Purpose The rapid growth in cruise shipping coupled with increasing public awareness of climate change has led to increasing concerns about the impact cruise shipping poses on the environment, especially regarding air emissions. This study analyses the cruise shipping network of ports in and around the emission control areas (ECAs) to understand the structural properties of the network and ports. Design/methodology/approach A complex network approach was used to analyse the network data of 239 voyages serviced by 14 international cruise lines, visiting 127 ports across 44 countries in the Caribbean Sea. Findings It is found that the network has a small-world property with a short average path length and a high clustering coefficient. The regulations affect connections among ports, in which most ports in ECAs have lower connections than ports outside ECAs. A few ports in ECAs play important key roles, but many ports outside ECAs play a more important role in the network because the regulations are barriers for cruise ships entering the ports. Originality/value The findings of this study have drawn useful guidelines for cruise lines and port authorities to improve their operations. Constrictive recommendations are suggested to policymakers for designing reasonable regulations to attract more cruise shipping to travel in ECAs.
邮轮业的快速增长,加上公众对气候变化意识的提高,导致人们越来越关注邮轮对环境的影响,特别是对空气排放的影响。本文通过对排放控制区内及周边港口的邮轮网络进行分析,了解该网络及港口的结构特征。设计/方法/方法采用了一种复杂的网络方法来分析14家国际邮轮公司服务的239次航行的网络数据,这些航行访问了加勒比海44个国家的127个港口。结果表明,该网络具有平均路径长度短、聚类系数高的小世界特性。这些规定影响到端口之间的连接,大多数eca内端口的连接数低于eca外端口。少数港口在eca内发挥着重要的关键作用,但许多eca外的港口在网络中发挥着更重要的作用,因为这些规定是邮轮进入港口的障碍。这项研究的结果为邮轮公司和港口当局提供了有用的指引,以改善其运作。建议决策者设计合理的法规,以吸引更多的邮轮在eca旅行。

PurposeCompetition among seaports is rapidly increasing due to various factors such as the global recession, resurgence of COVID-19, tight environmental regulations of IMO, sharp rise in ocean freight charges, increasing global uncertainties and growth in ship sizes. It is essential to have precise knowledge of shipping companies' port selection factors to secure the competitive advantage of seaports. This study aims to empirically analyze recent changes in the importance of port selection factors.Design/methodology/approachBy employing a longitudinal study, this study conducted the t-test analysis. The first survey was conducted from January 2005 to April 2005. Then, the second survey was conducted in May 2021.FindingsFirst, the importance of port facilities (berth length and the number of berths, shed and terminal areas, possession of adequate equipment and maximum berth size) increased significantly. Second, while ship and cargo safety were the critical port service factors in previous studies, speed, flexibility and reliability for handling cargo and berthing schedule were found to be crucial in this study. Third, the importance of ship arrival/departure frequency, route diversity and ship arrival/departure information systems increased when shipping companies selected the port.Originality/valueThis study has academic significance in that it reveals the changing importance of port selection factors in the 2020s and has taken the form of a longitudinal study on the importance of port selection factors from 2005 to 2021, moving beyond the cross-sectional approach. This study can provide valuable insights into and implications for port policymakers and managers when developing and formulating port policies and strategies.
目的由于全球经济衰退、新冠肺炎死灰复燃、国际海事组织严格的环境法规、海运费大幅上涨、全球不确定性增加和船舶规模增长等多种因素,海港之间的竞争正在迅速加剧。必须准确了解航运公司的港口选择因素,以确保海港的竞争优势。本研究旨在实证分析港口选择因素重要性的近期变化。设计/方法/方法通过采用纵向研究,本研究进行了t检验分析。第一次调查于2005年1月至2005年4月进行。然后,于2021年5月进行了第二次调查。发现首先,港口设施的重要性(泊位长度和泊位数量、棚屋和码头区、拥有足够的设备和最大泊位尺寸)显著增加。其次,虽然在之前的研究中,船舶和货物安全是港口服务的关键因素,但在本研究中,处理货物的速度、灵活性和可靠性以及停泊时间表至关重要。第三,船舶到达/离开频率的重要性,当航运公司选择港口时,航线多样性和船舶到达/离开信息系统增加。原始性/价值这项研究具有学术意义,因为它揭示了港口选择因素在20世纪20年代的重要性变化,并采取了对2005年至2021年港口选择因素重要性的纵向研究的形式,超越了横截面方法。这项研究可以为港口决策者和管理者在制定和制定港口政策和战略时提供有价值的见解和启示。

