SeaCharging - Investigating the Need for Standardised Charging Infrastructure for Maritime Electrified Vessels
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The transport sector, including maritime transport, is facing accelerating electrification, where it is important that charging infrastructure is developed in parallel with electrified vessels. In today's few examples, charging technology is adapted to specific vessels and conditions. The possibility of using standards and standardisation to increase the efficiency of introducing electrified vessels has been the focus of the SeaCharging project. The middle segment of ships, such as waterborne public transport, is facing a rapid increase in electrification. The project begins with an exploratory analysis of the current situation with charging stations in Sweden. This analysis covers the obstacles, needs and opportunities in different shipping segments and geographical areas. This results in an informative review providing input to standardisation committees, but also ports and shipping companies. Dissemination of the project’s results was achieved via a workshop, a number of seminars and this final report directed at the maritime, energy, technology, and standardisation communities. Together with Lighthouse, we will in early 2023, do a broad workshop for the whole sector, presenting the final project results and putting them into a wider context.

International container shipping through the Covid-19 pandemic - Disruptions from a Swedish perspective
- 2024
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- At the onset of the pandemic in spring 2020, the Swedish shipping sector was first affected by border closures preventing passengers to use RoPax shipping and cruise ferries. There were some blank sailings but in general they kept operating to foster intra-European trade by trucks despite the missing revenues from passengers. Shipping in general was affected by port disruptions and complicated crew changes. Eventually, however, it was clear that the most dramatic disruptions on a global scale where experienced in the container segment. General media reported on delayed goods, high freight rates and, however not related to the pandemic, the Ever Given blocking the Suez Canal for a week in March 2021. Currently, there are few reports of supply chains and shipping suffering from disruptions and capacity constraints related to the pandemic. The peak in freight rates was rather replaced by depressed rates and there is a certain risk that some logisticians and supply chain managers regard the pandemic as a once-in-a-lifetime event and just want to get back to a previous behaviour seeing container shipping as a commodity with indefinite capacity at a reasonable price. Nevertheless, the war in Ukraine, the drought in the Panama Canal and the attacks by the Houthi rebels in the Red Sea create other problems for container shipping. Freight rates increase significantly, but from very low levels. The purpose of the report is to describe and analyse how international container shipping was affected by the Covid-19 pandemic and other disruptions. The analysis takes a Swedish perspective on disruptions and tries to go beyond the anecdotal reporting and capture what happened and why. Container shipping is put into a context of economy, consumption, world trade, supply chains and logistics. The pandemic and more current events affecting container shipping market are described together with how shipping lines responded. A series of interviews with Swedish actors revealed how they perceived the disruptions and what countermeasures the actors have applied to mitigate the effects, their organisational learning and how they prepare for future disruptions.

Assessing the eco-efficiency benefits of empty container repositioning strategies via dry ports
- 2023
-
Ingår i: Transportation Research Part D. - : Elsevier Ltd. - 1361-9209 .- 1879-2340. ; 120
-
Tidskriftsartikel (refereegranskat)abstract
- Trade imbalances and global disturbances generate mismatches in the supply and demand of empty containers (ECs) that elevate the need for empty container repositioning (ECR). This research investigated dry ports as a potential means to minimize EC movements, and thus reduce costs and emissions. We assessed the environmental and economic effects of two ECR strategies via dry ports—street turns and extended free temporary storage—considering different scenarios of collaboration between shipping lines with different levels of container substitution. A multi-paradigm simulation combined agent-based and discrete-event modelling to represent flows and estimate kilometers travelled, CO2 emissions, and costs resulting from combinations of ECR strategies and scenarios. Full ownership container substitution combined with extended free temporary storage at the dry port (FTDP) most improved ECR metrics, despite implementation challenges. Our results may be instrumental in increasing shipping lines’ collaboration while reducing environmental impacts in up to 32 % of the inland ECR emissions. © 2023 The Author(s)

