“…Research on fin stabilizers is divided into 3 major parts, namely optimization of life force [9][10] [11], fin movement control system [12][13][14] [15], area and angle and zero speed [16] [17]. Several optimization methods have also been used in the selection of fin stabilizers such as the TOPSIS method (a Technique for Order Preference based on Similarity to the Ideal Solution), Analytic Hierarchy Process(AHP) and Entropy Weighting Method (EWM) [18], Adaptive Dynamic Programming (ADP) [19] recurrent neural network (RNN) [20]. All research is done to improve good anti-rolling ability by making the appendages resistance caused by fin stabilizer as small as possible.…”

The main function of the fin stabilizer on patrol boats is anti-rolling and providing comfort for ship personnel. However, the installation of the fin stabilizer has a consequence in the form of appendage resistance of the ship. This study analyzes the magnitude of the appendage resistance due to the installation of the NACA 0010 stabilizer fin mounted on a 60m patrol boat at an angle of 0º. Reduction of ship resistance is expected to improve the ship performance which then can optimize the use of fuels and minimize pollution. In the early stages, the bare hull was validated with the results of the model test on the towing tank with a resistance difference of less than 3%. Based on the simulation results, it is known that the average resistance value of Fine Marine Numeca is 1.87% higher than the resistance value of the Maxsurf software. From the results of testing the appendage resistance value with 3 variations of the shape of the NACA 0010 fin, it is known that the appendage resistance value of fin stabilizer 2 is 1.04%, fin stabilizer 1 is 1.26% while fin stabilizer 3 is 1.6%. The appendage resistance of fin stabilizer 2 is smaller than the variation of fin stabilizer 1 and 3 models.

“…When sailing in rough sea conditions, the ship stability is affected by roll motion, determine exact dynamics forces that affect to the vessel motions is very difficult, in this paper, we study the stability of the vessel in relative to roll motion. So, the ship nonlinear active fin model is given as [23], [24].…”

<span>Adaptive backstepping control based on disturbance observer and neural network for ship nonlinear active fin system is proposed. One disturbance observer is given to observe the disturbances of the system, by this way, the response time is shorten and the negative impact of disturbance and uncertain elements of the system is reduced. In addition, radial basic function neural network (RBFNN) is proposed to approach the unknown elements in the ship nonlinear active fin system, therefor the system can obtain good roll reduction effectiveness and overcome the uncertainties of the model, the designed controller can maintain the ship roll angle at desired value. Finally, the simulation results are given for a supply vessel to verify the successfulness of the proposed controller.</span>
