What is the duration for which bell logs are maintained?

Bell logs are crucial for documenting the operational data and performance metrics of gas turbine systems. The standard duration for maintaining bell logs is three years. This time frame allows for comprehensive review and analysis of performance trends over a significant operational period, facilitating effective maintenance planning and troubleshooting. Keeping the logs for three years ensures that records of operational anomalies or trends are available for engineers and technicians tasked with maintaining the equipment, helping them identify patterns that could indicate underlying mechanical issues or performance drops. This duration aligns with industry practices and regulatory requirements, thus reinforcing the effective management and operational safety of gas turbine systems.
