An offshore anemometer tower was constructed to obtain the data of wind energy resources near the vi-cinity of Nanri Island. During its foundation design, construction and installation, the foundation stress, design pa-rameters and load combinations in the special sea environment were analyzed and calculated. A variety of tech-nologies such as basic construction techniques, antiseptic treatment were adopted. The integral hoisting technology was used in tower installed, and boot devices were designed to ensure the tower to be put exactly in place. The projects would provide references for similar offshore works of offshore wind farms.% 为获得南日岛海域的风能资源数据，在该海域设计建造了一座自立型测风塔。在测风塔的基础设计、施工过程中，分析计算了海上特殊施工环境中的基础受力、设计参数及荷载组合，因地制宜地采用多种基础施工工艺、防腐处理等技术；在塔体安装时采用了整体吊装技术，并设计了引导装置保证了塔体准确就位。该工程可为海上风电场开发及类似海上工程提供参考。
