Long term automatic full-scale measurements of a container ship 'Beishu Maru' (24, 000 tDW) on the Pacific North West course have been operated for 52 months. For three item of pitching angle, rolling angle and wave bending stress of upper deck, the values of root mean square, maximum peak and minimum trough and zero-cross mean period for 30 minutes have been measured and, recorded on punch tape in every three hours. The environmental condition data by the favour of ship's crew are to be studied comparing with those ship's response.
In the first paper we have reported the statistical distribution of environmental conditions and corresponding operating conditions. In this second report, general frequency distributions cumulative probabilities and distributions of mean periods of ship's response have been studied. Intensive analysis of the data of rough sea conditions are to be reported in the next paper.
