Alternative Evacuation Procedures and Smart Devices’ Impact Assessment for Large Passenger Vessels under Severe Weather Conditions

Sci
Within the expansive domain of maritime safety, optimizing evacuation procedures stands as a critical endeavour. After all, evacuation is literally the last and fundamental safety level afforded to mariners and passengers. Recent incidents have rekindled
