NON-NORMALITY OF PROBABILITY DENSITY FUNCTION OF TOTAL SECOND ORDER RESPONSES OF MOORED VESSELS IN RANDOM SEAS

This paper deals with the statistical estimation of total second order responses, including slow drift oscillation, of a moored floating offshore structure in random seas. The aspects covered in the studies described included: stochastic interference between wave frequency response and slow drift oscillation; the development of an extended theory of probability density functions for instantaneous response and its maxima; and the non-normality of the total second order motion. It was found that the interference between the first and second order responses played an important role in relation to the probability density and the extreme value of the total response.
