水上石油运输的快速增加将导致船舶污染海洋环境事故的风险逐年加大,制定有效的风险降低措施来减少事故的风险显得十分必要。科学的水上污染事故风险可接受标准可以为水上污染事故的风险管理和决策制定提供良好的理论依据。文章对目前船舶污染海洋环境风险评价技术进行了分析探讨,结合水上污染事故风险的特点,提出了利用FN曲线来确定水上污染事故可接受标准的方法,并选择合适ALARP边界的确定方法。通过对舟山地区的船舶污染风险评估验证计算,得出基于FN曲线的水上污染事故风险评估方法可以更好的表达风险可接受水平以及污染量与水上污染事故频率之间的关系,更好地提供评价结论,为管理者提供决策依据。 相似文献

This paper describes the current situation with piracy and armed robbery at sea in the Indo-Pacific region, particularly off the Horn of Africa and in Southeast Asia. This situation may be aggravated due to the downturn in international shipping following the global financial crisis. This has led to surplus shipping capacity, crews paid off, lower profits, and ship owners seeking to cut costs. Many ships are laid up in anchorages prone to sea robbery, and there is a risk that ships might be less well maintained and operated. This paper also explains how some ships are more vulnerable to attack than others. Sub-standard ships are more likely to be successfully attacked than quality vessels. Issues are identified that might be addressed by the shipping industry and ship owners, as well as by the International Maritime Organization (IMO). In addition to being a victim of piracy, the shipping industry could be adding to the problem by laying up ships in vulnerable areas, reducing wages and sizes of crew and employing sub-standard ships. This situation could be symptomatic of wider problems in international shipping that throw doubt on the effectiveness of current regimes for ship safety, security and marine environmental protection. 相似文献

Strategies of fuel consumption onboard ships are of one of the crucial issues in marine shipping industry. Many of the relevant authorities maritime domain gave great interesting to that issue, either through research that discussed the impact of marine fuel consumption on the environment and economy of ships or through practical experiments’ that are made by marine engine manufacturers. Over the years, many solutions have been put forward to overcome this problem while maintaining the amount of goods transported globally at the same transfer rate and ship speed. The present paper sheds light on many of the methods used currently to reach this purpose. It is explained that applying a certain fuel-saving strategy will rely on some of the factors, especially the type of ship. Mainly two methods including: shore-side power and cold out of heat strategies have been investigated regarding adaption, economic, and environmental issues in case of applying onboard high-speed passenger ships. 相似文献

船舶交通量受多种环境与社会因素的影响,使得船舶交通量预测存在复杂性与非线性的特点.在分析现有预测模型和方法不足的基础上,介绍了广义回归神经网络GRNN的基本原理与拓扑结构.不同类型船舶受各类因素影响的程度不同,根据天津港VTS(Vessel Traffic Services)中心提供的船舶交通量数据,按船舶种类将船舶交通量分为六类,利用GRNN神经网络分别进行预测.预测结果表明GRNN神经网络具有很强的非线性拟合能力,有效解决了天津港船舶交通量预测中的小样本问题,提高了整个预测系统的精度与稳定性. 相似文献
