Ocean environment loads consist of the wind force, sea wave force etc. Sea wave force not only has randomness, but also has fuzziness. Hence the non-deterministic description of wave environment must be carried out, in designing of an offshore structure or evaluation of the safety of offshore structure members in service. In order to consider the randomness of sea wave, the wind speed single parameter sea wave spectrum is proposed in the paper. And a new fuzzy grading statistic method for considering fuzziness of sea wave height H and period T is given in this paper. The principle and process of calculating fuzzy random sea wave spectrum will be published lastly.
