| Abstract | Fishing vessel habitability is a growing issue of concern given the current realities that the Newfoundland fleet has to venture further offshore for more extended periods of time in order to compete for fish stocks. These issues are further complicated by the fact these vessels were not designed to accommodate the harsh ocean and environmental conditions typical of the seasonal dates regulated for harvesting. This paper looks at how such parameters as MII (Motion Induced Interruptions), postural stability vary in different vessels of the fleet. The results are based on the recently conducted sea trials of the five example vessels of the fleet and their corresponding numerical simulations using MOTSIM. MII, or other relevant parameters can be computed for different locations onboard, which might correspond to the locations of different harvesting or operational activities, for given sea conditions. The paper presents results for motion levels as well as human factors related parameters for the vessels used in these sea trials. The lengths of the vessels are 10.7, 13.7, 19.8 and 24.9m, which approximately cover all sizes included in the fleet. |
