Time domain comparison with experiments for ship motions and structural loads on a container ship in abnormal waves
The paper presents experimental results from model tests with a containership advancing in abnormal wave conditions and comparisons with numerical simulations. A nonlinear time domain method based on strip theory is used for the calculation of vertical ship responses induced by abnormal waves. This...

The paper presents experimental results from model tests with a containership advancing in abnormal wave conditions and comparisons with numerical simulations.

The time domain simulations are compared directly with experimental records from tests with a model of a container ship in deterministic waves for a range of Froude numbers.
