随着国民经济的高速发展,乡镇造船业呈现出一片欣欣向荣的局面.一些船厂为适应市场需要,扩大生产规模,摆脱通航条件限制,跻身大吨位造船市场,还在沿江一带兴建新的造船基地.船舶生产从小吨位普遍向大吨位、沿海货船、集装箱货船及大吨位油船等类型发展. 相似文献

9月份,国际船市低迷,价格疲软下跌,仅有灵便型成品油船和阿芙拉型油船成交较为活跃,其它类型新船成交仍然不如所望,造船市场已成为买方市场。VLCC船价虽已从去年的7800万—8000万美元跌至如今的7500万美元,但在9月份仅有2艘成交,预计VLCC的船价还可能下跌,预测今年底将跌至7300万美元。阿芙拉型油船船价目前为4100万美元,日本佐野安赢得意大利船东的2艘阿型船订单,船价仅为3950万美元。4.5—4.7万载重吨的灵便型成品油船,船价已跌至2900万~3100万美元。俄罗斯海军上将船厂接有6艘4.7万载重吨的油船,韩国现代尾浦接有2艘4.7万载重吨的成品油船,乌拉尼克船厂接有4艘4.5万载重吨的成品油船,均在此价位上成交。 9月份确认的油船订单吨位从8月份的200万载重吨猛增到380万载重吨;而确认的散货船订单吨位却从8月份的70万载重吨下跌到50万载重吨;2.7—3.7万载重吨的成品油船已有40%以上船龄满20年,预计未来几年将出现该型船的订造高潮,船价也将随之而涨。 相似文献

近年来油船的数量和吨位越来越大,油船进出港口次数日渐增加,船舶发生海损事故的几率也随之增加。由于船舶碰撞等海难事故而发生的溢油,也成为海域污染的主要污染源之一。目前我国的海上溢油应急防治能力还是较低的,与国际上相关先进成果相比,理论和实用性方面均有一定差距,提高海上溢油应急反应能力刻不容缓。 相似文献

今年6月,适逢江南造船厂成立120周年之际,该厂将开工建造6.5万吨级油船。这次为广州海运局建造的两艘6.5万吨级油船,无论从造船品种和造船吨位上来说,都是一个可喜的突破。前几年,江南造船厂进行了以提高造船综 相似文献

分析2013年重点监测海洋船舶和内河船舶的油耗总量、单位油耗,对干散货船、集装箱船、油船等海洋运输不同船型和内河货运船舶的不同船型进行监测,分析不同船型、吨位的油耗特点及相关影响因素,同时针对不同船型提出相应的建议:对于干散货船,应加快淘汰老旧船舶,调整船舶动力结构;对于油船在货源充足的情况下,大型化更有利于油船节能降耗。 相似文献

近年以来,在世界石油能源需求不断增长和中国原油进口量逐年上升情况下,国际油船市场一直稳中趋升;我国进口石油的数量不断增加,而国内航企油船承运的份额确实偏低,需建立大型油船船队以扩大我国远洋石油运输能力。随着造船技术水平的提高,国内船企有望不断扩大承建VLCC的市场份额,我国超大型油船建造市场前景广阔。 相似文献

The surplus of tonnage which has characterized the shipping industry for over a decade has severely affected profitability and investment opportunities in the industry. This has prompted various schemes to reduce the surplus. A proper assessment of the size of the surplus is an essential requirement for sound policy measures. This paper, which focuses on the tanker sector, examines selected methods used to compute surplus tanker tonnage and proposes other methods. It observes that methods currently used give estimates of surplus tonnage which are basically identical to those obtained by using alternative methods. It concludes that while from 1984 the surplus tanker tonnage has been declining, from 1986 the decline has been rather small and the volume of the surplus is likely to stabilize in the next few years at more or less current levels. However, the paper points out conceptual and practical problems of determining the appropriate base periods or base operating conditions upon which surplus tonnage may be computed. 相似文献

This paper examines the world-wide supply and demand for new oil tankers. A simultaneous supply and demand model is developed and estimated using two-stage least squares techniques and empirical data from 1972 to 1983. The relationships between tanker newbuilding orders and prices, and other relevant market factors are analysed. Major factors affecting the tanker new building market are identified. The results indicate that: oil price and second-hand tanker price are predominant factors influencing future newbuilding demand; a moderate decrease in laid-up tonnage would not induce a significant increase in newbuilding orders; shipbuilding capacity is a more influential factor for the short-run supply of new tankers than shipbuilding cost. Technological change has also played an important role in the market. 相似文献

A simulation model of individual ship movements demonstrates that distance-weighted regional imbalances of tonnage supply and demand are powerful estimators of tanker rates that are converted to approximate time charter equivalents. Statistical fit is acceptable to good when cargo cycles (ballast-load-cargo-discharge) are the units of observation, either individually or aggregated by region. Up to 30-40% higher average time charter equivalent is possible in an outstanding year, such as in 2004, when consistent use is made of this feature. 相似文献

对比了英标和PIANC两本规范关于船舶撞击能量计算的异同,并就护舷设计吸收能与中国规范进行了比较分析,就撞击能计算中的偏心系数开展了进一步研究。得出结论:1)英标及PIANC规范船舶撞击能量计算中偏心系数、水动力质量系数和异常靠泊能量系数等参数取值不同。2)英标的集装箱船撞击能设计值大多小于PIANC,而油船撞击能设计值大于PIANC。3)油船采用三分点靠泊时撞击能量约为四分点靠泊时的1. 3倍左右。4)油船及气体运输船管汇偏中影响着偏心系数C_E取值,随着船舶吨级增大而减小,影响程度为12%~29%。 相似文献
