投资尼日利亚港口 促进中尼资源合作

尼日利亚位于非洲西部．面积923768km^2．2007年全国总人口1．481亿。尼日利亚是一个滨海国家,拥有众多的天然良港．全国各港口共有93个一般货物泊位,3个滚装货物泊位,7个大宗固体货物泊位,11个大宗液体货物泊位。63个浮标泊位和一批私人码头。其中主要港口有拉各斯港、瓦里港、哈科特港、奥尼深海和中心港、卡拉巴尔等13个海港,总装卸能力3500多万t。其中拉各斯港为西非最大、设施最好、吞吐量最大和最繁忙的港口。     

倒航靠泊技术在东营港5号泊位的应用

东营港中海油码头5号泊位的走向与泊位附近的流(往复流)向接近一致。当落潮流时,大型油船顺流左舷靠泊操纵比较困难,如果在该泊位回旋水域向左掉头顶流右舷靠泊,又存在触碰东营港公共引桥的风险,所以通常选择涨潮流时顶流左舷靠泊。落潮流时大型油船不能安全靠泊作业对码头生产效率和船期周转产生不利影响。     

锦州港最大通航能力探析

锦州港作为一个较早实行股份制改造的区域性港口,其上市公司的特点促使港口生产营运必须超常规发展。但锦州港正在营运的８个万吨级以上泊位中仅一个５万吨级油泊位,２个３．５万吨级杂货泊位和一个３万吨级杂货泊位,就是２０２０年远期发展预测船型中,仍没突破５万吨级船型。显然,现有的港口能力没有更多的硬件优势。而全球经贸活动中,无论是货方还是港方都愿意单船一次性大量运输货物;拥有或经营超大型船舶的船东或经营人也希望承揽到更多不同目的港的大批货物,以期提高经济效益和自己在更多航运货物流向地的海运市场的占有率。但…

斯里兰卡港口

<正>一、主要港口1.科伦坡港科伦坡港主要从事集装箱货物装卸处理,集装箱处理能力远远超过该区域其他港口,已经成为一个主要的集装箱转运枢纽。此外,该港还装卸普通杂货、干散货以及油品。科伦坡港吞吐量近几年来保持了较高的增长速度,2006年科伦坡港吞吐量为3943万t,其中集装箱吞吐量308万TEU。2020年科伦坡港预计需要中转980万TEU。在斯里兰卡港口战略发展中,科伦坡港定位为集装箱枢纽港。因此科伦坡港计划把一些普通货物泊位转换成集装箱支线泊位。

日照港集装箱班轮航线开通的有关问题

集装箱运输无论对货方、港方还是船方都是十分感兴趣的运输方式。对货方而言，货物包装简单，一次报关即可一票到底，实现了货物的门到门运输，简化了办事手续；对港方而言，集装箱装卸速度快，集疏运迅速，易于保管，既提高了泊位利用率，增加了经济效益，又减少了货物在港储存期间被盗、被日晒雨淋而造成的货差、货损等质量事故；对承运方而言，集装箱运输快捷，船舶在港停泊作业时间减少，动态营运时间相对增加．成本相对减少。

Cost analysis of bulk cargo containerization

ABSTRACT

Bulk cargo containerization (BCC) involves changes in the transportation mode of container shipping for cargo that uses bulk carriers without packing. This topic has recently attracted considerable attention as an alternative transportation method for container cargo. BCC is advantageous because it can address imbalances in the amount of cargo conveyed between the main and back hauls, thereby improving efficiency. A previous survey among companies involved in cargo shipping revealed that in addition to ocean freight, vanning and devanning, and customs clearance costs, consignees’ decisions were the key factor in selecting transport modes. The present study aims to clarify the cost competitiveness of container shipping and identify cost reductions that may increase the use of BCC. To quantitatively check the results of the survey employed in this study, we constructed a model based on consignees’ and container shipping companies’ costs to determine the choice of transport mode for back-haul trade, then examined the incentives for consignees and shipping companies. We found that BCC can be realized by cost reduction on the part of the consignee and profit improvement on the part of the container shipping company for some routes and goods. Although reducing the freight rate would effectively promote BCC, reducing other costs would not have the same effect.     

天津港老旧码头加固和加深改造

船舶大型化可降低货物的海运成本,也要求港口设施随之向深水化、大型化发展.近年来由于大型深水泊位数量有限,不少港口采取将大船减载后靠泊小吨级码头的作业方式,以解决燃眉之急,这种作业方式虽然能取得一定的经济效益,却带来很多安全隐患,尤其是对于使用年限已久的老旧码头,需注意及时进行加固改造,通过对近年来天津港老旧码头泊位加固...     

