Flexible jumpers connecting the vessel to the STLP effec鄄 tively isolates the dynamic vessel motions from the rigid risers. Though the decoupled effect from flex鄄 ible jumpers was confirmed to some extent, many problems still remain on the detailed influence of flexible jumpers. This paper details the results of a study to investigate the effects of flexible jumpers on the global behavior of the rigid riser based on STLP concept. A general description of STLP/Flex鄄 ible jumper configuration as well as the numerical modeling methodology is introduced. The compar鄄 ’ ison results, such as riser global response, riser interference, riser s strength, buckling as well as fatigue performance, in relation to STLP with and without flexible jumpers under the excitations of currents, random waves and vessel motions are
