随着我国航运事业的发展,超大型船舶的发展趋势也越来越快,在对超大型船舶锚泊操纵中,这与普通万吨级的船舶也存在一定的区别,因此超大型船舶在实际操纵中操作人员一定要全面了解其的特点,并且只有熟悉以及掌握超大型船舶的操纵特性,才可以确保操纵的安全。以下本篇结合相关实例,分析超大型船舶锚泊操纵的基本方法。 相似文献

In order to verify the effectiveness of electrolytic treatment on ships' ballast water, experiments are carried out by a pilot system in laboratory. The raw seawater and seawater with different concentrations of different algae are simulated as ships' ballast water. The algae in the raw seawater can be killed if it is treated by electrolysis with an initial residual chlorine concentration of 5 mg/L. If the seawater with one kind of algae (Nitzschia closterum, Dicrateria spp., or Pyramidomonnas sp.105cells/mL) is treated by electrolysis with an initial residual chlorine concentration of 5 mg/L the alga can be sterilized, If the seawater with one kind of algae (Dunaliella sp., Platymonas or Chlorella spp.) is directly treated by electrolyzing with an initial residual chlorine concentration of 4 mg/L, the instant mortality changes with the concentration of different algae. However, after 72 hours, in all treated samples, there are no live algal cells found. 相似文献

渤海湾客滚船运输安全现状分析及安全对策 总被引:3,自引:0,他引:3
一、渤海湾客滚船运输安全现状 1.渤海湾客滚船运输的发展渤海湾客滚船运输兴起于1990年(当时的大连轮船公司购买了第一艘二手客滚船“天鹅”轮),发展于1993 年水上运输市场的全面开放。由于车客滚装运输中蕴藏着可观的经济效益,吸引许多船公司在不具备必要条件时匆忙上马,争相购船,而且购买的船大都是国外淘汰或即将报废的船舶,在短短数年中,许多小航运公司,私营的、合伙的海运公司相继问世,挤入这一高利润市场,造成水运市场的混乱和无序竞争。在交通部《老旧船舶运输管理规定》出台前,在此航线上营运的船舶仅两条是新船,其余全部是进口的老旧二手船舶,达十几艘之多。许 相似文献

非自航工程船舶锚泊设备配置计算探讨 总被引:2,自引:0,他引:2
随着深水港口建设的发展,外海施工项目日益增加,非自航工程船舶按照常规配置的锚泊设备已不能完全满足水上锚泊安全及移船作业需要。合理地配置、应用锚泊设备,将会有效地改善非自航工程船舶在深水海域的锚泊安全和移船作业效率。笔者根据非自航工程船舶锚机配置现状,对其合理性和安全性,通过对比分析和计算做些探讨。旨在从设备配置上进一步提高船舶安全作业能力。 相似文献

Sacrificial anodes have become a standard practice for the protection of ballast tanks of merchant vessels against corrosive damage. A well protected tank should extend the life span of a ship and consequently enhances its economic value. An in situ survey comprising more than 100 merchant vessels provided the opportunity to measure the impact of these anodes on the life expectancy of these vessels. Contrary to the general belief of these anodes’ beneficial effect, no significant difference was found in our observations in terms of corrosion occurrence between ship populations with and without sacrificial anodes, across all ship ages. This may be explained by the highly variable conditions and the complex geometry in a ballast tank severely impede optimal and straightforward installation of these anodes in these tanks. Also, poorly placed anodes in it may harm the integrity of the coating of the tank. We therefore plead for uniform and clear rules on anode installation and inspection. 相似文献