Connecting vessels to shoreside electricity in Sweden
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of the KAJ-EL project was to offer decision support to ports and shipping companies about the implementation and use of shoreside electricity in Swedish ports. More specifically, this project investigated the following, among other questions related to shore power: • the driving forces and barriers among ports and shipping companies to offer or use shore power; • the decision making, steps and actors involved in the process of adopting shore power; • the costs and business arrangements for installing and operating shore power; • the challenges in the installation and operation of shore power; • the different shore power equipment used in Swedish ports and on board vessels; • the actions and condition to realise OPS adoption to a larger extent. The project group included researchers and experts in shipping, transport, logistics, economics, and human factors from SSPA and the University of Gothenburg, and included industry partners Svensk Sjöfart (Swedish Ship Owners’ Association) and Sveriges Hamnar (Ports of Sweden). In addition, industry and authorities were involved in a reference group with representatives from shipping companies, ports and electricity providers. Interviews were performed with various ports in Sweden, a port in Norway (Kristiansand) as well as the US ports of Long Beach and Seattle to compare the perspectives. Shipping companies were interviewed, as were a number of OPS equipment manufacturers, national grid operators and electricity providers. Two workshops and a final seminar were also conducted. This report presents an overview of the OPS situation in Sweden and provides principles for business models as well as recommendations for ports’ and shipping companies’ OPS work. It can be noted that Sweden is at the European forefront of OPS in the sense that it currently has nine cities offering OPS, with main focus so far on the ro-pax and ferry segment. Actors, in particular ports, perceive that the regulatory pressure to offer OPS is increasing and the knowledge about OPS, especially among non-experienced ports, is still limited. Further guidance on OPS installations and operations is therefore needed, in terms of the financial, business, technical and operational issues that the actors must deal with. One major question is how to secure the electricity supply to the ports. Collaboration between actors is key to successful OPS implementation and a higher level of standardisation can facilitate technical choices. Several areas in need of further research are highlighted in this report, such as investigating possible future power demand scenarios from using OPS, and supply strategies for ports. The project received funding from Trafikverket (The Swedish Transport Administration).

Comparing flexibility-based measures during different disruptions: evidence from maritime supply chains
- 2024
-
Ingår i: International Journal of Physical Distribution & Logistics Management. - : Emerald Publishing. - 0960-0035 .- 1758-664X. ; 54:2, s. 163-191

Tidskriftsartikel (refereegranskat)abstract
- This paper’s purpose is to explore flexibility-based countermeasures that enable actors in maritime supply chains to mitigate the effects of disruptions with different characteristics. Semi-structured interviews were conducted with shipping lines, shippers, forwarders and ports. Data on the COVID-19 pandemic’s effects and countermeasures were collected and compared with data regarding the 2016–2017 Gothenburg port conflict. Spatial, capacity, service and temporal flexibility emerged as the primary countermeasures, whilst important characteristics of disruptions were geographical spread, duration, uncertainty, criticality, the element of surprise and intensity. Spatial flexibility was exercised in both disruptions by switching to alternative ports. During the COVID-19 pandemic, ensuring capacity flexibility included first removing and then adding vessels. Shipping lines exercising service flexibility prioritised certain cargo, which made the spot market uncertain and reduced flexibility for forwarders, importers and exporters that changed carriers or traffic modes. Experience with disruptions meant less surprise and better preparation for spatial flexibility. Comparing flexibility-based measures in a pandemic versus port conflict provides insights into the important characteristics of disruptions and the relevance of mitigation strategies. The resilience of maritime supply chains, although underexamined compared with manufacturing supply chains, is essential for maintaining global supply chain flows.

Modal shift to inland waterways: dealing with barriers in two Swedish cases
- 2020
-
Ingår i: International Journal of Logistics Research and Applications. - : Informa UK Limited. - 1367-5567 .- 1469-848X. ; 23:2, s. 195-210
-
Tidskriftsartikel (refereegranskat)abstract
- This paper analyses strategies to overcome barriers to a modal shift to inland waterway transport (IWT). Barriers identified in research literature have been categorised as regulatory, financial, service quality and market characteristics. Using two cases involving Swedish entrepreneurs initiating IWT, this paper has shown how barriers to the modal shift to IWT can be managed where markets are limited. Modal shift involves multiple actors, and the entrepreneurs interacted with ports, shippers, shipping companies, regulatory actors, forwarders and hauliers, depending on the barrier. Strategies to manage barriers included negotiating, educating stakeholders, securing volumes, conducting a proof-of-concept run and identifying business opportunities for stakeholders. The findings can increase stakeholders’ knowledge of IWT. Policy makers aiming to promote modal shift must understand that fees and legislation act as barriers.

