Modular floating structures are normally made up of modules which are connected using network of connectors. These connectors are prone to heavy load due to facing the open sea wave. Previous studies have examined simple module configuration such as two rectangular form arranged linearly or three or seven hexagonal form arranged in an oblique pattern experimentally or using CFD and FE packages. Two challenges persist afterward; firstly, on applying the current findings to topology made up of a bigger number of modules and secondly on estimating the axial load values of connector at the preliminary design stage. This study developed an approximation method of axial force at the connector based on basic module configuration of hexagonal modular floating structure and axial load values determined by earlier studies. Four approximation methods vary with number of modules, arrangement and connectors facing 900 wave direction were proposed. Early analysis of the proposed method revealed that the axial force of the hexagonal modular connector is affected by the overall structure type and configuration such that hexagonal module-to-module connection requires higher axial load as compared to hexagonal modular cluster-to-cluster linkage due to load distribution amongst the connectors.
