de Vos, P. (author), Somers, L.M.T. (author), Tinga, T. (author), Foekema, E.M. (author), van der Zwaan, B. (author), Negenborn, R.R. (author)Several news items and short movies have appeared online recently, announcing that the AmmoniaDrive Consortium was awarded a prestigious NWO Perspectief grant. But what is the AmmoniaDrive research project? How does it contribute to combatting shipping-induced climate change? Who are in the consortium and why? And finally, what research...journal article 2022

de Vos, P. (author), de van der Schueren, T.A.R. (author), Los, S. (author), Visser, K. (author)In this paper a Concept Exploration Tool (CET) for naval ship power plants is presented. The ideas behind the CET are introduced as well as the inner workings of the tool. Objective functions for different relevant design criteria (energy efficiency, emissions, signatures, etc.) are shortly discussed, after which the results for a Frigate case...journal article 2022

Scheffers, E.L. (author), de Vos, P. (author)Reliability and survivability play a key role in the ship operation and ship design process of navy ships, but increasingly also of complex commercial vessels. These requirements prove relevant for different elements within the ship design scope, including the distribution system design of data, energy and fluid (water, fuel, oil, etc.). In...conference paper 2022

Sui, Congbiao (author), de Vos, P. (author), Stapersma, D. (author), Visser, K. (author), Hopman, J.J. (author), Ding, Yu (author)Analysis of ship propulsion system performance is often performed using detailed hydrodynamic models to assess load changes, which are subsequently compared to static engine limits, or by detailed engine models that are rarely integrated with sufficiently detailed propulsion models for load change estimation. To investigate the dynamic engine...journal article 2022

Sui, Congbiao (author), de Vos, P. (author), Hopman, J.J. (author), Visser, K. (author), Stapersma, D. (author), Ding, Yu (author)Current EEDI (Energy Efficiency Design Index) regulations striving to reduce the installed engine power on new ships for a low EEDI may lead to underpowered ships having insufficient power when operating in adverse sea conditions. In this paper, the operational safety of a low-powered ocean-going cargo ship operating in adverse sea conditions...journal article 2022

(author)The current literature on solid oxide fuel cell and internal combustion engine (SOFC-ICE) integration is focused on the application of advanced combustion technologies operating as bottoming cycles to generate a small load share. This integration approach can pose challenges for ships such as restricted dynamic capabilities and large space...journal article 2021

Habben Jansen, A.C. (author), de Vos, P. (author), Duchateau, E.A.E. (author), Stapersma, D. (author), Hopman, J.J. (author), van Oers, B.J. (author), Kana, A.A. (author)Naval ships are designed to operate and survive in hostile environments. As such, vulnerability reduction is a major topic of interest during the design of a naval ship. For modern naval ships the vulnerability is largely determined by the design and layout of distributed systems. The vulnerability of these systems needs to be assessed early on,...journal article 2020

de Vos, P. (author)The hybrid internal combustion engine-solid oxide fuel cell AmmoniaDrive concept is a single-fuel, high-efficiency, high-tech ship power/propulsion plant solution that will produce no pollutant emissions. It also strikes the right balance between different, relevant ship design considerations. Too good to be true?journal article 2020

Sapra, H.D. (author), Godjevac, M. (author), de Vos, P. (author), Van Sluijs, Wim (author), Linden, Youri (author), Visser, K. (author)With increasingly stringent emission regulations, marine natural gas engines need to improve their performance. Various proven advantages of hydrogen-natural gas (H-NG) blends make them a promising enhanced fuel solution. Although modelling of H-NG combustion has been investigated before, mostly using CFD models, the literature on the...journal article 2020

Sui, Congbiao (author), de Vos, P. (author), Stapersma, D. (author), Visser, K. (author), Ding, Yu (author)Hybrid propulsion and using liquefied natural gas (LNG) as the alternative fuel have been applied on automobiles and some small ships, but research investigating the fuel consumption and emissions over the total voyage of ocean-going cargo ships with a hybrid propulsion and different fuels is limited. This paper tries to fill the knowledge...journal article 2020

de Vos, P. (author)This research aims to help in solving problems experienced with system integration in early-stage ship and system design by enabling automated design space exploration for on-board energy distribution systems. An Automatic Topology Generation (ATG) tool is developed and tested to do so. The ATG tool supports system designers in making trade-off...doctoral thesis 2018

de Vos, P. (author), Stapersma, D. (author), Duchateau, E.A.E. (author), van Oers, B.J. (author)This paper demonstrates the usefulness of an automatic topology generator that uses genetic algorithm techniques to generate many alternative system designs and in doing so enables design space exploration for on-board energy distribution systems. This will provide better insight in the relation between design requirements (e.g. budget), system...conference paper 2018

Stapersma, D. (author), de Vos, P. (author)In this paper we describe a generic way of sizing main dimensions of primary equipment for marine applications. Contrary to a straight fit through a database the method tries to develop expressions in which, apart from the main specifications in terms of power and speed, the selection of the main machine parameters has an influence on the...conference paper 2015

de Vos, P. (author)In this paper I describe the design of a new course about ship resistance and ship propulsion system fundamentals. The occasion for designing a new course on this topic was the re-design of the Maritime Technology Bachelor of Science programme at Delft University of Technology in the Netherlands. Especially the alteration to another teaching...conference paper 2015

de Vos, P. (author)Network topology of technical systems (i.e. the way in which components of technical systems are connected to each other through connections like pipes, cables, shafts, etc.) in naval vessels is quickly fixed in current design methods. This means the vulnerability of these systems is also quickly fixed. Variation in network topology may lead to...conference paper 2014

(author)Biological treatment using Methane Oxidizing Bacteria (MOB) immobilized on carrier materials is considered as the best solution to mitigate methane emission at low concentrations (e.g., in animal houses). The porosity of the support is one of the most important factors for an efficient removal of methane. In animal houses, building materials...conference paper 2013
