The mastery of human factors can improve the safety of high-speed workboats

Increasingly fast workboats are used in areas such as rescue, defense, and law enforcement, as well as in the maintenance of maritime infrastructure. Higher vessel speeds and more complex operating environments have increased the cognitive load on crews and the demands of decision-making.

According to the research in public management by Mikko Lehtimäki (MSc), incident and accident analyses still focus too heavily on errors made by individuals. This often leads to overlooking other factors that influence safety, such as crew cooperation, resource management, technology, and operating procedures.

– Safety cannot be developed by looking only at the actions of a single individual. We need an understanding of how people, technology, and the organisation work together, Lehtimäki states.

Analysis of accidents and incidents

The doctoral study modeled the competencies and behavioral markers of high-speed workboat crews and analysed the management of mental workload. The research data consists partly of analyses of accidents and incidents, as well as field research. The framework utilised includes the Finnish HF Tool concept and international civil aviation training standards.

– The results of the study can be applied to the development of high-speed workboat and vessel operations, as well as to cooperation across safety-critical sectors, says Lehtimäki.

The findings highlight the importance of technology usability, cockpit solutions, and standardised operating procedures. Additionally, the research emphasises the need for a proactive safety culture and decision-making based on research data.
