Summary
A tanker cargo discharge stopped when a duty AB activated emergency shutdown after observing a minor leak, without coordinating with the cargo control room. Copper tubing had failed through vibration fatigue. The flash describes revised shutdown procedures, coordination training and periodic vibration risk assessments, with tubing dampers or supports under consideration.
