On considering the safety of the small fishing vessels in the rough sea, it is important to estimate accurately the structure of the dynamic rolling response of the small fishing vessls, since the seakeeping qualities are generally worse than those of big ships and strong nonlinear responses frequently exhibit on the rolling motions. There are difficulties to forecast appropriately the rolling motion by using the differential equation, which is based on the physical model, because of large changing the ship condition during the fishing operation. From this point of view, the authors took notice of a methodology for applying a Neural Network model carried out. As the result, the effectiveness was suggested on the forecasting by the Neural Network model to the structure of the rolling response of small fishing vessels.

Two computer simulations which express the fuel consumption q [kg/h] of small squid jigging boats when fishing lights are in operation, as a function of the rated output of main engine RP [kW] , the rated power of the generator RL [kW] , and the electric power consumption L [kW] of the fishing lights, Were developed. q=fn(RP, RL, L) One is for the proposed generator, a standard brushless generator for fishing boats and merchant vessels, and the other is for a conventional generator for small squid jigging boats.The estimated fuel consumption by the former simulation and by the later simulation was compared, and the effect of reducing fuel consumption by the standard brushless generator was evaluated. The results of computer simulation show that the savings are estimated to be l.8% of the fuel consumption per year, or approximately 58,000 yen per year.
