The application of CFD is expanding in the analysis of hydrodynamicloads in ships and offshore structures. However, CFD results in waveimpact problems are still difficult to be sure that it has high accuracy.This is because researchers apply CFD analysis according to differentlevels of techniques and procedures. In order to have reliable CFDresults on wave impact problems, a proper standard of CFD analysisneeds to be prepared. For this purpose, it is important to verify the CFDresults with reliable experimental results. It is motivated to carry out themodel test of slamming and green water load on FPSO for thevalidation of CFD results. The present study considers slamming andgreen water loads acting FPSO based on the model test. A 1/50-scalemodel test was performed on the ocean basin of KRISO. The slammingload acting on the bow of FPSO was measured under breaking wavesand the slamming impact was recorded using a high-speed camera. Inorder to see the variability of the slamming load, it was repeated 20times for each condition. The green water load on the side wall ofFPSO was measured in regular and irregular waves. The measuredslamming and green water loads are presented and those characteristicsare discussed.