Supply chain disruptions : flexibility measures when encountering capacity problems in a port conflict
- 2022
-
Ingår i: The International Journal of Logistics Management. - : Emerald Group Holdings Ltd.. - 0957-4093. ; 33:2, s. 567-589
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose: There can be many negative effects from a disruption in a central node of companies' supply chains, such as a port conflict that reduces capacity. Strategies for disruption management include flexibility and redundancy. This paper aims to analyse a supply chain disruption from flexibility and capacity perspectives. Design/methodology/approach: A case study was conducted of the supply chain disruption caused by the port conflict in 2016–2017 in Gothenburg, in which the port operated at a reduced capacity. Companies importing and exporting goods, freight forwarders, hauliers, train operators, ports, shipping companies and their agents were interviewed. Findings: Various capacity problems (ports, links, container chassis, empty containers) were encountered due to the port conflict. Flexibility measures such as node, mode and fleet flexibility can be used in response to changes in capacity. Difficulties with applying flexibility are discussed. Research limitations/implications: Although based on a Swedish case, findings are relevant for disruptions or other types of disturbances in ports elsewhere and also in other important nodes in companies' supply chains. Practical implications: Actors influenced by disturbances in a port can increase their understanding of potential capacity problems and flexibility measures. Readiness and timely action are important due to competition regarding capacity. Originality/value: The implications on the transport network surrounding a port, including many actors, are explained, illustrating how capacity problems propagate, but there is some flexibility to manage the problems.

The influence of power and trust on the initiation and duration of modal shift solutions
- 2021
-
Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 13:7

Tidskriftsartikel (refereegranskat)abstract
- Modal shift to more energy-efficient alternatives, such as from road to rail or sea, is one path to reduce negative environmental effects. Transport providers and shippers have crucial roles in modal choice decisions, and a better understanding of the influence of interorganisational factors on modal shift is needed. The purpose is to increase the understanding of opportunities for modal shifts by exploring the influence of power and trust at the interface between transport providers and shippers. Aspects of power (coercive, reward, legitimate, expert and referent) and trust (con-tractual, competence and goodwill) influencing modal shifts were identified from interviews with shippers and transport providers in Sweden. During the initiation phase of modal shift, power ap-pears more important, while trust is shown essential for the duration. By proactively suggesting modal shift, transport providers can use expert power to create rewards and referent power, through recognition of their expertise. Building trust, particularly goodwill trust, such as time in-vested in understanding the other party, transparency about challenges and jointly seeking solu-tions, is key to establish long-term modal shifts. This paper contributes to modal shift literature with insights on power balances and trust between transport providers and shippers. © 2021 by the authors.

Ways to achieve an increased use of inland water-way transport
- 2020
-
Ingår i: 32nd Annual Conference for Nordic Researchers in Logistics (NOFOMA), Reykjavik/Online, 17-18 September.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Although a modal shift from road to water is a prioritised strategy outlined on member state and European Union levels, inland waterways are underutilised in large parts of the EU, while other areas face a challenge of competing with attractive road solutions. Thereby, there is a large potential in developing tools facilitating an increased usage of inland waterway transport. The purpose is to identify and structure key activities by various actors to realise modal shift to inland waterways. A multiple case study approach was applied, including five cases in the North Sea Region. To capture key activities, workshops, interviews and field observations were conducted. Activities to realise a modal shift was categorised according to four principal and two integrated cross-cutting themes. The process varies between actors and cases in terms of order, level of parallel tasks, number of iterations etc. Different actors can have a leading role in the modal shift process. Realisation of large-scale modal shift requires multi-actor engagement, openness for emergent solutions as well as long-term endurance. Further research could include examples outside the North Sea region. Both industrial actors and governmental organisations can apply the outlined activities. The principal and integrated themes are important to consider, and the activities described can be used as a toolbox, applicable depending on prerequisites in different situations. Earlier studies have described various barriers for a modal shift to IWT. This paper focuses on activities to realise a modal shift. A conceptual model is proposed, drawing from practice in five countries.

Drivers and Barriers for Inland Waterway Transportation
- 2020
-
Ingår i: Operations and Supply Chain Management. - : OSCM Forum. - 1979-3561 .- 2579-9363. ; 13:4, s. 406-417

Tidskriftsartikel (refereegranskat)abstract
- Inland waterway transportation (IWT) in Sweden could be a substitute for road transports with the prospects of improving the environmental performance. Sweden currently has no systematic strategies or policies for transports on inland waterways (IWW), and despite available capacity the waterways are barely utilized. In the Netherlands, for example, the IWW capacity is embedded in the transport system and utilized to a large extent. For a successful modal shift it is important to understand the drivers and barriers for the shift and develop strategies to leverage the drivers and mitigate the barriers. This study aims to identify drivers and barriers for IWT based on successful benchmark cases in the Netherlands. Furthermore, based on the learning from these benchmarks the study aims to point out strategic actions for Sweden regarding IWT. The data for this study was collected from IWT organizations, shippers and local administrations in the Netherlands. The results showed that main drivers for IWT are congestion relief, cost reduction and lower environmental impact. On the other hand, main barriers are slow pace of development, high investment costs and poor hinterland connectivity. For a successful modal shift in Sweden, it is crucial to prepare governmental support, a change in stakeholders’ mindset, decisive attitude to modal shift process and a strong long-term perspective.
