Human factors integration is strengthening complex submarine design programmes by improving collaboration between engineering, operations, and design disciplines. Through structured governance, engagement, processes, and specialised tools, teams are improving traceability, decision-making, compliance management, and spatial design outcomes. Lessons learned provide a foundation for more effective, scalable, and defensible future programmes.

Virtual reality adoption in naval applications remains constrained by cybersickness and human-factor challenges. Testing a headset-based sensory-conflict mitigation system showed symptoms typically emerged after eight minutes, while demonstrating potential for partial relief under specific conditions. The findings inform safer immersive training, simulation, and operational use of VR technologies in defence.

E-navigation is enabling safer, more coordinated maritime operations through digital route exchange between ships and shore. The Moving Havens concept visually compares planned and actual vessel positions, supporting early deviation detection, collision-risk awareness, and automated traffic management. The approach enhances safety, efficiency, and decision-making across increasingly connected waterways worldwide today.

Human factors research must account for culture as well as technology. Examining differences between Eastern and Western perceptions of safety, the analysis shows how national culture influences decision-making, risk awareness, and human-system interaction. The findings highlight essential considerations for autonomous operations and globally effective transportation safety strategies today and beyond.

Communities of practice play a crucial role in developing ship-handling expertise. Survey results show that much of the profession’s knowledge is acquired collaboratively and through experience at sea rather than formal instruction alone. The findings underscore the value of onboard mentoring, shared learning cultures, and practical training for maritime competence.

Extensive sea trials and laboratory testing helped identify optimal shock-mitigating seating for all-weather lifeboats. Analysing more than 2,500 wave impacts across varied crews and operating conditions, researchers validated seat performance, refined designs using military-grade protocols, and demonstrated an efficient evidence-based approach to reducing injury risks in harsh seas today globally.

Maritime safety increasingly depends on understanding how technical and non-technical skills shape control-team performance. Drawing on accident analysis and lessons from shipping and aviation, researchers argue that human-factor failures cannot be reduced to operator error alone. Richer evidence, better training, and deeper insight into human-technology interactions are essential for prevention.

Mariner 4.0 combines human digital twins and Maritime 4.0 to augment seafarer capabilities in increasingly digitalised operations. Using the SA Agulhas II as a case study researchers developed personalised virtual representations supporting comfort monitoring wellbeing decision-making and safety. The concept bridges human factors and advanced technology enabling smarter maritime workforces.

Designing ships for icy waters demands specialised hull forms, structural reinforcement, materials, and classification approaches to withstand extreme loading. Examining ice behaviour, climate change impacts, and operational requirements, the analysis highlights critical differences between ice-strengthened vessels, icebreakers, and conventional ships, informing safer, more resilient, efficient, polar maritime design strategies worldwide.

Optimising ice-reinforced ship structures is becoming increasingly important as Arctic shipping routes expand. Researchers evaluated ice-belt configurations under Finnish-Swedish ice-class requirements assessing materials spacing and framing alternatives. The findings identify lighter structural solutions that maintain strength enhance efficiency and reduce vessel weight supporting safer more economical ice-going operations globally today.

Electric water taxis are being reimagined for modern cities through lightweight catamaran designs that combine solar energy, low noise, minimal wake generation, and enhanced passenger comfort. With strong emphasis on accessibility, safety, ergonomics, and operational efficiency, the concept offers a sustainable and attractive future for urban waterborne transport systems globally.

ESPOmar demonstrates how multidisciplinary vessel design can support sustainable regional maritime transport in the Gulf of Cadiz. Through optimisation, innovative propulsion, lightweight structures and passenger-centred design, researchers developed two distinct ferry concepts, one focused on low-carbon commuting, another on tourism. Together they showcase practical pathways for cleaner, more attractive mobility.
