RoRo Passenger Vessel Technical Audit
Independent technical audit of RoRo passenger vessels covering structural condition, RoRo cargo spaces, watertight integrity, machinery, fire safety, life-saving appliances, navigation, emergency systems and operational readiness.
RoRo Passenger Vessel Technical Audit
RoRo passenger vessels combine passenger accommodation, vehicle and cargo spaces, complex access arrangements and critical watertight and fire safety systems. Their technical condition therefore requires a vessel-specific assessment covering both conventional ship systems and the particular risks associated with RoRo operations.
PAMS Pacific Admiralty Maritime Services provides independent technical audits for RoRo passenger vessels, focusing on the condition, functionality, documentation and operational readiness of systems relevant to the vessel's statutory and trading requirements.
The audit can be tailored to passenger ferries, vehicle/passenger ferries and other RoRo passenger vessels according to vessel design, flag, class, route, passenger capacity, vehicle capacity and applicable statutory requirements.
Why RoRo Passenger Vessels Require a Dedicated Technical Audit
RoRo passenger ships have particular safety characteristics arising from their large vehicle decks, cargo access openings, passenger accommodation and the consequences that flooding, fire or cargo movement may have on vessel safety. IMO identifies RoRo passenger ships as a specific area of passenger ship safety and has developed dedicated requirements following major RoRo casualties. :contentReference[oaicite:1]{index=1}
