Following the latest published Safety Flashes from IMCA, it is described a near miss incident due to damaged rig hose.
The incident
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.
Findings
Rig side hose inner lining parted from sheath and got caught between connections.
Lessons learned
- Ensure that hoses are in good condition, properly certified, and in compliance with required standards, before use;
- Conduct a visual check on hoses before use;
- Remember that anyone can enact stop work authority if they see something unsafe.
