HUMAN FACTORS IN SHIP DESIGN AND OPERATION: A PRELIMINARY SURVEY OF THE THEORETICAL CONSTRUCT

This technical note presents an analysis of the underlying factors of human factors in ship design based on questionnaires distributed on two offshore supply vessels operating in the Norwegian Sea. The concept of human factors in ship design is still evolving. The purpose of this paper is to present a preliminary model of the human factors construct by using a factor analysis method. The results confirm the existence of controllability, workability and habitability as the principal factors of human factors in ship design. Three other factors that emerged are cargo facilities, reliability, automation and maintainability (RAM) and interfacing complexity. Bridging variables found between these factors include elements such as safety, manoeuvring, engine room and bridge design. A preliminary model of how the components or parts relate to human factors in ship design and operation is developed. The model also indicates the parties who are responsible for the various aspects of ship design from a human factors perspective.
