What type of motor data is required in the system installation documentation?

The appropriate motor data required in the system installation documentation is propulsion motor data. This information is essential as it directly pertains to the main driving force of the vessel, which is vital for its operation and performance. Propulsion motor data typically includes specifications like the motor type, power rating, efficiency, operating voltage, and any specific installation requirements.

This data is necessary to ensure proper integration with the vessel's electrical system and to comply with safety and performance standards. Understanding the propulsion system's requirements helps in troubleshooting and maintenance and ensures that the motor operates within its designated parameters for optimal performance.

In contrast, while auxiliary motor data, cooling system data, and navigation system data are certainly relevant in the broader context of marine systems, they do not hold the same critical importance as propulsion motor data when it comes to the overall installation and operation of a vessel.