Panama Canal expansion: fuel economy and logistical risk

Since cargo capacity increases faster than fuel consumption, the significantly larger capacity fleets which will accompany expansion of the Panama Canal will introduce additional fuel economies and cost savings. Enabling larger, more fuel-efficient vessels to carry cargo the entire distance from Asia to US east-coast ports allows vessel operators to realize significant and meaningful savings compared with the alternatives of using smaller Panamax vessels for the whole distance, or sending the cargo over the US land bridge by train or truck. Fuel savings are quantified along with the monetary savings based on various assumptions for the price of fuel. These savings are dramatic and will increase directly with the price of crude petroleum. Finally, microeconomic theory is deployed to determine how cost savings will be distributed between shipping customers and vessel operators.     

浅议油船改装沥青船

沥青船主要从事沥青的远洋商业运输,为了方便货物的装卸、运输及安全等诸多因素,需要将沥青加热至液态储存在货舱内,并要求保持货舱恒温,由此对沥青船舱室的保温有着很高的要求。与其他舱室相邻货舱的舱壁反口、首尾横舱壁、边纵舱壁、上下斜坡、舯壁墩、横舱壁壁墩、梯道等处均需铺设保温材料作为绝热层,以有效阻止货舱区域热量的散失。文章总结了某船舶修理公司将某油船改装成沥青船的修理工程,从5个方面详细分析了沥青船改装的技术难点,以期对其他船厂对于该类型船舶的修理起到借鉴作用。     

Intermodal route selection for cargo transportation from Korea to Central Asia by adopting Fuzzy Delphi and Fuzzy ELECTRE I methods

Due to the increase in trade from Korea to Central Asia, an efficient intermodal route for transporting cargo is important. Intermodal routing for long-distance transportation faces operational challenges, such as customs clearance, track gauge differences, and climate limitations. The initiative of the Silk Road Economic Belt recently proposed in China could improve trade and transport links in Asia and create an efficient transportation route that focuses on the railroad service provided in China. The objective of this study is to obtain an evaluation structure for intermodal routing and then find the route for transporting cargo from Korea to Central Asia under China’s Silk Road Economic Belt with integrated Fuzzy Delphi and Fuzzy (Elimination Et Choice Translating Reality (ELECTRE) I methods. After a sensitivity analysis is performed, development strategies and alternative routes are suggested. The results show that among the five principal factors, total cost is the most important factor for logistics companies when they select a transportation route, followed by reliability, transportation capability, total time, and security. Of the sub-factor weights, transportation costs and cooperation and emphasis among state organization are important. In the intermodal route results, route 3, Incheon to Qingdao to Horgos to Almaty, is preferred.

船载固体散货流态化数值分析

散货船装载的镍矿、铁矿在运输过程中会发生流态化,流态化导致货物流动性增强,从而降低船舶稳性。当船舶在波浪中航行时,货物的移动会产生一个额外的力矩,该力矩有可能导致船舶倾覆。基于离散元方法,对不同含水率的货物进行了静倾斜、休止角的数值模拟,在全尺度计算中给定了颗粒尺寸和时间步长的选取标准,并采用全尺度货舱模型分析了影响货物稳定性的关键参数。该数值分析方法可为固体散货海上运输过程中船舶稳性预测和安全隐患评估提供参考。     

Panama Canal expansion: alleviating global climate change

This paper quantifies likely changes in greenhouse gas emissions which contribute to anthropogenic climate change, resulting from the expansion of the Panama Canal and the consequent increase in ship-borne commercial transportation from east Asia to the US east coast. Ocean transportation offers higher fuel economy and lower pollutant emissions compared with land transport. Additionally, truck and train transportation of cargo along the US land bridge threatens to overwhelm existing highway and rail systems and limit economic growth. The alternate transportation route for easterly transit of the Panama Canal will reduce overland traffic congestion and enhance economic development by maintaining freight flow efficiency.     

Optimizing the transportation of international container cargoes in Korea

This paper considers a multimodal transportation problem, which is the problem of determining the transportation flow, i.e. volume of container cargoes, and the transportation mode in each trade route, for the objective of minimizing the sum of shipping and inland transportation costs. The problem takes account of two restrictions: maximum cargo volumes capacitated at each seaport and maximum number of vehicles available at each transportation mode. To solve optimally the problem, this paper employs a mixed integer programming, which is an operations research technique. A case study is performed on the container cargo data in Korea and we draw several implications to improve efficiency in the transportation of international trade cargoes in Korea.
