苏伊士运河是在埃及境内,南北方向横跨苏伊士地峡,人工挖掘的无船闸海平面水道,其连接红海与地中海,该运河将非洲大陆与亚洲分隔开,且在欧洲与沿印度洋和西太平洋周边的陆地之间,提供了最短的海上航路。2015年8月6日,扩建后的苏伊士运河新航道开通。苏伊士运河由"苏伊士运河管理局"(SCA)负责管理、作业和维护,现行的SCA航行规则为2015年8月版,其与船舶设计、建造关系密切。文中对航行规则中的目次、舷梯和引水员软梯、系泊索、指示器、消防设备和起居舱室等作了介绍。 相似文献

埃及计划于2010年前扩建苏伊士运河,证券分析家对其经济效果提出了质疑。按照计划,将投资10亿美元,将运河浚深至21米,宽度扩大到365米,但是,对通行费上调的忧虑令人关注。苏伊士运河管理局预计1万TEU级集装箱船和超大型油轮的需求将上升,但证券分析家认为运河现在的尺度就能充分应对。 相似文献

随着2014年巴拿马运河扩建工程即将完成,原巴拿马型船对于扩建后的运河而言,已经显得太小而不经济。那么,巴拿马型船是否会面临被逐步淘汰的局面,其未来前景将如何呢? 相似文献

投资总额高达52.5亿美元的巴拿马运河扩建工程于当地时间2006年10月22日进行公民投票时,以巴拿马前总统豪尔赫·伊柳埃卡为代表的反对派就扩建的资金来源、成本上升、按时完工等问题提出质疑。尽管最终运河扩建计划得以顺利通过,但针对扩建工程的各种质疑声从未间断,特别是2007年2月美国次贷危机显露并进一步演化成席卷全球的金融危机,运河扩建工程能否顺利实施更加受到关注。 相似文献

本文概要介绍了该运河的简况,运河上的各船闸的长度、宽度和深度,运河对通航船舶的尺度限制等.简要阐述了巴拿马运河的扩建,即2014-2015运河将能通过12000TEU的新巴拿马型(NTX,New Panamax)集装箱船.文中还简要介绍了《巴拿马运河操作规则》与《作业部航运通报》,特别是,《作业部航运通告》每年出新版,是设计者必须了解的,从某种意义上,它比航行规则更实用.文中对《作业部第N-1-2008号通告》(对船舶的要求)作了概要介绍. 相似文献

The hydrophysical and hydrochemical structure of the Sea of Azov, with developed bottom anoxia, was studied during the RV “Akvanavt” cruise from July 31 to August 03, 2001. The anoxic zone with a thickness from 0.5 to 4 m above the bottom was found in all deep regions of the Sea. Concentrations of hydrochemical parameters were similar to the pronounced anoxic conditions (about 90 mmol m− 3 of hydrogen sulfide, 17 mmol m− 3 of ammonia, 6 mmol m− 3 of phosphate, 7 mmol m− 3 of total manganese). The hydrophysical structure was characterized by the uniform distribution of temperature in the upper 6–7 m mixed layer (UML). Below this a thin (0.4–0.8 m) thermocline layer was observed, just above the anoxic waters. Formation of this phenomenon was connected with that summer weather conditions. Intensive rains led to increased influx of river waters in June. That resulted in large input of allochtonous organic matter (OM) and inorganic nutrients; the latter were consumed on the additional autochthonous organic matter production. In July the weather was characterized by a significant rise in the daily averaged air temperature and large oscillations of temperature during the day. In this period a wind of constant direction was absent, but wind bursts were observed. The completed analyses showed that the formation of such a structure could be connected with the following factors: (i) positive growth trends of the daily averaged temperature and the daily oscillations of temperature, (ii) presence of wind bursts. The joint action of these factors resulted in the formation of the UML. The amplitude of wind bursts determined the depth of UML, and the value of trend determined the value of the temperature change in the thermocline. An initial presence of bottom halocline (caused by the Black Sea water influx to the bottom of the Sea of Azov) prevented the heating of the bottom layer and therefore led to an increase of vertical gradient of temperature in the thermocline. The spatial distribution of the turbulent exchange coefficient confirmed the existence of a “stagnation” area located above the anoxia zone, which is also, apparently, the reason for its occurrence. 相似文献
