This PhD project focuses on integrated control strategy and maintenance policy design to assure reliable operation and high availability of ships powered by ammonia (NH3). Ammonia is one of the most promising hydrogen carriers and clean, alternative fuels for long-distance shipping and other maritime, or heavy-duty, applications. When produced from renewable power, ammonia could decarbonize shipping and thus help to achieve the goals of the Paris agreement to combat climate change.
In this PhD project, you will start from an innovative ammonia-fuelled power and propulsion system concept for ships utilising a combination of state-of-the-art Solid Oxide Fuel Cell (SOFC) and Internal Combustion Engine (ICE) technology, i.e., the AmmoniaDrive concept. This system contains many non-proven subsystems in new configurations introducing the scientific challenges related to system diagnosis.
The aim of this PhD project is to investigate how automatic control strategies could ensure a high ship system performance under various operating conditions. This requires input from a large number of sensors installed on the system. At the same time, this sensor data will be used to diagnose the system and predict upcoming failures. These insights will, on the one hand, be used to plan maintenance activities (e.g. repair, replace parts) just-in-time, and on the other hand to feed the control system, allowing to adapt the system operational settings (e.g. to reduce the loads on specific parts) to the actual system condition. You will investigate the operational control challenges of the ship concept, for the ship system itself, as well as in relation to the direct surrounding waterway users. The link between operational decision making (during navigation) and decision making for maintenance (typically on a somewhat longer timescale) are hereby considered from an integrated perspective. Of particular importance hereby is how to control the system in unexpected situations involving, e.g., sensor or actuator malfunctioning or unexpected movements of other waterway users.
The key challenges that we will address are:
This PhD project is hosted by the Dept. of Maritime & Transport Technology, TU Delft, and is part of the NWO AmmoniaDrive program. In this program universities and industry work together to achieve breakthroughs towards the transition towards a zero-emission maritime sector. During the project you will moreover directly interact with the researchers of the Researchlab Autonomous Shipping (RAS) at TU Delft.
Candidates for this challenging project have an MSc degree and background in systems and control engineering, maintenance & operations, mathematical modelling, maritime technology, or related areas. Good communication and writing skills in English and the ability to collaborate are important.
Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details, please check the Graduate Schools Admission Requirements.
Fixed-term contract: 4 years.
Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.
Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills.
The TU Delft offers a customisable compensation package, discounts on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation.
