Abstract

This work presents a review of data from the literature related to abnormal waves, also known as rogue waves or freak waves, due to their destructive effects on ships, on marine structures and activities. There are considered abnormal waves, the waves with the height exceeding at least twice the significant wave height for a given sea state.
The most recent researches have shown that extreme waves with crest to trough heights of 20 m until 30 m occur more frequently nowadays. These types of waves suddenly strike the ship, making the situation particularly dangerous during the storm conditions if the ship is in a head sea and suddenly goes into an abnormal roll.
Therefore, it is imposed that the current design criteria to generally consider the significant wave heights of 20 m till 30 m. Also, the dynamic forces of the waves impact should be included in the structural analysis of the ship.
