The connector loads of a 3-module VLFS (Very Large Floating Structure) deployed in the shallow water areas have been investigated by experimental and numerical methods. For the numerical method, a simplified analysis procedure has been built based on 3D hydroelasticity theory and RMFC (Rigid Module Flexible Connector) model, and the effect of the uneven seabed can be included in this procedure. The model tests of the 3-module VLFS considering the complicated seabed topography and wave environment have been finished. Some key technologies for the model tests have been solved, such as the simulations of the complicated seabed topography and the connector model. A lot of the first-hand model test results have been discussed and compared with the numerical results. Some useful conclusions were obtained, which can provide reference basis for the preliminary and conceptual design of VLFS and its connectors.
