Abstract
In this paper, the global motions and wave loads on a large bow-flare ship in oblique regular waves considering hydroelastic effects are studied both numerically and experimentally. Numerical simulations of the ship's asymmetrical motions and loads in waves are conducted using a CFD-FEM two-way coupled method. The segmented model tank test is also conducted by using a hybrid structural backbone beam to measure both the sectional vertical bending moment and torsional moment. The numerical results are verified and validated by analyzing the ship modal behaviour, roll free decay curve, motions and loads and comparing with the experiment results. The influence of wave heading angle, wave length, wave height and ship speed on the wave loads including sectional bending moment and torsion moment are comprehensively studied with the numerical and experimental results. The relationship among vertical bending moment, horizontal bending moment and torsion moment is also discussed.
