Wpływ podziału grodziowego na bezpieczeństwo statków typu RO-PAX
i ich bezpieczny powrót do portu
Subdivision of Ro-Pax Ships for Enhanced Safety in the Damage Conditio
and Safe Return to Port
It is the priority of Polski Rejestr Statków to ensure the safety of people and cargo at sea. PRS Rules are based on international conventions and regulations as well as on in-house R&D projects.
PRS Rules relating to the safety of ro-ro passenger ferries include, among others:
Both publications present requirements for passenger ships that warrant subdivision for rescue and salvage operations and possible safe voyage to port in the case of damage (flooding or fire).
Specialised software was developed under one of PRS R&D projects to calculate stability in intact and damaged condition and to generate numerical simulations of ship behaviour in waves. Comparative computations were carried out for various bulkhead compartment configurations indicating the safest solutions.
When traditional methods of increasing the subdivision index is not possible new structural solutions are proposed such as minimum height double bottom, double skin or double vehicle deck.
