Decarbonisation of transport including the maritime sector is an integral part of the UK Government “The Ten Point Plan for a Green Industrial Revolution” and “UK Hydrogen Strategy” both set plans for an accelerated transition to sustainable transport. The PhD project will review the existing knowledge on safety design and operations of hydrogen systems and infrastructure in the maritime sector. The IGF Code (International Code of Safety for Ships Using Gases) provides the regulatory framework for the adaptation of low-flashpoint marine fuels like hydrogen. The finalization of the Fuel Cells Interim Guidelines is foreseen in 2021. No work to cover storage of hydrogen as a fuel has been initiated in IMO.
According to the IGF Code Part A, a low-flashpoint fuel like hydrogen is allowed as long as the Alternative Design approach demonstrates that the hydrogen-specific systems are as safe, reliable, and dependable as new and comparable conventional oil-fuelled ships. IGF Code Part A details requirements for risk assessments and analysis of explosion consequences to ensure that the necessary assessments are carried out to eliminate or mitigate adverse effects on people on board, the environment, or the ship.
This doctoral study will close essential knowledge gaps and contribute to the IGF Code and relevant documents (IMO CCC7/3. (2020); IMO MSC.1/Circ.1455; IMO MSC.1/Circ.1212/ Rev.1) by addressing the following issues: hydrogen containment, hydrogen bunkering systems, fuel cell and power generation safety, ventilation, control and monitoring, etc.
The study will formulate requirements to the ventilation system to control “standard” and unscheduled releases below the regulated level for initiation of alarm and protection system. The double-wall requirement for fuel lines will be analysed and new requirements will be formulated accounting for hydrogen properties. The engineering solutions to mitigate the pressure peaking phenomenon (specific only for hydrogen) will be developed. Interaction of hydrogen jet fires with vessel structure will be studied and mitigation measures suggested. Mitigation of non-uniform hydrogen deflagrations by limiting the released inventory and venting technique in vessel enclosures will be proposed, etc. Bunkering is another area where knowledge gaps to be closed, including the fuelling protocols.
The candidate will develop a structured approach to hazard identification, the definition of incident scenarios and performing hydrogen safety engineering to quantify incident consequences and estimate associated risks. Innovative safety strategies and engineering solutions will be developed to keep the risk of hydrogen-driven marine vessels at the level of current vessels or below.
The successful candidate is expected to have a strong background in one of the following disciplines: engineering, physics, mathematics, fluid dynamics, heat and mass transfer, combustion. Any previous experience in theoretical analysis and/or numerical studies is welcome. The research will be conducted at the HySAFER Centre. The candidate will focus on CFD modelling and numerical simulations, use relevant software (ANSYS Fluent, FieldView, etc.) and the state-of-the-art computational resources – multi-processor workstations available at HySAFER Centre and Kelvin-2 High-Performance Computing facilities. This research will be aligned to relevant HySAFER’s projects, results reported at international conferences and published in peer-reviewed journals.
Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.
We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.
In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.

The Doctoral College at Ulster University
I had an interesting time at Ulster University, Jordanstown. Many thanks to all the lecturers, library staff and research school for their time and effort getting me through my PhD!
Philip Bradley - PhD in Architecture, Built Environment and Planning
My primary research interests focus on sustainable construction materials for the delivery of environmentally responsible building and infrastructure systems. Within that field, I am particularly interested in the combination of geopolymer binders and recycled aggregates as construction materials with a balance among technical, environmental and economic factors.I would like to express my appreciation to my supervisors and the technicians/staffs at School of Built Environment, for their consistent support, valuable feedback, attention to details, patience and encouragement during my PhD course.
An Huynh - PhD in Architecture, Built Environment and Planning
This journey is quite a challenge for me. I am proud of me finally getting through my PhD. And I’ll never forget the valuable memories that Ulster University has given me, the people, the beautiful sceneries, the happiness, the language improvement, and the hard work. I would like to express my sincere thank you to my supervisors, my colleagues, my friends and my family. I couldn't have got through my PhD without your help and support. I know that you will continue to pay attention to my growth path in the future and be happy with my achievements. So, I’ll take all the knowledge I have learned and keep on working for a better future.
Shurui Wang - PhD in Architecture, Built Environment and Planning
My proudest moment was when I was accepted to pursue my PhD in Ulster University. My favourite memory was how I met my group of friends who also pursue their dreams in this foreign country. I'll never forget the tough times I underwent during my study, but thanks to those times that I finally managed to lose weight. I couldn't have got through this without my supervisors' support, kind encouragement and firmest trust. If I could speak to myself at the start of my PhD, the best piece of advice I would give myself would be - do not procrastinate, you gotta learn to move forward in life when you feel stuck.
