Zoutendijk, M. (author), Mitici, M.A. (author)Taxiing aircraft using electric vehicles is seen as an effective solution to meet aviation targets of climate neutrality. However, making the transition to electric taxiing operations is expected to significantly increase the electricity demand at airports. In this paper we propose a mixed-integer linear program to schedule electric vehicles...journal article 2024

Li, M. (author), Bijvoet, Bas (author), Wu, Kangjie (author), Jiang, X. (author), Negenborn, R.R. (author)Offshore wind energy is expected to be the most significant source of future electricity supply in Europe. Offshore wind farms are located far from the shores, requiring a fleet of various types of vessels to access sites when maintaining offshore wind turbines. The employment of the vessels is costly, accounting for the majority of the total...journal article 2024

Bakker, F.P. (author), van der Werff, S.E. (author), Baart, F. (author), Kirichek, Alex (author), De Jong, Sander (author), van Koningsveld, M. (author)Reducing waiting times is crucial for ports to be efficient and competitive. Important causes of waiting times are cascading interactions between realistic hydrodynamics, accessibility policies, vessel-priority rules, and detailed berth availability. The main challenges are determining the cause of waiting and finding rational solutions to...journal article 2024

Li, M. (author)Europe’s offshore wind capacity is expected to reach 450 GW by 2050, meeting 30% of Europe’s electricity demand. With the increase of installed capacity, the costs invested in O&M will also increase significantly considering O&M cost is one of the biggest contributors to life cycle costs. The improvement of O&M management for...doctoral thesis 2023

WU, KANGJIE (author)The research on sustainable energy is growing, among which, wind energy catching growing attention and the potential has been supported by more and more countries. Compared with onshore wind farms, offshore wind farms have more advantages including the abundant wind resource at the offshore location and more possible construction areas. While...master thesis 2023

A Multi-Objective Optimization Model for Offshore Wind Farm Operations & Maintenance Fleet SelectionBloothoofd, Jesse (author)Until recently, tenders in Europe were awarded to wind farm developers based on the highest auction prices or the lowest subsidized bids. The wind industry has suggested that non-price-related criteria should be considered for tenders, like plans to reduce greenhouse gas emissions. As a result of the sustainable tender criteria, greenhouse gas...master thesis 2023

Fan, Q. (author), van Essen, J.T. (author), Correia, Gonçalo (author)Shared automated vehicles (SAV) are expected to benefit the sustainable development of urban regions and alleviate the negative impacts brought by the increasing number of private cars. In this paper, we envision a future scenario where non-pooled SAVs replace private cars and provide public on-demand mobility services to satisfy the mobility...journal article 2023
