In modern DP systems, what is typically required to enter Trainer mode?

To engage Trainer mode in modern Dynamic Positioning (DP) systems, it is typically necessary for the DP system to be in Stand By Mode. This is because Trainer mode is designed to simulate operational scenarios without interfering with actual vessel operation. By placing the system in Stand By Mode, it allows the instructor to safely control the training environment, ensuring that the actual DP operations can be paused, while still allowing for the learning experience to take place. This setting enables the use of simulated conditions and challenges, allowing trainees to practice their skills without affecting real-time performance. Thus, ensuring the system is set to Stand By is a critical prerequisite for accessing Trainer mode in DP systems.
