Zwaginga, J.J. (author), Lagemann, Benjamin (author), Erikstad, Stein Ove (author), Pruyn, J.F.J. (author)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 and stochastic optimization, could be...journal article 2024

Blokland, M. (author), van der Mei, R. D. (author), Pruyn, J.F.J. (author), Berkhout, J. (author)Piping systems are common in many architectures and designing such systems is often a complex task. Design automation of piping systems is therefore a universal research subject. Nonetheless, these piping systems are often still designed by hand as a result of their complexity. Consequently, costs associated with piping design are high,...journal article 2023

Pruyn, J.F.J. (author)In search of a way to bring back the positive aspects of an internship into the curriculum, TU Delft identified serious games as a potential solution. The literature studied showed that games could increase motivation and understanding, leading to improve knowledge retention. This paper has brought these insights together in a framework...journal article 2023

Buirma, M.I.M.J. (author), Vleugel, J (author), Pruyn, J.F.J. (author), Doedee, Vincent (author), Schott, D.L. (author)The International Maritime Organisation (IMO) calls for the maritime industry to restrict its CO2 emissions by −40% (IMO2030) and −70% (IMO2050). This paper answered the following research question: “Which technical, economic and emissions-related conditions predominantly determine the feasibility of a conceptual supply chain of liquid CO2 that...journal article 2022

Gartland, Nicolas (author), Pruyn, J.F.J. (author)The design and preliminary estimations of biomass supply chains are essential in matching energy supply to energy demand. This is especially true of novel/future fuels and technologies in large industries. In this paper, a Mixed Integer Linear Programming (MILP) model was formulated to represent biofuel supply chains across Europe for the...journal article 2022

Pruyn, J.F.J. (author), van Hassel, E.B.H.J. (author)In this paper, the possibility of adding the North Sea Route (NSR) route to the Belt and Road Initiative (BRI) is researched whereby the main aim is to determine if it is possible to set up a container service via the NSR route that could attract cargo from the existing maritime routes via Suez and the land route. In order to make the...journal article 2022

Stolper, Louis Cornelis (author), Bergsma, J.M. (author), Pruyn, J.F.J. (author)The energy transition of Dutch shipping is a complex gradual process due to the variety in vessels, cost and lifetime of assets, uncertainty, additional costs of climate-neutral alternatives and required regulatory changes. This paper aims to create a holistic overview of both the transition barriers and enablers. A focus is placed on the...journal article 2022

van der Kroft, D.F.A. (author), Pruyn, J.F.J. (author)In this study, various scenarios were developed that correspond to estimations of future biomass availability and biofuel demand from the maritime industry. These marine biofuel demand scenarios were based on the Greenhouse Gas (GHG) reduction targets of the Renewable Energy Directive II (RED II) and the International Maritime Organization (IMO)...journal article 2021

Bergsma, J.M. (author), Pruyn, J.F.J. (author), van de Kaa, G. (author)Energy transition is affecting the European maritime sector at an increasing rate. New technologies and regulations are being introduced with increasing speed. The ability to adapt to these changes is crucial for the economic success of the maritime sector. However, the sector is challenged by inertia due to its global nature and long-life...journal article 2021

Pruyn, J.F.J. (author)The EEDI is one measure to identify the energy efficiency of a vessel. Besides EEDI there are many other aspects relevant when considering the energy efficiency quality of a vessel, most based on design insights. In this paper, a set of ten relevant indicators are identified to establish the performance of the vessel and pinpoint the source of...journal article 2020

Strategic guidance based on the concept of cleaner production to improve the ship recycling industryJain, K.P. (author), Pruyn, J.F.J. (author), Hopman, J.J. (author)The implementation of international ship recycling regulations and international standards of health, safety and environment on a ship recycling yard improves environmental protection, occupational health and safety of the workers. However, it results in increased costs of the ship recycling process, which is detrimental for offering a high...journal article 2017

Jain, K.P. (author), Pruyn, J.F.J. (author), Hopman, J.J. (author)The ship owner's decision to select a recycling yard for dismantling and recycling an end-of-life ship is primarily influenced by the price offered for purchasing the ship. The recycling yards offering ‘green’ recycling services generally quote lower prices than other yards due to the higher cost of dismantling a ship by following international...journal article 2017

Jain, K.P. (author), Pruyn, J.F.J. (author), Hopman, J.J. (author)Ship recycling yards around the world offer a price to the ship owners for buying an obsolete vessel to demolish and recycle based on the ship's end-of-life weight. The offer price is mainly based on the type of ship and the estimated quantity of steel available. The steel weight estimation, in terms of percentage of lightweight (LDT), is...journal article 2016
