How long is the engineering log retained onboard the ship?

The duration for which the engineering log is retained onboard a ship is three years. This retention period is critical for ensuring that there is a comprehensive history of engineering operations, maintenance, and any incidents that may have occurred during that time. Having a three-year log allows for effective tracking of equipment performance, compliance with regulatory requirements, and facilitates audits and investigations if required.

The engineering log serves multiple purposes, including documenting routine checks, repairs, modifications, and the overall state of the ship's systems. By retaining these logs for three years, the ship's crew can reference past data to identify trends, address recurring issues, and maintain operational efficiency. This period strikes a balance between sufficient historical data availability and the management of storage resources onboard, making it a standard practice within naval operations.
