漂浮式海上风电机组全生命周期成本分析

针对国内漂浮式风电全生命周期成本研究尚不足的问题，提出一种评估漂浮式海上风电机组全生命周期成本细分的方法。该方法将漂浮式海上风电机组全生命周期划分为前期调研、设计、制造、安装、运行维护和拆解等6个阶段，涉及每个阶段的阶段成本，并将各阶段成本细分为不同的子成本，得到全生命周期多层次成本构成，并据此分析获得影响全生命周期总成本的关键变量。以某半潜式浮式风机为例，分析其全生命周期每个阶段的成本构成，从而获得最重要的成本，并将其最小化以提高浮式风机经济效应。研究结果表明，控制制造成本和安装成本是提高浮式风机经济性的关键。

Whole Life Cycle Cost Analysis of Floating Offshore Wind Turbines

Aimed at the problem that the study of the whole life cycle cost of the floating offshore wind turbine is insufficient in China, a method is proposed to evaluate the whole life cycle cost segmentation of the floating offshore wind turbines. The whole life cycle is divided into 6 stages, which are pre-investigation stage, design stage, manufacturing stage, installation stage, operation and maintenance stage and dismantling stage. The cost of each stage is subdivided into different sub-costs and the multi-level cost composition of the whole life cycle is obtained to obtain the key variables that affect the whole life cycle cost. Taken a semi-submersible floating turbine as an example, the cost composition of each stage of the whole life cycle is analyzed to obtain the most important cost, and it is minimized to improve the economics of the floating offshore wind turbine. The research shows that controlling the manufacturing cost and installation cost is the key to reduce the whole life cycle cost of the floating offshore wind turbine.
