Rotating construction platform based on monopile

Abstract

The present disclosure relates to a rotating construction platform based on a monopile, including a rotary connecting mechanism set on the top of the monopile and a working platform set on the rotary connecting mechanism. The rotary connecting mechanism includes an upper connecting tube, a lower connecting tube and a rotary support structure located between the upper connecting tube and the lower connecting tube. The working platform is fixedly connected to the upper connecting tube, and the lower connecting tube is detachably fixed to the top of the monopile. At least one side of the working platform sticks out of the side of the monopile. The rotating construction platform of the present disclosure can improve the continuity of construction operations, save construction time and costs, avoid vessel machinery from hitting monopile, improve construction positioning accuracy and ensure construction quality.
