Study Notes
Sudden Disconnection of Pressurized Hose
- Contractor performing maintenance on bulk cargo methanol system
- Residual water being pumped from cofferdam
- Pressurized hose suddenly disconnected
- System pressure approximately 5.9-6 bar
- No injuries or property damage
- No one in line of fire, no contact made
What Went Wrong?
