Abstract:

Provided is a damping apparatus for a moonpool, which has a simple driving mechanism. The damping apparatus includes one or more damping plates which cover a moonpool of a hull entirely or partially. The damping plates are pivotally hinged to a sidewall of the moonpool, and one or more conveying units are disposed above the moonpool to convey drilling equipment. Driving wires are coupled between the conveying units and the damping plates, and the conveying force of the conveying units is transferred through the driving wires to the damping plates. Thus, the damping plates are pivoted to open and close the moonpool entirely or partially.
