Moving ocean platforms, such as ship, fishing vessels and offshore platforms etc, suffer seriously from sea loads as wind, wave, currents and other environmental factors. Platforms’ motions induced from various sea loads have significant effects on crews aboard. Severe motions of the platform can make crew lose balance or cause motion induced interruptions (MIIs). This paper studies postural stability of crews on moving platforms based on Chinese anthropometric standards. The relationships between height of center of mass (COM), moment of inertia and human’s height, mass of human body are analysed. The postural stability indicator, tipping coefficient is obtained of human body on moving platform by applying Chinese anthropometric standards. Then the stability domains of human bodies with translational is derived considering the physical parameters of Chinese adults. The work can be helpful for estimation of MII probability and safety of crews on moving ocean platform.
