Napa of Finland has been working with industry leaders as part of the EC FLARE project with the aim of increasing passenger ship safety, with Napa experts leading the Flooding Accident Response team.

The work involved developing a risk-based methodology to enable 'live' flooding risk assessment and control for passenger vessels. The Napa Emergency Computer and Napa Fleet Intelligence have been used to assess the vulnerability of an intact ship as well as its survivability in case of a flooding emergency. Aalto University and Napa studied existing operational data from passenger ships which had previously experienced varied and volatile weather conditions, which enabled an assessment of the conditions’ accident potential and estimation of the risk of a flooding accident occurring.

Napa Fleet Intelligence found that traffic density and bathymetry are key factors when assessing the risk of a vessel collision or grounding. The severity of these two factors are directly related to an increase or decrease in the risk of flooding onboard a vessel. Combining the ship position data received from AIS, with sea weather conditions and bottom bathymetry, enabled further depiction of real operating conditions.

Through systematic study of such large volumes of data, statistical information could be provided on the risk that marine traffic and weather conditions pose on the flooding of passenger ships. For example, by combining the traffic with the weather encountered, it was found that wave conditions are in fact less severe for passenger vessels than general statistics have previously suggested.

With the FLARE project due to run until the end of 2022, Napa expects its research to have a significant influence in improving passenger ship safety.
