dc.description.abstractDuring the last decade the shipping industry has been subjected to regulation amendments that resulted in a need to reduce ship emissions to air. Nitrogen oxides and sulphur oxides belong to the pollutants that were targeted for reduction. As a consequence, there has been an increased interest in technologies that reduce the amount of pollutants emitted by ships. The number of installed abatement units is growing, as they are installed new failure modes are introduced among the systems onboard ships. In order to understand the potential hazards involved in installing and operating the technologies, a study of existing solutions was carried out highlighting several potential failure modes with every technology studied. Since no dedicated rules exits for abatement technologies, and to be able to limit the possible causes and effects of failures associated with the technologies, the failure modes were compared to the current rulebook of the classification society Det Norske Veritas. The aim was to find suitable existing regulations applicable to the studied technologies. The rules were spread through various chapters of the rulebook without focus towards abatement technology. The results of the technology study revealed various failure modes, among the most common belonged corrosion, increased backpressure and insufficient measures to ensure fail to safe principles. The comparison between potential failure modes and current rules revealed a gap containing unregulated potential hazards. This background study resulted in a compilation regarding unregulated hazards. It will serve as a basis for rulemaking towards safe installation and operation of abatement technologies.
