Wave-induced vibrations in large ships have been a growing concern due to increased flexibility in hulls. Springing vibration, caused by unsteady pressure on the hull, can lead to fatigue issues in certain ship types. To predict and address this, researchers compared two strip theories and used a hydroelastic strip theory with a hydrodynamic pressure solution to calculate vertical wave forces on the hull. They found that considering diffraction wave pressure is crucial for accurate springing prediction in ship design.
