A comprehensive study on ship motion and load responses in short-crested irregular waves

International Journal of Naval Architecture and Ocean Engineering, 2019
Wave-induced ship motion and load responses are usually investigated on the assumption that the incident waves are long-crested. The realistic sea waves are however short-crested irregular waves.

EXPERIMENTAL STUDY OF TWO LARGE-SCALE MODELS’ SEAKEEPING PERFORMANCE IN COASTAL WAVES

Brodogradnja, 2015
Actual sea waves and vessel motion are an unsteady nonlinear random process. The currently adopted test to simulate wave impact of vessel models in tank can't fully reveal the impact of real sea waves on vessel swing motion.

Development of A Hull Motion Measurement System for Evaluating the Seakeeping Performance of a ship [PDF]

, 2006
In order to evaluate the seakeeping performance at sea and the safety of mooring on berthing, it is necessary that the ship dynamic motion induced wave and wind should be measured in real time domain for the validity of theoretical evaluation method such
