ESREL (European Safety and Reliability) is an annual conference series ran under the auspices of the European Safety and Reliability Association (ESRA). The conference dates to 1989, but it was not referred to as ESREL until 1992. The conference has become well established in the international community, attracting a good mix of academics and industry participants that present and discuss subjects of interest and application across various industries.

This year the theme of the conference is "The Future of Safety in a Re-Connected World". The conference covers several topics within safety, risk and reliability analysis methods, maintenance, optimisation, and risk management. Special focus has been placed on how technology developments and nature induced hazards impact societal safety in a world increasingly reconnected post Covid-19 pandemic. The conference addresses methodological solutions in prognostics and health management, mathematical methods, accelerated life testing, maintenance modelling, accident and incident modelling and reliability modelling. As with previous years, risk perception and communication also play a key role. The conference application areas range from aviation systems, oil and gas, nuclear energy, autonomous systems, Natech, security, transportation, health and medicine to safety and reliability of systems that will potentially enable the transition to net-zero emissions, for example hydrogen power generation systems.

The ESREL conference returns to the United Kingdom after the 2016 event held in Glasgow. This time the conference is held in the city of Southampton. The city of Southampton, a city at the centre of global connectivity, and which boasts a rich maritime history. Both the Mayflower and, centuries later, the Titanic, left Southampton dock towards very different fates, with the former signifying the irrepressible spirit of hope and the latter signifying hubris and disaster. These voyages offer lessons on the interplay of human and technological factors, both in optimising safety and reliability and in determining what risks should considered in the first place. As such, the city of Southampton is a great location to host the ESREL conference, one of the most prominent conferences in safety and reliability.

This year, the ESREL conference includes 443 papers, 87 extended abstracts and 68 abstracts. The conference has received 739 abstracts. After a robust review process by the Technical Programme Committee, 443 papers have been accepted and are included in these proceedings. The work of peers, reviewers and Technical Panel Committee in helping the authors to improve their papers is greatly appreciated. Special thanks to the organisers of Special Sessions of the conference, for their initiative and planning which has resulted in a broad spectrum of submissions and several interesting papers.

This book is the conference proceedings. The conference attendees can access all abstracts of the submissions accepted for presentation at ESREL 2023 Southampton.

The host of the ESREL2023 Conference is the University of Southampton, and its associated Centre of Risk Research. The conference is sponsored by the University, GrifTotalEnergies and VWay. Their support is greatly appreciated.

Finally, we would like to acknowledge the organising committee, and in particular the events team in the Faculty of Social Sciences in the University of Southampton for their careful planning of the conference events, registrations, and webpage. Thanks also to our PhD students Kaiqi Xu, Hanqin Zhang and Yujia Chang for their administrative help during the paper reviewing process.
