Abstract [en]

There is a lack of standardized methods for socio-economic evaluations within the maritime transport sector. This paper presents a model for analysing and quantifying the intensity and severity of ship conflicts using AIS (Automatic Identification System) data and expert assessments. Also, a case study applying the proposed method to the Southern Gothenburg Archipelago is carried out. The goal is to contribute to cost-benefit analyses within the maritime transport sector by a better understanding of how different actions, such as the widening of fairways or new regulation, impact maritime safety. The importance of validating the model by comparing its results with independent sources of reported maritime accidents is emphasized, and the challenges of using existing accident statistics for this purpose is discussed. The basic model described in the paper can be built upon by differentiating parameters by region and vessel type, account for seasonality etc. Furthermore, a downstream consequence analysis model is needed to enable a monetary valuation of (the consequences of) identified conflicts. Finally, the same principles as laid out here for conflict analysis can also be adopted to the identification of groundings.
