Since before the entry into force of SOLAS2009, on 1st January 2009, amendments were found to be necessary. Hence, over the past decade or so the various elements of Damage Stability Regulations and Explanatory Notes relating to Passenger ships and specifically the safety and survivability of RO-PAX ships have been enhanced. These significant developments, relating to the Required Subdivision Index, R, and the Probability of Survival Factor, s, which contributes to the Attained Subdivision Index, A, have been incorporated into SOLAS2020, which entered into force on 1st January 2020. However, at present RO-PAX ships operating in European Union waters must still also comply with the existing Stockholm Agreement.
In the May 2020 issue of The Naval Architect magazine, published by the Royal Institution of Naval Architects (RINA), Safinah Group’s Keith Hutchinson and Andrew Scott of the Maritime and Coastguard Agency discuss the new SOLAS2020 Damage Stability Regulations for RO-PAX ships, together with possible future developments.
