C At least three PRS with Median Test enabled.
D At least one gyro and one PRS enabled.

Question

Accepted Answer

To accurately set up a Dynamic Positioning (DP) vessel in the Auto Position Mode, it's essential to understand the role of sensors and how they contribute to the system's functionality. DP systems rely on a combination of sensor inputs to maintain a vessel's position and heading by automatically controlling its propulsive and thruster forces.

Here's a breakdown of the options you've provided:

A. At least two gyros with no errors enabled.
- Gyrocompasses provide heading information, which is crucial for DP operations. However, solely relying on gyros would not suffice for auto position mode as they do not provide position or motion reference.

B. At least two gyros and three PRS enabled.
- This option includes both gyrocompasses for heading information and Position Reference Systems (PRS) for position information. The redundancy in both systems enhances reliability, making this a viable setup for auto position mode.

C. At least three PRS with Median Test enabled.
- Having multiple PRS with a median test can ensure reliable position information by eliminating outlier data. However, without gyro information, the system lacks heading data, which is also critical for maintaining the vessel's orientation.

D. At least one gyro and one PRS enabled.
- While this setup provides both heading and position information, the lack of redundancy makes it less reliable than setups with multiple sensors, especially for operations requiring high precision and safety.

Based on these considerations, the most appropriate answer for setting up a DP Vessel in the Auto Position Mode would be:

**B. At least two gyros and three PRS enabled.**

This option provides both redundancy and a combination of critical sensor inputs (heading and position) necessary for effective and reliable auto position control.
