DP Station-Keeping - Footprint Radius
DP station-keeping footprint radius under a given environmental load, based on worst-case single-failure capability - the practical output of IMCA M140 analysis.
Thrust utilisation
0.72 -
Indicative footprint
6.5m
DP status
Green - within capability
Formula, assumptions, and limits
Very simplified screening - full IMCA M140 capability plot requires wind/wave/current envelope with post-failure thrust. DP class 2/3 requires post-WCF utilisation < 1.0.
