江苏船舶产业结构分析

运用灰色系统关联度分析方法,对江苏省的造船产业、修拆船产业以及船舶配套产业的产值与总产值进行了关联度分析。序列图及量化结果均表明,江苏船舶产业是以造船产业为主,而船舶配套产业与修拆船产业跟不上造船产业的发展,整个船舶产业发展不平衡,产业结构不合理。然后运用区位熵分析法对江苏与全国船舶产业进行对比分析,与全国平均水平相比,江苏造船与船舶配套产业略占有优势,但修拆船产业较薄弱。最后针对分析结果,提出了相关建议。

Ship selection using a multiple-criteria synthesis approach

A method is presented for selecting a preferred ship from a group of candidates as a reference ship for a new design. The method is based on a recently developed approach for multiple-criteria decision analysis under uncertainty, the evidential reasoning approach. Using this method, both quantitative and qualitative attributes of a complicated nature can be considered in the selection process. The method consists of three phases: identifying suitable candidate ships, evaluating them in terms of both conventional techno-economical and qualitative attributes, and aggregating all the attributes using the evidential reasoning approach. This three-phase procedure is illustrated by means of an oil tanker selection example. The results of this study show that the evidential reasoning approach can support multiple-criteria ship selection processes when both qualitative and quantitative information with or without uncertainties have to be taken into account. The outcomes generated by the method include the ranking of the candidate ships and indications of their strengths and weaknesses in the format of performance distributions over different assessment grades. Such information is vital in helping decision makers to make an informed selection and be aware of any risk implication associated with the selection.

Foreland-based regionalization: Integrating intermediate hubs with port hinterlands

Development and changes in port hinterlands have received considerable attention as they represent substantial opportunities to improve the efficiency of global freight distributions. Port regionalization was a concept brought forward by Notteboom and Rodrigue (2005) to articulate the emerging port hinterland dynamics in light of containerization, supply chain management and the setting of inland terminals. This paper expands this concept by focusing on a particular dimension of the regionalization paradigm concerning the evolving role of intermediate hubs. It is argued that, in addition to hinterland-based regionalization, there is also a foreland-based regionalization where intermediate hubs capture a maritime hinterland. This intensity and viability of processes of foreland-based regionalization depend on multiple geographical, technical and market-related factors, and this paper identifies and analyzes these underlying parameters. By doing so, it assesses whether foreland-based regionalization is simply a transitional phase in port development or, alternatively, represents emerging functional characteristics of contemporary freight distributions.

Evaluation of safety and environmental risk at individual ship and company level

Whereas current risk profiling methods used in the maritime sector largely rely on detention risk, we extend them by considering various risk dimensions and by evaluating a wide range of risk factors including pollution and damage costs. Risk factors include ship particulars such as vessel type and the nature of companies and owners, as well as historical information on past accidents, inspections, and changes of particulars. We present methods to summarize and visualize the various risk dimensions paying particular attention to the identification of potentially risky companies. The results are obtained by combining unique data sets with information on ship arrivals, inspections, and accidents covering 2006-2010.     

Integrating banks’ decision on financing dry bulk shipping: a multivariable approach

ABSTRACT

Shipping is characterized by extreme changes in revenues, operating expenses and asset values, making shipping banks’ final decision for financing shipping market considerably harder. This paper develops a practical decision tool based on the estimation of the credibility factor in the decision-making process, each bank’s policy, and the most significant variables arising from both its operating environment and the dry bulk market. Revealed relationships between bank’s internal environment, its own policy, and dry-bulk shipping market conditions through GDP growth of China constitute a newly presented decision framework in shipping finance. The values of credibility factor implicate either an aggressive or passive defensive strategy taking into account the GDP China changes: Consistent with the economic growth of China, a bank’s holds an aggressive policy if the credibility coefficient is about one. On the other hand, the model predicts that a less aggressive policy in combination with the increase of China’s GDP would drive to the decrease of bank’s loan grants.     

Environmental regulations in shipping: Policies leaning towards globalization of scrubbers deserve scrutiny

Emission regulations for Sulphur oxides (SOx) and nitrogen oxides (NOx) are motivated by health- and other environmental objectives in local and regional settings, while global warming concerns motivate policies for carbon dioxide (CO₂). We point out that the direction chosen by the International Maritime Organization (IMO) – to tighten SOx and NOx limits globally – carries important risks. First, extending to a global setting the present regulations in coastal emission control areas (ECAs, in North America and Northern Europe) gives negligible or negative environmental benefits, and raises global warming impacts. Second, ‘end-of-pipe’ solutions, such as scrubbing and tuning, become dominant responses, and they reduce energy efficiency. Third, the adoption of these end-of-pipe solutions carry risks of deflecting attention from development of cleaner fuels and improving energy efficiency. Distinguishing local environmental benefits from global ones is important in general, and our research concludes that in the case of shipping, this distinction better serves the needs of the local environment, the global climate, and conserves on abatement costs.
