摘　　要：[目的]作为重要的舰用动力装备,舰用燃气轮机的研制具有难度大、周期长、费用高的特点,其经济性是十分重要的评价指标。因此,有必要在立项阶段通过主要指标和参数对其主要寿命周期费用进行估算,开展寿命周期的经济性评估。[方法]首先,收集整理典型舰用燃气轮机的技术指标、物理参数、费用等数据,建立研制费、订购价格的参数法估算模型,并进行验证。同时,结合运行、维护维修等阶段费用发生特点,建立主要寿命周期费用分析框架与估算模型。[结果]结果显示,建立的研制费、订购价格模型估算误差在5%以内;建立的运行费、维护维修费估算方法贴合实际,易于使用。[结论]研究表明,建立的寿命周期费用分析框架与估算模型具有适用性与可行性,可为舰用燃气轮机立项阶段的经济性分析工作提供有效支撑。[Objectives]The marine gas turbine is an important piece of marine power equipment, and its development is characterized by great difficulty, long cycle and high cost. Thus, the cost-effectiveness is a significant evaluation indicator. As such, it is significant to estimate the major life cycle cost of marine gas turbines based on their dominant technical indicators and parameters, as well as to further evaluate their full life-cycle economy during the early proposal stage.[Methods]The technical indicators, physical parameters and cost data of typical marine power equipment are collected to build a development cost model and purchase price estimation model which are validated against existing data. At the same time, combined with the cost characteristics of the operation and maintenance stages, a main life cycle cost analysis framework and estimation model are established.[Results]The development cost and purchase price models achieve high accuracy with an error less than 5%, while the estimation method for operation and maintenance is plausible and easy to apply to real work.[Conclusions]Validation against the available data shows that these analytical framework and estimation models are applicable and feasible. This paper proposes effective approaches to support economic analysis in the marine gas turbine proposal stage.
