摘要

Provided is a locking apparatus for a damping device of a moonpool, which can automatically lock and unlock an opened state of the damping device of the moonpool. The locking apparatus includes: one or more first locking members installed in a sidewall of the moonpool; one or more second locking members installed in a side of the damping device; and a holding unit separably holding the first locking members and the second locking members when the damping devices are in the opened state.

主权项

1. A marine structure comprising:
a moonpool comprising a sidewall and a moonpool opening for accessing water under the marine structure; a locking shaft arranged generally along a vertical direction; an actuator configured to cause the locking shaft to move back and forth along the vertical direction; a pair of guide plates attached to the sidewall and extending in parallel along the vertical direction with an elongated gap therebetween for accommodating a mid-portion of the locking shaft within the elongated gap; a through-hole guide member attached to the sidewall above the guide plates in the vertical direction and comprising a through-hole configured to pass the locking shaft therethrough; a moonpool door connected to the sidewall and configured to hingedly move between an open position and a close position, wherein the door is configured to stand against the sidewall at the open position and to face water at the close position; the moonpool door comprising a slanted top located at the moonpool door's top and slanted relative to the sidewall to provide a space between the sidewall and the slanted top when the moonpool door is at its open position standing against the sidewall; and a through-hole lock member comprising a through-hole and attached to the slanted top of the door, wherein when the moonpool door is at its open position standing against the sidewall, the through-hole of the through-hole lock member becomes aligned with the through-hole of the through-hole guide member along the vertical direction such that the through-hole of the through-hole lock member receives a tip portion of the locking shaft below the guide plates in the vertical direction.
