This paper is introduced by a brief explanation of the two-node mode of vibration of the hull girder causing the phenomena usually referred to as springing and whipping. The relation between the vibration level and the sea and navigation conditions is discussed and some trends in springing behaviour are identified. Because of the random nature of the waves, the springing vibration is also random. The statistical methods applied for description and prediction of springing are briefly outlined. The contribution of springing to the extreme longitudinal stresses and the resulting fatigue is also considered. Order from: BSRA as No. 49,087.
