With space constraints onshore, strong renewable resources available far offshore and growing green hydrogen demand, far offshore green hydrogen production may be an attractive option. To assess this potential, a mixed integer quadratically constraint programming (MIQCP) optimization model was developed …

The current sea margin estimate applied in early ship design, commonly assumed 15-20% extra installed engine power, is not based on calculations, but has nonetheless become an industry standard. These sea margin estimations, applied in early ship design, are insufficiently accurate. This paper evaluates …

The energy transition from fossil fuels to sustainable alternatives makes the design of future-proof ships even more important. In the design phase of a ship, it is uncertain how many and which fuels it will use in the future due to many external factors. In fact, a ship typically sails for decades, …

The ongoing technological development of methanol energy converters (EC) towards decarbonization means that their dimensions and performance characteristics will be continually updated during the lifecycle of vessels currently designed. These advancements influence the ease of EC integration within the …

This research addresses the importance of sustainability in shipping beyond fuel selection, stressing the need for responsible material usage in vessel construction and maintenance. Transitioning to a circular economy is crucial for sustainable waste management in the industry, yet current ship design …

Inland water vessels are impacted by climate change in two respects. First of all, they will need to convert to low-impact power propulsion and energy (PPE) systems. Secondly, they will need to deal with the impact of climate change, especially longer periods of very low and high water. This paper reviews …

Shipowners need to prepare for low-emission fuel alternatives to meet the IMO 2050 goals. This is a complex problem due to conflicting objectives and a high degree of uncertainty. To help navigate this problem, this paper investigates how methods that take uncertainty into account, like robust optimization …

Deze handreiking biedt gemeenten en organisaties praktische handvatten om burgers te ondersteunen en te verleiden tot een grotere betrokkenheid bij de natuur. De handvatten lopen uiteen van faciliteren van actieve burgers met een sterke natuurbetrokkenheid tot betrekken van burgers die ver af staan van …

Dit onderzoek gaat over ‘de toepasbaarheid van een graslandmanagement programma in de Nederlandse melkveehouderij’. Agrovision biedt een graslandprogramma aan als onderdeel van een desktopprogramma voor melkveehouders. Om van het graslandmanagement programma een Cloudprogramma te maken, wil Agrovision …

Ships are a crucial link in any production supply chain and provide up to 90% of all transport. However, ships are also a major contributor to GHG emissions, local emissions and contain many hazardous materials. To change this, we need to consider the full lifespan of the vessel, including its dismantling …
