1油价走势判断
自2007年第3季度起,纽约原油期货价格不断刷新历史最高纪录,2008年的首个交易日突破100美元/桶关口;到7月11日,更进一步创下147美元/桶的历史新高。尽管此后油价出现下跌,8月底至9月初更跌破110美元/桶,但依然保持在100美元/桶以上。这意味着,一个超级飙升的高油价时代业已来临。造成油价飙升的原因主要有以下几方面:(1)需求拉动;(2)地缘政治;(3)美元贬值;(4)投机因素。特别是后两个因素,已成为推高油价的关键。 相似文献

由于原油价格的大幅上扬,导致国际船用油价居高不下,除了让船公司经营成本大增,更将打击航商的获利能力.现在大多数的航商都处于惨淡经营的状态,1996年以来世界航运业就已走入低迷时期,近期虽然稍有好转,但运输成本的飚升已使这点利好显得微不足道. 相似文献

在全世界现役数千艘油轮中 ,60 %为单壳油轮 ,历史上 5次最大规模的原油泄漏事件 ,都是由单壳油轮所造成 ,泄漏已达 3 60万t,平均每年 2 0~3 0万t原油污染海洋。据专家估计 :单壳油轮的失事要比双壳油轮高 5倍 ,而发生泄漏的几率也大得多。淘汰单壳油轮 ,净化海洋环境已经成为 相似文献

Parametric optimization was applied to a double-hull AFRAMAX tanker design in order to reduce oil-outflow probability and increase cargo carrying capacity, and the results are presented here. A multi-criteria optimization procedure was set up in modeFrontier ® using the cargo volume, the mean oil-outflow parameter and the steel weight of the cargo block as the objective functions. Calculations are based on a parametric geometric model of the ship created in NAPA ®, and on a structural model created in POSEIDON ®. Integration of the above software packages leads to an automated optimization procedure that provides improved feedback to the designer regarding the trade-off between the various design parameters and optimization criteria involved. The results obtained suggest notable improvements in transport capacity and oil-outflow performance for known, well-established yard designs. The presented work derives from a joint industrial project between Germanischer Lloyd (GL) and the Ship Design Laboratory of the National Technical University of Athens (NTUA-SDL), which continues the work done and coordinated by NTUA-SDL within the SAFEDOR project on the same subject. 相似文献

Given the secular and sharp rise in oil prices over the past decade, this study analyses the impact that the spike in oil prices has on tanker rates. We investigate a dynamic model explaining spot tanker rates. The magnitude of the impact of oil prices on the shipping industry, in terms of the level and volatility of spot (voyage) under bull and bear market conditions. The West African–US Gulf Tanker Rates, West Texas Intermediate spot and 3-month futures contract, and US Weekly Petroleum Inventories are analysed using cointegration and Granger causality analysis, from 1997 through 2007, in order to examine the lead–lag relationship between oil prices and tanker freight rates. Our findings show a relationship between spot and future crude oil prices, crude oil inventories and tanker rates. The significant increase of freight rates, and the simultaneous increase in oil prices, during the recent years, provides an intriguing economic environment to identify relationships between shipping market rates and oil prices. These relationships have significant implications for the markets. At the practical level, the better understanding of the relationship between freight rates and crude oil prices can improve operational management and budget planning decisions. 相似文献
