In this report we have investigated and analyzed drowning accidents, specifically in harbours. The empirical knowledge that was used for this report is accounted for in the form of collection and categorization of larger datasets from Rådet for Større Bade- og Vandsikkerhed. An Expert Interview with Erik Bech, chairman of the council, will also be accounted for in this report. With these components we have described the harbor as a complex technological system and analyzed it through an Actor-Network-Theory Analysis and Complex Systems Analysis. This succeeded in gaining a greater understandin

This report attempts to solve the issue of the vulnerability in Port Safety´s product, LifeLadder. It does so, by designing an artefact which adds flexibility to a specific part of the modular system of LifeLadder, that part being the spacer. The report documents the process of analysing the problem, designing the solution, and testing the solution. The analysis is done using the theory of TRIN. With an adequate understanding of the problem, the design process can begin. This project is done based on the methods of iterative design and rapid prototyping.
