John Carlton

Professor John Carlton is a Professor of Marine Engineering at City, University of London, where he leads postgraduate maritime studies. He is also affiliated with the International Institute for Cavitation Research. Prior to his academic role, he held senior positions at Lloyd's Register, including Global Head of Marine Technology and Head of the Technical Investigation Department.

• BA (Hons) Mathematics, Open University, 1976
• Professional qualifications in Mechanical Engineering (IMechE, 1969) and Marine Engineering (CMarEng, 1990)
• Honorary Doctor of Science (DSc), City, University of London, 2006

His research focuses on ship propulsion hydrodynamics, cavitation dynamics, and future ship powering systems. He has made significant contributions to understanding marine propeller behavior, propeller-rudder interaction, and machinery condition monitoring. His work integrates theoretical, computational, and full-scale experimental methods.

The recent publications highlight a strong trend toward advanced sensing technologies (e.g., fibre optic sensors) for monitoring cavitation, structural integrity, and machinery health. His research spans hydrodynamics, acoustics, materials science, and sustainable propulsion, reflecting a multidisciplinary approach to marine engineering challenges.

• Denny Gold Medal (IMarEST), twice awarded
• Stanley Gray Award for Marine Technology, twice awarded
• Honorary Doctor of Science, City, University of London (2006)
• Fellow of the Royal Academy of Engineering (2011)
• 109th President of IMarEST (2011–2012)

Professor Carlton has supervised numerous industry research projects and contributed to international standards. He is actively involved in advising on alternative propulsion systems and has led research initiatives in nuclear propulsion feasibility and risk assessment for merchant ships. He chairs the Royal Academy of Engineering’s Working Group on Alternative Ship Propulsion.

He is a key member of the International Institute for Cavitation Research and collaborates with industry partners on structural health monitoring, cavitation erosion, and propulsion efficiency. His work bridges academic research and practical marine engineering applications.
