What is the purpose of the Operational Log?

The purpose of the Operational Log is to record individual equipment performance. This log serves as an essential tool for maintaining oversight on how specific systems and machinery are functioning during operations. By documenting performance, it allows for the identification of trends, potential issues, and areas that may require maintenance or further examination. This information is vital for ensuring that equipment is operating effectively and safely, facilitating timely interventions when performance deviates from expected norms.

In contrast, while documenting major repairs and tracking ship movements are important activities within a naval operation, they fall under different logs or records. Personnel shift logs are related more to managing human resources on board and do not pertain directly to equipment performance. Thus, Option B accurately reflects the primary purpose of the Operational Log, focusing on the operational status and performance metrics of equipment.
