Aarhus University, DCE - Danish Centre for Environment and Energy, has prepared an overall assessment of the potential environmental impacts from a major release or spill of ammonia in relation to production and transportation of ammonia in a PtX plant or by shipping in Greenland. Three sites were included in the assessment: Kangerlussuaq (Sdr. Strømfjord), Kangerlussuatsiaq (Evighedsfjorden) and Nuup Kangerlua (Godthåbsfjorden). The overall findings shows that a large, worst-case ammonia spill could cause severe toxic damage to organisms during the passage of the ammonia cloud from within a few km to possibly more than 10 km from the source. This could lead to local loss of animal and plant abundance for some years. However, the ammonia will be quickly diluted and degraded and will not be transferred in the food web, and the mortality will not seriously impact plant and animal populations at a regional scale. There could be a fertilising effect of ammonia on the nutrient-poor terrestrial environment lasting for some years.

We present a solution method for the liner shipping network design problem which is a core strategic planning problem faced by container carriers. We propose the first practical algorithm which explicitly handles transshipment time limits for all demands. Individual sailing speeds at each service leg are used to balance sailings speed against operational costs, hence ensuring that the found network is competitive on both transit time and cost. We present a matheuristic for the problem where a MIP is used to select which ports should be inserted or removed on a route. Computational results are presented showing very promising results for realistic global liner shipping networks. Due to a number of algorithmic enhancements, the obtained solutions can be found within the same time frame as used by previous algorithms not handling time constraints. Furthermore we present a sensitivity analysis on fluctuations in bunker price which confirms the applicability of the algorithm.
We introduce a decision support tool for liner shipping companies to optimally determine the sailing speed and needed fleet for a global network. As a novelty we incorporate cargo routing decisions with tight transit time restrictions on each container such that we get a realistic picture of the utilization of the network. Furthermore, we show that it is possible to extend the model to include optimal time scheduling decisions such that the time associated with transshipments is also reflected accurately. To solve the speed optimization problem we propose an exact algorithm based on Benders decomposition and column generation that exploits the separability of the problem. Computational results show that the method is applicable to liner shipping networks of realistic size and that it is important to incorporate cargo routing decisions when optimizing speed.
Projektet gennemfører en antropologisk analyse af forholdet mellem a) smarte teknologier (fx automation, smarte algoritmer eller drone- og vision-teknologier) b) fagpersoner ombord ifm. navigation) c) fagpersoner og beslutningstagere i rederiorganisation (som bestillere af ny teknologi) og d) udviklervirksomhederne (som designere af fremtidens løsninger) for at afklare, hvilke ikke-tekniske aspekter, der skal tages højde for og hvilke nye samarbejdsformer, der er behov for, og hvordan disse understøttes organisatorisk, når nærmeste ’kollega’ for fagpersonerne ombord bliver en robot eller en automatiseret teknologi. Fokus i projektet vil være på, hvordan samarbejdet mellem medarbejder/leder og robot/drone/teknologi skal/kan organiseres, samt hvordan de nye typer ’kolleger’ vil påvirke organiseringen af samarbejdet.
What Is the Issue?
Sustaining long-term growth requires marine suppliers to define their pricing strategies in a holistic fashion. However, pricing is an under-managed activity in many companies. Especially when moving towards servitization, services or integrated solutions are frequently underpriced or promised at performance levels that cannot be delivered profitably.
Why Is It Important?
Pricing is one of the most important elements for all business and everything in the business works to justify the input value for a price and turn it into a profit. It therefore has a dramatic but frequently underappreciated effort on achieving profitability and keeping business thriving.
What Can Be Done?
The marine supplies industry needs radical change in pricing by thinking about customer’s needs and aligning the incentives between suppliers and customers for long-term relationship. Value-based pricing is the way forward. An intensive discussion has been made with regard to the key challenges of applying value-based pricing in the marine supplies industry. Understanding these challenges is crucial for a move towards value-based pricing and will shed light on how to tackle these challenges.
This report presents both the quantitative and qualitative results of a study on bullying and harassment in the Danish merchant fleet. The Minister for Industry, Business and Financial Affairs asked the
Danish Maritime Authority to conduct an external study of the extent of bullying and harassment among seafarers on Danish vessels. This task was assigned to the Centre of Maritime Health and Society at the University of Southern Denmark. The Commission for the study (in Danish) may be found on the Ministry of Industry, Business and Financial Affairs website. The report consists of seven chapters, and only the results are presented, by request from the Danish Maritime Authority. An English “Literature review” is made in a separate annex, with an analysis of other international research studies within the area of bullying and harassment. This has been requested by the Danish Maritime Authority. It is permitted to quote the results in the report on the condition that the University of Southern Denmark and the Centre of Maritime Health and Society is credited as the source.
The cybersecurity landscape is evolving, driven by a reinforcing feedback loop of increasingly sophisticated attacks and defences. Threat actors, long benefitting from the asymmetrical “attacker’s advantage” of focused targeting, have now matured their organizational structures to facilitate tactical information sharing, technique specialization, the establishment of markets for buying and selling exploit and vulnerability information, and providing training on how to circumvent detection and defence systems.
Denne guide indeholder 8 anbefalinger til, hvordan
den grønne omstilling i Det Blå Danmark kan understøttes. Guiden er baseret på tre forskningsrapporter
fra DPU, Aarhus Universitet udarbejdet med støtte
fra Den Danske Maritime Fond i årene 2019-2022. I
rapporterne kan du læse mere om baggrunden for
anbefalingerne. Ud over anbefalingerne indeholder
guiden også refleksioner fra repræsentanter fra Det
Blå Danmark. Guiden er lavet til dig, der arbejder
med grøn omstilling; uanset om det er som udstyrsproducent, i rederierne, på skibene eller for en offentlig organisation.
I søfart handler den grønne omstilling om en række
nye tekniske løsninger, eksempelvis nye drivmidler
til skibe og nye digitale teknologier. Men den er
mere end det. Den involverer også nye måder at organisere sig på og et nyt ’mindset’, dvs. nye måder
at tænke drift og vækst på. Formålet med den ene
af rapporterne – “Grøn omstilling i det Blå DanmarkVærdier og normer for handling”— var således at
kvalificere arbejdet med den grønne omstilling
ved at kortlægge de ord, som aktørerne i Det Blå
Danmark beskriver den grønne omstilling med, de
nye typer organisering, som omstillingen kalder på,
samt de ofte oversete kulturelle og sociale betingelser, der står i vejen for eller bidrager til den grønne
omstilling.
