In the past, construction operations under screening conditions have also gradually been replaced by unprotected or undercover conditions. Obviously, unprotected sea areas are often affected by the waves and can not be operated, thus reducing the number of days of operation. Therefore, the wave height of the construction area is the preparation of operational plans, indeed