Mengmeng Dou - PhD in Architecture, Built Environment and Planning
I came to Ulster University to challenge myself with a PhD study under Vice-Chancellor's Research Studentship at the Centre for Sustainable Technologies in Architecture, Built Environment and Planning. My supervisors helped me much from giving valuable guidance to supporting any difficulties, which makes me feel that I am the luckiest student.I would like to take this opportunity to thank my supervisors, family, friends and colleagues for supporting me tirelessly. Without you, I couldn't have got through my PhD with some great achievements:Best PhD Research Paper in Architecture, Built Environment and Planning, Ulster UniversityBest Student Paper Award at the conference of World Congress on Engineering and Computer Science 2017, San Francisco, USA.Student Registration Grant for demonstrating academic excellence in research at 17th International Conference on Sustainable Technologies (SET 2018), China.
Khoa Xuan Le - PhD in Architecture, Built Environment and Planning
My academic background includes a MSc in Process Safety Technology, in which my topic of thesis involved the use of hydrogen as an energy carrier. This prompted me to further my knowledge in this field by embarking on a PhD at the HySAFER institute at Ulster University. Here, I conducted research on the consequences of stored hydrogen tank rupture in confined space, with the use of computational fluid dynamics.My proudest moment in all of this was informing my parents, not only for being accepted as a PhD researcher at Ulster University, but also after three years that it was indeed completed. It goes without saying that without the guidance and support from my supervisors, the companionship created by my fellow colleagues with whom I shared an office with, and the people otherwise encountered and befriended during this period, the light at the end of the tunnel of it all would have rather been a train. And for that, I will be forever grateful and all the attained memories preserved
Wulme Dery - PhD in Architecture, Built Environment and Planning
I worked for 35 years for the Housing Executive - latterly as its Head of Research. I had completed an MSc in Urban Policy in the 2000s - and it had been a longstanding ambition of mine to complete a PhD that brought together a number of strands of policy-related research that had been of particular interest to me. Undertaking a PhD at Ulster University allowed me to fulfil this ambition in an enjoyable manner.Completing my PhD has brought me an immense amount of personal satisfaction. A major part of this was down to the incredible support I received from my two supervisors Professor Stanley McGreal and Dr Michael McCord. Their ongoing advice, encouragement and support helped take me outside my comfort zone and played a major part in my achievement. Even my viva proved to be an enjoyable experience and enabled me to feel that I had gained a level of expertise in a sphere that could make a small but significant contribution to addressing some of the key housing issues facing policy
Joe Frey - PhD in Architecture, Built Environment and Planning
I am a senior researcher at Korea Fire Institute which is a state-owned company specialised at fire safety engineering in the Republic of Korea. I obtained BSc and MSc in mechanical engineering. Prior to enter a PhD course at the School of the Built Environment in Ulster University, I worked for over a decade in the engineering industry. With relation to my PhD topic, my current research field is on fire safety using experimental and numerical approaches.Finally, I finished my study in Ulster University and became a Doctor of Philosophy in a field of fire safety!! There were a lot of good memories at Ulster University. I will never forget the rainbow on the Jordanstown campus which helps me to relieve my stress caused by stuck in concrete damaged plasticity theory. I felt great when receiving an annual PhD conference award as the best poster. I was excited to spent time with my officemates, Rumeel, and Emmanuel. I love every moment at Room 4B01 because it was a time to enhance my

Benjamin Fumey - PhD in Architecture, Built Environment and Planning
I studied my Integrated Masters (MSci) at Jordanstown from 2008-2012. After a few years working as an Estate Agent, I went back to academia to complete my PhD, looking at the broad area of health within the field of planning.Many PhDs are given a topic to begin with, however when I applied for the PhD scholarship I had to create my own research topic. This took me a while to establish, but eventually my hard work paid off and I narrowed my research into an area I am truly proud of - Active living, how the built environment can influence physical activity and how this was interpreted in the domains listed in my thesis title. My favourite aspect of the PhD was presenting my research and getting the acknowledgment from other academics that my research was interesting, robust and well thought out. I submitted an abstract to AESOP, an annual planning conference, and was given the opportunity to present my work in Venice. I also presented my work to the president of RTPI. There is nothing
