[0002] Jacket platforms, also known as piled platforms, are supported by piles driven into the seabed. They are designed to withstand external forces such as wind, waves, and currents. Jacket platforms can be categorized as pile clusters, pile foundations (jacket platforms), and leg-column platforms. Jacket platforms primarily consist of four components: the jacket, piles, jacket cap, and deck. They offer strong adaptability, safety, reliability, simplicity, and low cost.

[0003] The pile gripper prevents the monopile from uncontrolled shaking during lowering and driving, and keeps the monopile vertical by compensating for the horizontal movement of the vessel.
