@amazeifystore: The bow door didn’t have to break to defeat watertight design. 🚢 With the Herald of Free Enterprise leaving Zeebrugge and the bow doors open, seawater flooded the vehicle deck and spread sideways through the free-surface effect. The lesson is bigger than one door: safety depends on closure, confirmation, and procedure working together. Would you redesign the door, the system, or both? Save this as a reminder that the door was never the whole system. #MaritimeSafety #SafetyEngineering #SystemsThinking #HumanFactors #EngineeringLessons #RiskManagement #ShipSafety #FreeSurfaceEffect #SafetyCulture #EngineeringTok
