摘要
海上塔架式单点处于海水、海泥以及海洋大气复杂环境中,腐蚀环境恶劣。为了确保海上塔架式单点钢结构物在整个设计寿命周期内正常服役,通过增加金属材料的腐蚀余量、涂层防腐以及阴极保护等手段达到防腐的目的。
The offshore tower yoke single point mooring(SPM) system is exposed to the complex corrosive environment of seawater, sea mud and marine atmosphere. In order to ensure the normal service life of offshore tower yoke SPM steel structure, several measures including corrosion allowance increase of metal materials, coating anticorrosion and cathodic protection are made to achieve good anticorrosion.
