Dynamic positioning (DP) capability analysis plays a very important part in DP system design. Mathematically, it is a typical nonlinear constraint optimization problem. Simulated annealing algorithm (SAA) is an effective way in solving this kind of problems. In this paper, SAA is utilized in DP capability analysis. And two vessels’ capability is evaluated as example. The results meet well with Kongsberg’s re-port, and show that DP capability analysis based on SAA is reliable and successful.
