Simulation of Fast Trimaran Seakeeping Amelioration Using T-foil


Fast trimaran holds excellent performance because of its high transverse stability, large deck, economy of fuel consumption and high speed. However, the highspeed craft can easily make “dolphin movement” in heading seas. The T-foil is the most effective stabilizer for alleviating the pitch and heave motions of fast craft. This work designs an autonomous trimaran motion control system utilizing a T-foil which can control the longitudinal motion of fast trimaran. Numerical simulation results show that the motion control system can satisfactorily improve seakeeping performance of fast trimaran.
