DP - Thrust Capability Curve
Available thrust envelope for DP station-keeping given number of thrusters and worst-case single-failure scenario.
Total thrust
2,400kN
Post-failure thrust
1,600kN
Post-failure / intact
0.67 -
Formula, assumptions, and limits
IMCA M140 requires post-failure thrust ≥ environmental demand. Split thrusters into independent groups to avoid common-cause failure. Azimuth thrusters 360° vs tunnel 180°.
