吸力桶基础安装调平控制系统在长乐海上 风电项目中的应用.

The suction bucket foundation is a non-penetrating shallow foundation with a large diameter and small height, usually sinking by suction, which is more suitable for deep sea areas than traditional mono-piles. The construction of suction bucket foundation has a strict requirement for structural stability and levelness, which make the sinking process complex. So it is necessary to study its control method and leveling strategy further. Relying on the installation and construction project of three-bucket suction bucket foundation in Changle offshore area, this paper analyzes and studies the attitude control process and its control technology and algorithm during suction penetration using the PID control of frequency converter. Based on automatic and manual leveling control processes, combined with the requirements of the bucket penetration depth and the pressure difference limits, an overall control system and on -site construction methods were designed in order to ensure the safety and accuracy of the construction.
