Shore power is an important green technology used by ports to reduce carbon emissions. This paper investigates how to design subsidy strategy for promoting the installation and utilization of shore power. However, while installation subsidies may promote the installation of SPI in ports, resulting in a reduction in ship emissions, utilization subsidies may attract more ship visits, which may increase the total emissions of a port. Therefore, subsidies for shore power utilization and installation should be optimized to minimize the cost to government (comprising the environmental costs of ship emissions, the cost of utilization or installation subsidies, and carbon taxes) and maximize the profit for ports (including profit from original and new ships, utilization and installation subsidies, and carbon taxes). Using the Stackelberg game methodology, we discuss five cases to give a comprehensive analysis of the design of different subsidy policies, including no subsidy, SPI-utilization subsidy undertaken by port, SPI-utilization subsidy undertaken by port and government, carbon emission tax policy considering SPI-utilization subsidy, and SPI-utilization and SPI-installation subsidies undertaken by port and government. Managerial insights are generated according to the theoretical analysis and numerical experiments results, which can give references to the government and port operators.
The present paper explores how industrial symbiosis emergence unfolds within port industrial areas through a multiple case study that focuses on actors, platforms for collaboration, and content of stakeholder processes. Drivers for industrial symbiosis emergence are identified, and future lines of research are proposed.
Port clusters are expected to play a significant role in the transition towards a circular economy, both at the level of facilitating regional and global transport within circular production chains, as well as hosting circular activities in port areas. There is strong evidence that significant investments in the circular economy (CE) are being made in port areas, albeit without much knowledge on their impacts. To ensure an efficient use of port resources in view of this transition, these impacts should be adequately monitored. Research on circular economy indicators for ports is still in an exploratory stage, characterized by an absence of in-depth research on the development of port-related circular economy indicators. This paper focuses on the development of a comprehensive set of relevant and feasible CE indicators, which aim to support port managing bodies (PMBs) as well as port stakeholders to monitor the CE transition taking place. Through multimethod qualitative research, including content analysis, focus groups, a gap analysis and a qualitative survey, an actionable list of CE 12 indicators for ports was developed. Seven of which are highly feasible and five of which have medium feasibility in terms of stakeholder relevance and ease of implementation. Findings related to (1) the overall limited CE ambition levels of PMBs and (2) the difference in the values of some indicators for different port typologies are also discussed. The value of this study for practitioners lies in providing them with an actionable set of KPIs which can support their efforts and communication related to their CE transition.
This article builds on rich empirical data following our unexpected discovery of a local practice to circumvent a stressful
and counterproductive work environment due to distrust at the Port of Tema in Ghana. Using theoretical work on networks,
trust, and humor, as well as extensive ethnographic feldwork, we found that the humorous atmosphere at the regularly
held physical berthing meetings fosters a sense of community, which enables competing professions, private companies,
and public institutions to manage their mutual distrust. In an environment where trust among competitors is unrealistic, we
argue that the objective of the performance of humor and transparency at the physical berthing meetings is the management
of distrust rather than the creation of trust. The meetings have, gradually, grown to serve as a pragmatic local stakeholder
adaptation to the challenges posed by universally perceived politicized, opaque, and corrupt business practices at the Port
of Tema and beyond. In conclusion, we posit that our empirical fndings allow us to identify the potential of and gaps in
theories about trust and humor in understanding the dynamics of coping strategies among competitors in business settings
that are characterized by unethical practices.

Two different media platforms played a key role in keeping Tema Port in Ghana afloat during the period immediately leading up to and during the three-week COVID-19 pandemic-related lockdown in late March–April of 2020. The one media platform, Eye on Port, is a weekly broadcast television show by the port’s authorities, which caters primarily to external commercial stakeholders of the port. The other platform is a closed WhatsApp forum used by stakeholders working at the operational level of the port. Both platforms served specific needs among their users, who had been restricted in their mobility but had to keep the port operational. Combining ‘scalable sociality’ with the concept of polymedia, we identify how the two media functioned to meet the different informational and conversational needs of their respective users. We argue that either medium alone could not fulfil the communicative needs necessary to keep the port operational during the early stage of the COVID-19 pandemic.
This paper studies the Quay Crane Scheduling Problem (QCSP). The QCSP determines how a number of quay cranes should be scheduled in order to service a vessel with minimum makespan. Previous work considers the QCSP to be a combinatorially hard problem. For that reason, the focus has been on developing efficient heuristics. Our study shows, however, that the QCSP is tractable in the realistic setting, where quay cranes can share the workload of bays. We introduce a novel linear time algorithm that solves the QCSP and prove its correctness.
The mission policy approach to the sustainable blue economy has identified as critical the ability to anticipate the emergence of a wide range of feasible innovations as they enter the transactional environment of organizations in the marine and maritime sector. This article contributes to that growing effort by harnessing the wisdom of the crowd and presents more than 60 crowdsourced, time-specific innovation forecasts expected to impact maritime, shipbuilding, ports, offshore wind, and ocean infrastructure. Data were collected in 2020 by the EU-funded Interreg VB PERISCOPE Project, a North Sea Region initiative to catalyze transregional innovation. The results can be used strategically to develop collaborative, transregional planning and policy for innovation based on data reflecting public expectations for the future. Years from now, this article can also act as a snapshot of public expectations at the onset of the decade.
This paper investigates the significance of ports in the energy transition (ET) and decarbonisation. Ports, being vital in energy value chains, play a critical role in curbing energy use and emissions. The paper draws from the MAGPIE project, funded by the Horizon 2020 programme, which showcases energy and digital solutions in a real-world setting. The paper focuses on sustainable initiatives in 12 European sea- and inland- ports, analysed through interviews and secondary data. Findings reveal that while many ports discuss ET, few have transformed their plans into significant actions due to technological, regulatory, and financial challenges. Three core themes emerge from the review: ET infrastructure, seagoing ships and hinterland transport, and governance. Ports need more actionable strategies for ET, with port authorities spearheading the adoption of sustainable technologies through collaboration.
This study investigates the appropriate port governance model for implementation of green port management (GPM) practices. Relying on social systems engineering principles, we propose a multi-criteria decision-making (MCDM) framework considering four port governance models and five major GPM practice indicators. We validate the MCDM framework using survey data collected from top management executives of three ports in the Indian Ocean Rim — Bangladesh, Sri Lanka and Tanzania. We compare the Analytic Network Process (ANP) method with more recently developed Best-Worst Method (BWM) in analysis of the MCDM problem of finding the right port governance model for GPM. We collect data using the ANP and BWM survey in January 2019 and August 2019, respectively, from the same respondents. While participating in the study in January 2019, the respondents did not know that they would respond to the same MCDM problem using a different model, which corresponds to a repeated measures experimental design. In both analyses, we find that increasing privatization in port governance would enhance the implementation of GPM practices. Our study furthermore suggests that BWM is a reliable MCDM method with greater applicability than ANP, as it requires significantly lower number of judgement comparisons.
