- 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).

Demonstrating the use of urban and inland waterways – for densely populated cities and more sustainable transport
- 2017
-
Ingår i: SSPA Highlights. ; 64, s. 8-11
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Demonstrating new logistics solutions is shown to be an important step for gaining understanding of system prerequisites for commercialisation, both with regard to technical issues such as vessel design characteristics and cargo handling equipment, and social matters such as the importance of practitioner involvement and the evaluation of performance criteria. SSPA demonstrated the use of urban and inland waterways as part of two large collaboration projects: DenCity and NÖKS II. This is a promising path for the future, both for managing the trend towards more densely populated cities and for using more sustainable transport solutions.

Intressentanalys av Sveriges hamninfrastruktur
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- En välutvecklad hamninfrastruktur är en förutsättning för svenskt näringsliv såväl som för ett hållbart transportsystem. Det saknas likafullt kunskap om hur dagens hamninfrastruktur tillfredsställer samhällets behov nu och i framtiden. Med detta som bakgrund kartläggs i denna förstudie olika intressenters behov och önskemål. Vidare analyseras trender och framtida transportefterfrågan i termer av hur dessa kan komma att påverka Sveriges hamnar. Mer specifikt har tjugofyra intervjuer med hamnar, varuägare, rederier, speditörer, terminaloperatörer, hamnnära myndigheter samt regioner och kommuner genomförts. Vi har också gjort en genomgång av orsaken till den starka godsutvecklingen för sjöfart i Trafikverkets prognoser över godsvolymer år 2040 genom att titta på nedbrutna utdata och se hur dessa fördelar sig på olika varugrupper och hamnar.

Svenska hamnars roll i en cirkulär ekonomi
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- För att Sverige ska kunna nå målet om att bli ett av världens första fossilfria välfärdsländer krävs en omställning till ett fossilfritt transportsystem såväl som till en cirkulär ekonomi. Sjöfart har potential att matcha de behov som en ökad cirkulär ekonomi ställer och är ett energieffektivt trafikslag. Syftet med rapporten är att förstå hur sjöfart kan nyttjas i ökad utsträckning för att transportera cirkulära produkter och material och hur hamnen kan skapa mervärde i utveckling av cirkulära logistiklösningar. Metoderna som använts är: litteraturstudier, workshops och fallstudier. Rapporten identifierar cirkulära produkter och material med potential att lyfta sig i avfallstrappan och där det är lämpligt att nyttja sjöfart för transport i det cirkulära logistiksystemet. Det handlar om muddermassor, jordmassor, mineralavfall, träavfall, plastavfall, uttjänta däck, uttjänta textilier, sorterade och återvunna textilier, planglas, spillolja och flygaska. Hamnens roll vid hantering av cirkulära material studerades mer specifikt för massor, dissolvingmassa baserad på återvunna textilier, matrester och etanol. Det blev tydligt att hamnen kan skapa värde i form av lagring, konsolidering, lossning och lastning av containrar samt vara en logistiknod som erbjuder omlastningsmöjligheter mellan olika trafikslag. Hamnen känner till de lokala förutsättningarna för effektiva logistikupplägg och är en central kugge i nya aktörsnätverk. Rapporten redovisar även en beskrivning av två cirkulära logistiklösningar med involvering av sjöfart som utvecklats och utvärderats under projektet. Det handlar dels om en demonstration av en sjötransport med kalkstabiliserad lera, dels om framtagning av beslutsunderlag för investering av en tilltänkt sorteringsmaskin av planglas i vilket logistikupplägg från ett antal olika hamnar förslogs och miljöberäkningar genomfördes.

Konferensbidrag (refereegranskat)abstract
- PurposeExplicit descriptions of studied systems can support researchers in clarifying objects of study and motives of research as well as in structuring research design. However, since many scholars of systems approaches operate outside the field of logistics, applying systems approaches in logistics can be challenging. The purpose of this paper is therefore to describe how a systems approach can be applied in logistics so as to provide guidance for logistics researchers in their descriptions of studied systems.Design/methodology/approachTwo systems approaches were used to describe the systems studied in six doctoral theses. A series of workshops was conducted to compare the descriptions and share challenges.FindingsKey aspects for adapting the selected systems approaches corresponded to four areas of logistics—activities, flow, performance, and actors—all of which can be included in the selected systems approaches. Advice for doctoral students on applying these frameworks is provided.Research limitations/implicationsThis research can provide support to other logistics researchers when applying systems approaches and developing explicit descriptions of studied systems.Original/valueSystems approaches are central to logistics research, a field in which scholars are encouraged to apply well-known systems approaches. This paper contributes value by providing explicit examples of how such approaches were applied in six logistics research projects.
