In the past decades, there have been many fires on ro-ro ships and a major challenge is smoke and fire spread. RoBound was a research project which aims to clarify how "state-of-the-art" in passive fire protection between ro-ro spaces and adjacent spaces affects fire and smoke spread, and on this basis make recommendations on appropriate improvements. This was achieved through fire experiments, simulations, literature study of incident reports and regulations, and a workshop for identification of weaknesses and in collaboration with vessel operators, industry and authorities. This report documents the literature study of the project, covering a review of relevant regulations and lessons learned from previous incidents. The report also document the workshop.
