Between 1985 and 1992, at the NUTEC training facility in Bergen training launches at heights of both 28 meters and 12.5 meters took place. During this period sixteen injuries to personnel were sustained. It is not recorded if all the injuries were associated with a particular launch height and it is assumed that the injuries followed launches from both heights. It is noted that a higher number of injuries occur during on-board ship drills than during shore-based training. The Swedish submission concludes that, 'During the launch of the free-fall lifeboat, there is a potential for the occupants to be injured'. As a result of these accidents interesting topic for further research and development has become evident: evaluation of performance of a free fall lifeboat in a wind and wave environments. In the paper the stochastic model of wave influence on the free fall lifeboat trajectory is presented.