PurposeAn integrated queueing network focused on container storage/retrieval operations occurring on the yard of a transshipment hub is proposed. The purpose of the network is to support decisions related to the organization of the yard area, while also accounting for operations policies and times on the quay.Design/methodology/approachA discrete-event simulation model is used to reproduce container handling on both the quay and yard areas, along with the transfer operations between the two. The resulting times, properly estimated by the simulation output, are fed to a simpler queueing network amenable to solution via algorithms based on mean value analysis (MVA) for product-form networks.FindingsNumerical results justify the proposed approach for getting a fast, yet accurate analytical solution that allows carrying out performance evaluation with respect to both organizational policies and operations management on the yard area.Practical implicationsPractically, the expected performance measures on the yard subsystem can be obtained avoiding additional time-expensive simulation experiments on the entire detailed model.Originality/valueAs a major takeaway, deepening the MVA for generally distributed service times has proven to produce reliable estimations on expected values for both user- and system-oriented performance metrics.

PurposeWhile previous studies focused mainly on East Asia to Europe or United States trade routes, in recent years, trade among South-East Asian countries has increased notably. The price of transporting a container is not fixed and can fluctuate heavily over the course of a week. Besides, extant literature only identified seasonality patterns in the container freight market, but did not explore route-varying seasonality patterns. Hence, this study analyses container freight seasonality patterns of the six South-East Asian routes of the South-East Asian Freight Index (SEAFI) and the index itself and forecasts them.Design/methodology/approachData of the composite SEAFI and six routes are collected from the Shanghai Shipping Exchange (SSE) includes 167 weekly observations from 2016 to 2019. The SEAFI and individual route data reflect spot rates from the Shanghai Port to South-East Asia base ports. The authors analyse seasonality patterns using polar plots. For forecasting, the study utilize two univariate models, autoregressive integrated moving average (ARIMA) and seasonal autoregressive neural network (SNNAR). For both models, the authors compare forecasting results of original level and log-transformed data.FindingsThis study finds that the seasonality patterns of the six South-East Asian container trade routes are identical in an overall but exhibits unique characteristics. ARIMA models perform better than SNNAR models for one-week ahead test-sample forecasting. The SNNAR models offer better performance for 4-week ahead forecasting for two selected routes only.Practical implicationsMajor industry players such as shipping lines, shippers, ship-owners and others should take into account the route-level seasonality patterns in their decision-making. Forecast analysts can consider using the original level data without log transformation in their analysis. The authors suggest using ARIMA models in one-step and four-step ahead forecasting for majority of the routes. The SNNAR models are recommended for multi-step forecasting for Shanghai to Vietnam and Shanghai to Thailand routes only.Originality/valueThis study analyses a new shipping index, that is, the SEAFI and its underlying six routes. The authors analyze the seasonality pattern of container freight rate data using polar plot and perform forecasting using ARIMA and SNNAR models. Moreover, the authors experiment forecasting performance of log-transformed and non-transformed series.
虽然以前的研究主要集中在东亚到欧洲或美国的贸易路线上,但近年来,东南亚国家之间的贸易显著增加。运输一个集装箱的价格不是固定的,在一周内可能会有很大的波动。此外,现有文献仅识别了集装箱货运市场的季节性模式,而没有探索航线变化的季节性模式。因此,本研究分析了东南亚运价指数(SEAFI)及指数本身的6条东南亚航线的集装箱货运季节性模式,并对其进行预测。设计/方法/方法综合航海指数和6条航线的数据来自上海航运交易所(SSE),包括2016年至2019年167周观测数据。SEAFI和个别航线数据反映了从上海港到东南亚基地港口的即期汇率。作者利用极坐标图分析季节性模式。在预测方面,研究采用了自回归综合移动平均(ARIMA)和季节性自回归神经网络(SNNAR)两种单变量模型。对于这两种模型,作者比较了原始水平和对数转换数据的预测结果。本研究发现,东南亚六条集装箱贸易航线的季节性模式总体上是相同的,但表现出独特的特征。ARIMA模型对一周前测试样本的预测效果优于SNNAR模型。SNNAR模型仅对选定的两条路线的4周预测提供了更好的性能。实际影响航运公司、托运人、船东和其他主要行业参与者在决策时应考虑航线层面的季节性模式。预测分析人员可以考虑在分析中使用原始水平数据而不进行对数转换。作者建议使用ARIMA模型对大多数路线进行一步和四步预测。SNNAR模型仅推荐用于上海至越南和上海至泰国航线的多步预测。原创性/价值本研究分析了一个新的航运指数,即SEAFI及其基础的六条航线。利用极坐标图分析了集装箱运价数据的季节性模式,并利用ARIMA和SNNAR模型进行了预测。此外,作者还对对数变换和非变换序列的预测性能进行了实验。

