特殊海域桩基式海洋平台打桩噪声控制技术研究

Research on Pile Driving Noise Control Technology for Pile Foundation Offshore Platforms in Special Sea Areas

以香港地区液化天然气接收站11套导管架海上安装项目为依托,经过前期调研及噪声控制设计,通过打桩窗口及区域控制、打桩工艺控制、水上水下控制等一系列方法,形成了一套完善的导管架海上安装水上、水下噪声控制方案。同时,掌握了桩基式海洋平台打桩噪声控制技术,最终成功应用到11座桩基式海洋平台的安装施工中,为同类型的噪声控制难题做了充足的技术储备。

This article relies on the 11 sets of offshore installation projects of Hong Kong liquefied natural gas receiving stations.After preliminary research and noise control design,a complete set of offshore installation of jackets has been formed through a series of methods such as pile driving window and area control,pile driving process control,and water and underwater control Underwater noise control plan.At the same time,we have mastered the noise control technology for pile foundation offshore platforms,and have successfully applied it to the installation and construction of 11 pile foundation offshore platforms,providing sufficient technical reserves for similar noise control problems.
