International Journal of Industrial AbstractThe context for this study is the maritime domain and the design of shipboard workspaces. Due to the globalized nature of shipping, the traditional approach to a participative ergonomics process can be a logistical challenge since stakeholders like designers, manufacturers and operators are often scattered both geographically and organizationally. The participative design study presented in this paper addresses this challenge by exploring the ability of three types of simple three-dimensional (3D) models to act as mediating objects for representative users in order to elicit design feedback in a use scenario-workshop format. The study found that all three types of 3D models, when coupled with a scenario description, elicited several types of useful design feedback that served not only as direct input to changing proposed design parameters, but also as an unprompted long-term learning opportunity for the design team to gain insight into the lives and challenges of their users, who both work and live on board. Relevance to industryThe paper presents a procedure for a participatory design process in the maritime domain where the involved stakeholders are geographically and organizationally dispersed. Mock-up models coupled with use scenario descriptions elicited useful design feedback and an unprompted longterm learning opportunity for the design team.

Piracy can lead to risks so high that they, according to the International Maritime Organization, are tolerable only if risk reduction is not practicable or is disproportionate to the benefits achieved. Therefore, there is a need for reducing ship security risks in relation to antagonistic threats such as piracy.The aim of this study is to identify challenges for ship operators when developing their ship security management. Furthermore, this study also investigates two central aspects in the analysis; understanding the threat and understanding how a security threat affects the crew and operation of the ship.It is clear from the analysis that the importance of subjective aspects beyond a ship operators' direct control is high. This seems to be the fact for all aspects of the risk management process. The situation is also dynamic as the security risk, as well as the risk perception, can change dramatically even though there are no actual operational changes. As a result, the ship security management process is highly iterative and depends on situations on board as well as conditions out of the ship operator's control.In order to make ship security manageable the risk management has to put particular focus on methodological understanding, relevant system understanding and well defined risk acceptance criteria as well as on including all levels of the organization in the risk reduction implementation and on a continuous monitoring.
