The research results show the riser's weld fatigue life by RMFE system, based on the “strain reconstruction”, aligns with the results from ABAQUS and FEM theory, with most errors within 3% and the maximum error not exceeding 16%. Furthermore, smaller mesh sizes in the RMFE system can reduce calculation errors but increase computation time.

Using a two-dimensional flume developed in OpenFOAM, simulations of freak waves and wave-structure interactions were conducted. The protective capabilities of the combined breakwater were assessed by analyzing the changes in force on the bridges, and the wave dissipation mechanisms were explored through wavelet transform results and flow field analysis. The study reveals that the combined breakwater effectively reduces wave loads compared to conventional submerged breakwaters, due to the conversion of high-frequency waves into low-frequency waves facilitated by the floating structure. This interaction, along with the submerged structure, enhances the overall stability and service life of the breakwater. The stability and load reduction performance are influenced by the initial draft and length-to-height ratio of the floating structure, with optimal performance achieved at specific configurations.

Given the inherently slow growth of corals, it is challenging to empirically or experimentally determine the optimal hydrological environment conditions involved in reef restoration. This study introduces a three-dimensional numerical wave flume to precisely simulate the complex interactions of artificial coral reefs with wave forces at various developmental stages. This study reveals that the efficacy of the wave-attenuating effect is heavily influenced by factors such as water depth and reef porosity. Shallow water depths notably enhance wave attenuation, stimulating coral growth by promoting dynamic water mixing. Coral reefs with porosity above 0.75 exhibit changes in transmission coefficient but have minor effects on coral-wave interactions. The optimal water depth for a successful transplant should range between 1.5 and 2.5 times the height of the reef platform. An optimal distribution of corals across the shelf, occupying 25–30% of the total volume, is crucial for effective transplantation.
