of riser, as well as the design method and key technologies of riser, and study SCR strength for the application of SCR to semisubmersible platform in the South China Sea. The strength analysis results of 18-inch riser are given as an example, which provides a good reference for the engineering design of riser.
