Summary
A near miss during receipt of contaminated oil-based mud from a rig revealed detached hose lining trapped between connections. The flash identifies potential back-pressure hose failure and environmental consequences if flow were blocked, and calls for hose condition and certification checks, visual inspection before use and stop-work intervention.

Summary
After a routine transfer of mud from rig to vessel, the inner rubber lining of the rig hose was discovered to have peeled out and got caught at the junction of the connection with the vessel side coupling
