Overes, P.H.P. (author), Borsje, B. W. (author), Luijendijk, Arjen (author), Hulscher, S. J.M.H. (author)Sand waves are found on shallow, sandy seabeds throughout the world and their dynamics may pose an imminent threat to offshore construction. Therefore, there is a pressing need to understand bed level dynamics in sand wave areas. These bed level dynamics lead to variations in sand wave shape and migration rate over time. However, these...journal article 2024

Van Rheenen, E.S. (author), Scheffers, E.L. (author), Zwaginga, J.J. (author), Visser, K. (author)It is essential to use alternative fuels if we are to reach the emission reduction targets set by the IMO. Hydrogen carriers are classified as zero-emission, while having a higher energy density (including packing factor) than pure hydrogen. They are often considered as safe alternative fuels. The exact definition of what safety entails is often...journal article 2023
