The paper presents results from the analysis of data collected during six of the worst storms recorded in the last five years at the Total Oil Marine North Alwyn platform in the northern North Sea. During three of these storms significant damage occurred to offshore installations in the North Sea or West of Shetland. This paper concentrates on individual wave characteristics. It considers the joint probability of waveheight and period and, in more detail, the joint probability of waveheight and steepness for which the suitability of various models has been examined. The horizontal and vertical asymmetry of individual storm waves is presented graphically and simple empirical relationships presented for the relationship between crest height and waveheight. The profiles and the characteristics of the three largest waves in each storm are presented and discussed.
