A comparison study on the hydrodynamic performance of a buoyancy-distributed floating foundation in regular waves

The manufacturing and assembly costs have a great significance in floating foundations of offshore structures. This paper presents a novel buoyancy-distributed floating foundation (BDFF) based on modular design and validates its high hydrodynamic performance. A centralized ballast platform with a single-point mooring system and a distributed ballast platform with a multi-mooring system are designed for comparison. A series of tests with scaled models and numerical simulation work were conducted in regular waves. There is good agreement in the response amplitude operators (RAOs) for the experiments and the simulation with a bit of over-prediction. Additionally, the influence of wave frequencies and wave heights on the BDFF is also investigated. It is found that the model with a multi-point mooring system gives a moderate response and can be regarded as a linear system, while the model with a single-point mooring system has a large responsivity for high frequencies.
