What happened?
A vessel was engaged in routine operations receiving contaminated oil-based mud from a rig. Upon disconnecting the rig hose and vessel side coupling it was discovered that the inner rubber lining of the rig hose had peeled out and got caught at the junction of the connection.
It was determined that should the blockage have prevented the flow of oil-based mud it could have resulted in a significant environmental incident as a result of hose failure due to back pressure.
