Evaluation of rogue wave induced loads using 2D hydroelasticity analysis
Evaluation of wave-induced motions, accelerations and loads are important for predicting the performance of ships in waves and assessing their strength. Rogue waves are a phenomenon that has become an important issue recently due to a number of key incidents and/or loss of life. Two-dimensional (2D) hydroelasticity analysis has been extensively applied to predict wave-induced motions and loads in regular and long-crested irregular waves, including severe weather conditions. This paper focuses on the evaluation of symmetric motions (i.e. motions and distortions in the vertical plane) and global wave-induced loads for a Leander class frigate in head irregular and rogue waves using a 2D hydroelasticity analysis. Predicted motions are compared with test measurements from a rigid model in head irregular and rogue waves. Two options for generating rogue waves, namely optimizsation and NewWave approaches, are investigated. Comparisons are made between irregular and rogue waves. The effects of forward speed and slamming are discussed.

Abstract
Evaluation of wave-induced motions, accelerations and loads are important for predicting the performance of ships in waves and assessing their strength. Rogue waves are a phenomenon that has become an important issue recently due to a number of key incidents and/or loss of life. Two-dimensional (2D) hydroelasticity analysis has been extensively applied to predict wave-induced motions and loads in regular and long-crested irregular waves, including severe weather conditions. This paper focuses on the evaluation of symmetric motions (i.e. motions and distortions in the vertical plane) and global wave-induced loads for a Leander class frigate in head irregular and rogue waves using a 2D hydroelasticity analysis. Predicted motions are compared with test measurements from a rigid model in head irregular and rogue waves. Two options for generating rogue waves, namely optimizsation and NewWave approaches, are investigated. Comparisons are made between irregular and rogue waves. The effects of forward speed and slamming are discussed.
