4月21日，天津港集团港航工程公司“第四代+”自航自升式海上风电安装平台“港航平5”完成桩腿接长关键升级，桩腿长度达到140米，创下国内海上作业平台桩腿长度新纪录。
据介绍，“港航平5”是代表目前国内海上施工装备最高水平的“大国重器”，2024年8月交付。平台最大起重能力达1800吨，配备四桁架桩腿与齿轮齿条式升降系统，搭载DP2动力定位系统，具备国际无限航区航行能力，是国内综合性能最强的海上施工平台。
本次升级在完成桩腿接长的同时优化升降系统、结构强度与作业稳定性，使平台深远海适应能力和多场景作业能力显著提升，刷新同类装备作业水深极限。升级后，平台不仅可高效完成目前最大海上风机安装，还能满足未来深远海风电开发与海洋油气工程作业需求。
