Abstract
A rigid module rigid connector(RMRC) model is used to study the dynamic characteristics of connectors of modular offshore platform. It is assumed that the modular offshore platform is a whole structure and the connector loads are simplied as the corresponding section loads is deduced using the Three-Dimensional Potential Theory by means of the assumption—High Encounter Frequency with Low Sailing Speed. 2 sea state cases, 4 structure sizes, and 7 wave angle connectors are calculated gaining the dynamic responses and sea states of connectors,and the regularity and relationship between configuration sizes and wave angles which is useful to design and utilization of connectors.
