Thruster Biasing intentionally applies a small, constant thrust on one or more thrusters even when the required DP force is low.
It is a deliberate control strategy, not an inefficiency.

• When an azimuth thruster cannot deliver true zero thrust (minimum thrust required).
• When a higher power consumption is required than what is strictly needed for positioning.
• When the weather is calm and DP corrections are small.
• When heave reduction is required combined with variable azimuth mode (vessel dependent).

• Can reduce unnecessary azimuth turning when force setpoints change, improving effective thruster response.
• Can improve damping of vessel motion.
• Can improve positioning accuracy — especially at low speed.

• Turn Factor influences how aggressively an azimuth thruster rotates when force demand changes.
• Angle Factor influences how sensitive the azimuth angle is to changes in force demand.
• Takeaway: Biasing configuration is vessel-specific. Poorly tuned settings can reduce DP performance.
