Location of fueling stations and routing of zero‐emission well‐boats in the Norwegian aquaculture industry

International Transactions in Operational Research, EarlyView.
Abstract We study the problem of locating hydrogen fueling stations for zero‐emission aquaculture vessels in Norway and model the problem as a location‐routing problem, considering both the location of hydrogen fueling stations and the routing of aquaculture vessels.

Vessel arrival planning with full information

International Transactions in Operational Research, EarlyView.
Abstract Planning efficiency and timely arrival of vessels is crucial to smooth operations of maritime transport networks, ensuring optimal utilization of resources and minimizing operational costs. Coordination between vessel operators and terminals has the potential to reduce costs, fuel consumption, and waiting time.

Multi‐objective maritime vessel routing with safety considerations

International Transactions in Operational Research, EarlyView.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

From External Governance to Energy Diplomacy: The European Pursuit of Green Hydrogen

JCMS: Journal of Common Market Studies, EarlyView.
Abstract Following the Russian invasion of Ukraine, the European Union (EU) and its Member States are faced with the double imperative of ensuring energy security whilst reaching decarbonisation goals. A number of authors have suggested that we are observing a geopolitical Commission that is shifting to more active ‘energy diplomacy’, as opposed to its

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

Journal of Fish Biology, EarlyView.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).
