This paper describes a method of quantifying the impact effects throughout an offshore platform crane structure when lifting from supply boats in various sea states. The method employs Multi-Degree of Freedom dynamic analysis techniques. It is particularly relevant to cranes mounted on high (flexible) pedestals and in addition to providing a method for rating the cranes, it can be used to generate fatigue spectra for the various crane components. An earlier published method for determining the impact effects is also described. This method ignored the effect of the masses in the crane structure and some comparison of results of the two methods is included. (Se)
