Concept Design and Analysis of TWD Motion Compensated Pile Gripper

More Info


Nowadays, as it is a easy sequence in construction and installation, the monopile is the most common used support structure. Due to the limitation of water depth and lifting capacity, jack-up vessels gradually become unable to fulfill the demands of monopile installation. Floating vessels can expand the market of wind farminstallation due to the larger lifting capacity and higher cost-effectiveness. However, the main difficulty is that vessel motions will result in excessive monopile response, which is not conducive to monopile installation. To overcome this difficulty, TWD introduced the concept of the Motion Compensated Pile Gripper, which aims to restrict monopile motions in order to allow it to be installed through a floating vessel.
