本文从我国渔船实际情况出发,对《1972年国际海上避碰规则》中有关渔船号灯规定的若干条款,提出了修正意见。作者通过对渔船稳性和光学分辨率的分析,论证了“降低灯桅高度”、“缩小号灯间距”等的可能性和必要性。同时还对渔船号灯的规格,数量、位置、环照灯的遮蔽角等提出改革意见。这些意见如被国际海事组织(I M O)采纳,对我国渔船号灯的改装工程将是有利的。 相似文献

The authors have already examined a method for evaluating the capsizing probability of a ship in the dead ship condition based
on a piecewise linear approximation of the restoring arm. Here, this method is extended to ships with trapped water on deck.
This is because the stability of ships having a relatively high bulwark, such as fishing vessels, could substantially deteriorate
due to trapped water on deck. First, the mean amount of water trapped on deck was estimated as a function of the significant
wave height and the mean wave period using a model experiment in irregular beam seas. Second, the restoring arm curve with
trapped water on deck was calculated hydrostatically and then approximated with a piecewise linear curve. Third, the roll
angle was estimated using a nonlinear and uncoupled equation of absolute roll angle under stochastic wave and wind exciting
moments. The short-term and long-term capsizing probabilities were calculated for a fishing vessel operating off Kyushu. Numerical
results quantitatively demonstrated that the effect on capsizing probability of trapped water on deck cannot be ignored when
accurately evaluating the stability of fishing vessels. 相似文献

A new index, namely the overall motion induced interruptions (OMII), is proposed as a seakeeping criterion for fishing vessels, to compare ships having different hull forms and dimensions by means of an only parameter, in a human centred approach, mainly related to the onboard risk level. Therefore, the first aim of the paper is to investigate the factors affecting fishing vessels’ seakeeping performances to improve them to reduce the high number of injuries occurring during fishing operations, mainly related to both risk perception and harsh weather conditions. Despite the classical approach, where motion induced interruption is determined for a certain sea state with regard to several location points, the new index accounts for all crew members’ positions on the working deck, all heading angles the vessel may experience during fishing operations, based on relevant operating scenario, and all sea states the ship may encounter in the fishing area. The influence of position, heading angles and sea states on the attained risk level is fully investigated, analysing seakeeping performances of four fishing vessels with different hull forms and dimensions. Finally, a new operability criterion is proposed, based on OMII, to investigate the influence of ship size and operating scenario on the risk of injuries during fishing operations. Main factors affecting fishing vessels’ seakeeping performances are fully discussed, paying attention to relevant correlation with ship roll natural period. 相似文献

Fishing is one of the most dangerous occupations in the world. Numerous research studies have been carried out to improve fishing safety from many different perspectives. Several of these studies focused on the relationship between environmental factors, climate change effects, and fishing safety. This paper aims to suggest a knowledge mobilization structure that translates findings of this type of research into input of evidence-based decision making and consequently improve and update fishing policies with respect to fishing safety and environmental conditions. Significant safety factors extracted from related literature are stability of vessels, fisheries management, safety equipment, communication, insurance, training, safety information and culture, weather forecasts, fatigue, and search and rescue planning. The paper then reviews policies related to these factors to examine if they address extreme environmental conditions and climate change effects. The paper presents recommendations to improve general fishing safety with respect to short- and long-term environmental considerations. 相似文献
