De Kwant, Jochem (author), Hekkenberg, R.G. (author), Souflis-Rigas, A.S.R. (author), Kana, A.A. (author)This article examines the potential implications of using iron powder as an alternative fuel on the design and performance of container ships. Iron powder is a relatively new alternative energy carrier and one in which little research has been done into the application on-board vessels as part of the maritime energy transition. The key...journal article 2023

Jiang, M. (author), Baart, F. (author), Visser, K. (author), Hekkenberg, R.G. (author), van Koningsveld, M. (author)The availability of supporting bunker infrastructure for zero-emission energy sources will be key to accommodate zero-emission inland waterway transport (IWT). However, it remains unclear which (mix of) zero-emission energy sources to prepare for, and how to plan the bunker infrastructure in relative positions and required capacity at corridor...conference paper 2023

Colling, A.P. (author), Hekkenberg, R.G. (author), van Hassel, E.B.H.J. (author), Vidić, M. (author), Bačkalov, I. (author)Objective: This study investigates the implementation of the waterborne platooning transport concept in two of the largest European inland navigation corridors, the Rhine and the Danube region. Each region has different geo-economic and environmental features. These features are compared, and their effects on implementing a waterborne...journal article 2022

de Vos, J. (author), Pruyn, J.F.J. (author), Hekkenberg, R.G. (author)Autonomous ships have become a topic of interest for an increasing number of researchers over the last few years. Most of the research that is being performed focuses on autonomous navigation. An important driver for this research is the belief that autonomous navigation will increase safety at sea. In order to evaluate the possible safety...conference paper 2022

Colling, A.P. (author), van Delft, Y. (author), Peeten, V.P.M. (author), Verbist, T. (author), Wouters, S. (author), Hekkenberg, R.G. (author)A waterborne platooning concept, i.e. a Vessel Train (VT) it is composed of a fully manned lead vessel that takes over navigational responsibility for the followers. Joining a VT helps improve the competitiveness of smaller vessels and increase their use, as it allows a vessel to sail continuously with a small crew. This paper identifies the...conference paper 2021

Kooij, C. (author), Hekkenberg, R.G. (author)Autonomous and unmanned shipping are currently hot topics in the maritime industry. However, there are many different views on how the ultimate goal of an unmanned, autonomous ship will be reached. On any given ship, a large range of tasks is performed every day, each of which need to be replaced in such a way that no human presence is...journal article 2021

de Vos, J. (author), Hekkenberg, R.G. (author), Valdez Banda, Osiris A. (author)The advent of autonomous ships that are unmanned or low-manned will reduce the number of people at risk at sea. Even when autonomous navigation does not reduce the number of accidents, this means that safety at sea will increase. In fact, increased safety is one of the primary perceived drivers for autonomous shipping, although this safety...journal article 2021

Colling, A.P. (author), Hekkenberg, R.G. (author), Can Hassel, Edwin (author)To achieve a modal shift towards waterborne transport and to deal with the shortage of crewmembers, a platooning concept called the “Vessel Train” is explored for the inland navigation sector. A Vessel Train consists of a lead and various follower vessels. The lead vessel is fully manned and takes over the navigational and situational...journal article 2021

Lu, Suli (author), Liu, Jialun (author), Hekkenberg, R.G. (author)A good mesh is a prerequisite for achieving reliable results from Computational Fluid Dynamics (CFD) calculations. Mesh properties include mesh types, computational domain sizes, and node distributions. However, in literature, we found no clear consensus about what these properties should be. In this article, we performed a case study on ship...journal article 2021

Kooij, C. (author), Kana, A.A. (author), Hekkenberg, R.G. (author)While successful trials for autonomously navigating ships have been conducted, commercially available unmanned cargo ships are currently unavailable. However, there are many solutions available that will allow for low-manned ship concepts long before fully unmanned ships are possible. There are many drivers for low-manned and unmanned...journal article 2021

van Veldhuizen, B.N. (author), Hekkenberg, R.G. (author), Codiglia, Luca (author)Global endeavors to reduce emissions in the shipping industry are accelerating the interest in fuel cell system. This paper explores the application of different fuel cell types (LT-PEMFC, HT-PEMFC and SOFC) in combination with different fuels (LH2, LNG, MeOH and NH3) in expedition cruise ships. The goal of this paper is to evaluate the impact...conference paper 2020

Boertz, C. (author), Hekkenberg, R.G. (author), van der Kolk, Richard (author)Fuel cell systems require a better early-stage prediction of the energy consumption of a ship because they are more expensive, more voluminous and less able to deal with rapid load changes than conventional diesel-powered systems. This paper discusses a model for such an improved prediction of the total energy demand of an expedition cruise...conference paper 2020

Kooij, C. (author), Hekkenberg, R.G. (author)Recently, autonomous ships have gotten a lot more attention both in the media and in research. However, very little research has focussed on the effects of automation on the size of the crew. This paper analyses the effects of added automation on the required size and composition of the crew on a 750 TEU short sea container vessel. A Crew...journal article 2020

Colling, A.P. (author), Hekkenberg, R.G. (author)The potential to implement the concept of waterborne platooning in the European short sea transportation system is currently being explored. In the concept, a platoon is referred to as a “Vessel Train” (VT). A VT is composed of a fully manned lead vessel and a number of follower vessels. The lead vessel takes over the navigational and...journal article 2020

de Vos, J. (author), Hekkenberg, R.G. (author), Koelman, H.J. (author)In recent years, a significant amount of research has been conducted on autonomous ships. Since it is assumed that these ships will sail with a significantly reduced crew or even without people on board, the design of the ship needs reconsideration. The absence of people on board and the associated safety measures could result in a more...journal article 2020

Zeng, Q. (author), Hekkenberg, R.G. (author), Thill, C.H. (author), Hopman, J.J. (author)The conventional extrapolation of ship resistance from model tests to full scale presumes that the coefficient of wave-making resistance (C<sub>w</sub>) depends on the Froude number only. This leads to the assumption that C<sub>w</sub> of a ship is identical to C<sub>w</sub> of its scaled model. However, this assumption is challenged in...journal article 2020

Low water depth has a major impact on the loading capacity of inland ships, and as a consequence on the transport capacity of the overall waterborne supply chain.
