Multi-objective design optimization of marine gyrostabilizer for improved anti-rolling and power recovery performance

This paper focuses on the influence of the gyrostabilizer system’s parameters on its anti-rolling performance and power recovery efficiency. Firstly, the model of ship-gyrostabilizer is constructed from Conolly theory and the gyrostabilizer’s operational principle. Then, single-factor and orthogonal simulations are carried out for the gyrostabilizer parameters’ sensitivity analysis and optimization. Compared with the benchmark case, the optimized parameters provide better performance in ship stabilization and power recovery. This research provides guidance for the parameter design of gyrostabilizers to enhance anti-rolling and power recovery performance.
