Mantari, J.L., Ribeiro e Silva, S. e Guedes Soares, C. (2009), “Intact Stability of Fishing Vessels under Operational Loading Conditions”, Proceedings of the 13th Congress of International Maritime Association of the Mediterranean (IMAM´09), 12-15 October, Istanbul, Turkey
The safety of fishing vessels remains a key concern giving the high rates of accidents that occur worldwide. In particular, capsizing of the vessel is one of the biggest risks, mainly due to the high number of fatalities that often causes. Therefore, even when the statistics give a few percentages of occurrences related to capsizing for dynamic stability, safety of fishing vessels, particularly small, remains a subject of great importance, which has been confirmed by the intense legislative activity carried out by IMO. In this paper a set of fishing vessels were considered to study the intact stability in waves, considering rough weather, and fishing gear forces. The calculations were made for longitudinal waves: own, trough and crest waves for one of the most critical ship length to wave length ratio, and for beam waves where corrections were introduced to the amount of restoring energy available to counteract the most significant external loads applied: wind and fishing gear. The results were compared with applicable IMO rules for still water intact stability, and some conclusions were drawn about the change of stability due to ship size, hull form, and operational loads. Based on their length, a set of six fishing vessels from the Portuguese, Spanish and Peruvian fleet were classified into three different groups for this study.
