1月12日凌晨5点,中交一航局华能汕头勒门(二)海上风电场项目顺利完成了首根7号风机基础钢管桩沉桩施工,标志着粤东海域在建单体容量最大风电场拉开施工序幕。
海上施工风险重重,需要综合考虑海上天气、海底地质等多种因素。本次施工的7号风机基础钢管桩桩长94.3米,桩径8.0米至9.0米,总重量达1802吨。作为粤东海域首个冬季进行大管径单桩施工项目,华能汕头海上风电公司严格按照“一机一方案”,精心组织施工单位、设计单位、监理单位从地质条件、区域海况、船机起重能力、沉桩可打性分析等方面全方位讨论评审,制定有针对性的安全、质量方案控制措施,并进行表单化桌面推演,施工过程中克服冬季海况恶劣、窗口期短、涌浪大等困难,安全顺利沉桩,实现项目建设“开门红”。
据介绍,华能汕头勒门(二)海上风电项目位于南澳岛南侧海域,建设规模59.4万千瓦,将安装54台11兆瓦风电机组,总投资约82亿元,计划2023年9月份前全容量并网。该项目集约、节约用海指标达到广东省领先水平,预计建成后年均发电量20亿千瓦时,节约标煤约65万吨,减少二氧化碳排放约180万吨,将有效发挥汕头海域新能源富集地区优势,实现清洁电力大规模消纳,为粤东区域能源绿色发展提供“华能经验”,打造“汕头样板”。