PurposeThis paper examines the changes suggested by maritime stakeholders to achieve gender equality in seafaring, a male-dominated profession.Design/methodology/approachAdopting a four-stage career cycle framework, this paper analyzes changes proposed by 423 industry stakeholders to promote gender equality in seafaring. These proposed changes were posted on the Day of Seafarers 2019 virtual wall set up by the International Maritime Organization, which served as a forum for industry stakeholders from all over the world to voice their opinions and suggestions.FindingsThe data analysis shows that the suggested changes reflect many challenges and barriers women seafarers face. While stakeholders from Organisation for Economic Co-operation and Development (OECD) countries are more likely to call for changes to remove barriers in the retention and development stage, gender equality in seafaring in non-OECD countries is still seriously hindered by barriers in the recruitment stage. The paper also reveals that comparatively male stakeholders are less likely to appreciate the problems women seafarers face.Originality/valueThis paper takes a comparative approach, comparing the changes proposed by seafarers and other industry stakeholders from different parts of the world. This approach provides a nuanced understanding of issues related to gender equality in seafaring by showing that stakeholders from different backgrounds have different priorities.
本文探讨了海事利益相关者建议的变化,以实现男性主导的航海职业中的性别平等。采用四阶段职业周期框架,本文分析了423个行业利益相关者提出的促进航海业性别平等的变化。这些拟议的变化被发布在国际海事组织设立的2019年海员日虚拟墙上,该虚拟墙上是来自世界各地的行业利益相关者发表意见和建议的论坛。数据分析表明,建议的变化反映了女海员面临的许多挑战和障碍。虽然来自经济合作与发展组织(OECD)国家的利益相关者更有可能呼吁改变以消除保留和发展阶段的障碍,但非经合组织国家的海员性别平等仍然受到招聘阶段障碍的严重阻碍。该论文还揭示,相对而言,男性利益相关者不太可能理解女性海员面临的问题。原创性/价值本文采用比较方法,比较了来自世界不同地区的海员和其他行业利益相关者提出的变化。这种方法通过显示来自不同背景的利益相关者有不同的优先事项,提供了对航海中性别平等相关问题的细致入微的理解。

In Tomoya Kawasaki, Takuma Matsuda, Yui-yip Lau and Xiaowen Fu (The durability of economic indicators in container shipping demand: a case study of East Asia–US container transport), the durability of economic indicators on container movements from East Asia to the USA are identified by a vector autoregression model using monthly-based time-series data. Takuma Matsuda, Enna Hirata and Tomoya Kawasaki aim to contribute to the empirical literature on the container shipping industry market structure (Monopoly in the container shipping market: an econometric approach). Phong Nha Nguyen and Hwayoung Kim aim to identify the characteristics of the maritime shipping network in Northeast Asia as well as compare the level of port connectivity among these container ports in the region (Analyzing the international connectivity of the major container ports in Northeast Asia).
