Shipowners must constantly maintain and repair the structure, engine and marine equipment of ships to ensure their seaworthiness. All these rely on the assistance of ship classification societies (CLASSs). With their reputation of fairness and profession, CLASSs offer ship surveys and audits to assist shipowners in safely managing their ships. CLASSs also follow current and future shipping development trends and provide international maritime organizations (IMO) and flag states (FLAGs) with information to safely operate ships in an environmentally friendly manner, thereby fulfilling their social responsibility to protect those at sea and the marine environment. This study utilized the decision-making trial and evaluation laboratory (DEMATEL) method to assess of criteria of CLASSs and also investigated the practices of Taiwanese shipowners. The results revealed that the top three criteria shipowners considered when assessing CLASSs were emergency technical support service and timely response to accidents, membership in international association of classification societies (IACS), and surveyors’ adherence to the boarding schedule. A causal relationship diagram indicated CLASS technical ability as a cause dimension and shipowner operation cost as an effect dimension.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"50 1","pages":"980 - 1004"},"PeriodicalIF":3.5,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47776893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper first collects bilateral trade data of 16 categories of major commodities among 55 countries along the B&R for 2017. Second, according to current and future transportation accessibility, this paper constructs two types of topological networks among countries along the B&R from the perspectives of both competitive and complementary trade. Percolation theory is adopted to analyze the manufacturing diffusion trends and bottleneck links among the two types of topological trade networks, which provides a new perspective through which to study manufacturing relocation and diffusion patterns. The results show that (1) based on current transportation accessibility, main industries percolate and agglomerate among countries with rapid economic development along the 21st Century Maritime Silk Road and that (2) the improvement in the China-Europe Railway Express (CR Express) postpones diffusion trends and improves the relocation potential of Silk Road Economic Belt regions.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"49 1","pages":"716 - 736"},"PeriodicalIF":3.5,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47690980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such emerging concept describes a future state of the port that is adapted to these challenges. A smart port is a port that optimizes in-, intra- and outbound flow of goods and information, leads sustainable development and guarantees safe, resilient and secure activities through the capabilities of its (extended) port community and enabling technologies. However, turning a traditional port into a smart port is a strategic challenge for the port community at large. To contribute to this practically relevant and academic challenge, the present paper applies a literature review and the novel maturity model development methodology to develop a strategic tool. This newly-developed strategic tool (i) enhances the common understanding of the current and aspired maturity state, (ii) support decision-making of port policy and management actors and (iii) represent a maturation path for improvement for port communities. The case study results demonstrate the benefits and relevance of the tool. Finally, recommendations are made to apply this policy tool for digitalization strategy.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"50 1","pages":"447 - 465"},"PeriodicalIF":3.5,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44468281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, the development of information technology has inspired VOCCs to establish online booking platforms, which has changed the traditional booking behavior of shippers. Thus, this paper investigates the equilibriums of platform encroachment and information sharing with two symmetric VOCCs and a forwarder. Using a game-theoretic model, it can be characterized as Stackelberg-Nash game with Bertrand competition to determine whether to encroach existing freight forwarding market and share information or not. We observe whether freight forwarder shared information is affected by the encroachment strategy of VOCCs and the market demand state. Further, the encroachment strategy can prompt freight forwarder to share information with VOCCs if the magnitude of high demand is lower. In addition, for VOCCs, the best chance of establishing online platforms is when the magnitude of high demand is relatively low, not when the demand state has increased.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"50 1","pages":"321 - 334"},"PeriodicalIF":3.5,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49669284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It creates a framework connecting weather observations with shipping operational parameters: travel speed, travel time, travel distance, the necessity of icebreaker escort. It is based on the A* algorithm, the Arctic Ice Regime Shipping System (AIRSS) methodology, and empirical relationships between ship’s speed and environmental data. The idea is to minimize travel time since sailing through areas with severe weather conditions requires speed reduction. The objective function finds the fastest safe path with minimal icebreaker escort. We used 2019–2020 environmental data to test the algorithm and analyzed daily optimal NSR transit routes for Eastbound and Westbound directions. It was shown that environmental parameters significantly affect the vessel’s path, while ice parameters make the largest contribution. Depending on the ship’s ice class and sailing season, it takes between 11 and 38 days to complete the entire route. All obtained operational parameters are valuable for assessing transportation costs, profitability, and riskiness of NSR. We provide their seasonal, monthly, and weekly values, and statistical parameters.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"50 1","pages":"924 - 940"},"PeriodicalIF":3.5,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44070016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vessel movement information of 3,957 container ships from March 2017 to April 2017 is included. The world top 20 container ports’ berth and anchorage areas are identified through Density Based Spatial Clustering of Applications with Noise (DBSCAN) and convex hull methods, and their hourly port congestion statuses are depicted in terms of the traffic volume and turnaround time. The constructed congestion measures overcome the disadvantages of the traditionally used port or industry data, which is heterogenous, behind the time and not easy to obtain publicly. The higher frequency (hourly) of the proposed measures can effectively monitor any slight change in port performance. A Long Short-Term Memory (LSTM) neural network model is then proposed for congestion prediction using constructed congestion measures. Point prediction and sequence prediction are both performed. We innovatively introduce congestion propagation effects into the prediction model as input features. Using Shanghai, Singapore and Ningbo ports as case studies, results show that the inclusion of congestion propagation effect can improve the prediction performance especially for sequence prediction. This study provides significant implications and decision support for container shipping market participants.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"50 1","pages":"835 - 860"},"PeriodicalIF":3.5,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46090884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, although central international ports, which are legally ranked second, have important roles to play in trade with Asia, it is difficult to expand the functions of these ports further without the development of strategic measures, given the government policies and accompanying budget constraints. This paper describes an examination of the feasibility of logistics strategies for a second-rank port to become a hub for Asia in Japan consistent with the current policy by using the global logistics intermodal network simulation, considering Hakata Port as a case study. The results show that Hakata Port has the potential to collect cargo from ports on the Japan Sea side and to launch shuttle services to Southeast Asia. The simulation results also suggest that cooperation with Kitakyushu Port, which is geographically close, is desirable. Approaches based on the characteristics of port governance in Japan are also presented.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"50 1","pages":"707 - 723"},"PeriodicalIF":3.5,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42904730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes an analytic approach to quantify narrow waterway systems’ resiliency during disasters. First, metrics are introduced to quantify the resiliency before, during, and after a disruption. The existing Key Performance Indicators (KPIs) for Maritime Transportation Systems (MTS) are examined, and two metrics, 1) the number of inbound and outbound vessels and 2) Total Stopped Vessel-Hours, are selected to measure the resiliency of a waterway system. Second, a heuristic method is developed to derive the KPIs from the Automatic Identification System (AIS) data. Finally, the proposed methodology is performed for the Houston Ship Channel (HSC) AIS data before, during, and after Hurricane Harvey, in August 2017. The results are presented for the entire channel and highlight useful information about the performance of individual docks, terminals, and waterway zones within HSC. This study helps decision-makers identify the weaknesses and potential bottlenecks in a waterway confronting a disruption and come up with remedies.","PeriodicalId":18288,"journal":{"name":"Maritime Policy & Management","volume":"50 1","pages":"797 - 817"},"PeriodicalIF":3.5,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46214971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
