【摘要】：在能源日益枯竭、环境日益恶劣的当今,“节能减排”已经成为社会发展的主流,船舶能效设计指数(EEDI)的强制性实施更是对整个船舶设计建造行业提出更高的要求。主机为船舶动力装置的核心,其能耗占整个船舶的80%以上,因而主机性能的好坏,将直接影响整艘船舶的能效水平。本文以船舶能效设计指数(EEDI)为背景,以上海船舶设计研究院设计的三种绿色船型Dolphin38.8K、64K和82K为研究对象,重点研究分析以柴油机为主动力装置的船舶主机选型过程中,动力装置相关参数的设定对EEDI所产生的影响,并将EEDI作为衡量主机选型优劣的指标之一,建立船舶主机选型综合评价模型,以实现对船舶主机选型进行科学、客观、合理的评价。首先,系统地研究船舶能效及主动力装置选型基本理论,分析EEDI和EEOI的计算方法及其对船舶行业所产生的影响和本身存在的不足,以某82000DWT型散货船为例,介绍主机选型主要过程和计算方法。其次,分析船舶能效设计指数的主要影响因素,从EEDI公式角度出发,分析船舶主要设计参数对EEDI产生的影响,并重点研究了船舶主机选型过程中相关技术、参数的选取对EEDI所产生的影响,定性的给出提升船舶能效水平的措施、方法。再次,引入EEDI作为评价船舶主机选型的指标之一,建立船舶主机选型模糊综合评价模型,确定评价指标及各指标权重,并以某82000DWT散货船的主机选型为例,阐述模型的计算过程,并验证其正确性。最后,利用净现值(NPV)法对船舶主机选型进行经济性研究,对各备选机型全寿命周期内的可计算成本折现分析,并以某型号主机为标准进行投资差额现值比较及投资差额回收年限对比,以判断可以提高船舶能效水平的主机,其经济性的优劣。
[Abstract]:Nowadays, energy conservation and emission reduction have become the mainstream of social development. The mandatory implementation of the Energy efficiency Design Index (EEDI) is more demanding for the whole ship design and construction industry. The main engine is the core of the ship power plant, and its energy consumption accounts for more than 80% of the whole ship. Therefore, the performance of the main engine will directly affect the energy efficiency level of the whole ship. Three green ship forms, Dolphin 38.8KN 64K and 82K, were designed by Shanghai Institute of ship Design and Research. Emphasis is placed on the analysis of the influence of the setting of the relevant parameters of the power plant on the EEDI during the selection process of the marine main engine with the diesel engine as the main power plant. Taking EEDI as one of the indexes to evaluate the selection of the main engine, a comprehensive evaluation model of the selection of the main engine of the ship is established to realize the scientific, objective and reasonable evaluation of the selection of the main engine of the ship. First of all, the basic theory of ship energy efficiency and main power plant selection is systematically studied, and the calculation methods of EEDI and EEOI are analyzed, as well as the impact on the ship industry and its own shortcomings. Taking a 82000 DWT bulk carrier as an example, the main process and calculation method of main engine selection are introduced. Secondly, the main influencing factors of ship energy efficiency design index are analyzed. From the point of view of EEDI formula, the influence of ship main design parameters on EEDI is analyzed. The related technology and the influence of the selection of parameters on EEDI are studied in detail. The measures and methods of improving ship energy efficiency are given qualitatively. Thirdly, EEDI is introduced as one of the indexes to evaluate the selection of ship mainframe, and the fuzzy comprehensive evaluation model is established to determine the evaluation index and the weight of each index. Taking the main engine selection of a 82000DWT bulk carrier as an example, the calculation process of the model is described and its correctness is verified. At last, using NPV (net present value) method, the economic analysis of the main engine selection is carried out, and the discounted cost in the whole life cycle of each alternative model is analyzed. The present value of the difference of investment and the period of recovery of the difference of investment are compared according to a certain type of mainframe, so as to judge the economy of the main engine which can improve the level of energy efficiency of the ship.
