Operation and Control of Hybrid Anti-Rolling System on Ships

摘要

The hybrid anti-rolling system is automatically controlled to maintain the safety and reliability of both the ship and the system, using the following conditions. When the ship rolling is below the design condition, the mass displacement is controlled so that the designed effect of the system can be obtained. When the ship rolling is extreme, the mass movement is controlled not to reach the stroke end even if the system would overshoot the ordered point. When the ship rolling is small, the system stops automatically (auto-sleep). The control method of the hybrid anti-rolling system is described with reference to the first system applied to the oceanographic research vessel "MIRAI", and operated continuously for almost one year without any problem.
