近海石油平台支援船主机油耗优化模型的建立

针对近海石油平台支援船进行研究,建立了近海石油平台支援船关于风、浪、潮汐的船舶数学运动模型并计算了目标船裸船体阻力和附体阻力；根据主机功率的传递过程以及船舶有效功率的估算方法,建立船舶主机油耗优化模型；之后运用基于遗传算法的多目标优化方法对主机油耗优化模型进行计算与验证,结果表明优化后的主机油耗模型具有良好的节能效果。

Study and Establishment of Offshore Support Vessel Main Engine Fuel Consumption Optimization Model

The OSV is studied in this paper. Firstly, establishing the wind, wave and tide shipping mathematical motion model and calculating the exposed resistance of the ship; Then, establishing the main engine fuel consumption optimization model as the optimized model according to the transmission process of the main engine and the method of calculating the effective power of the ship; Next, optimizing the optimized model by using the multi-objective optimization method based on the Genetic Algorithm to get the optimization results. And the results show that the optimized engine fuel consumption model has good energy saving effect.
