Dry Docking a Ship #drydocking #shiprepair #maritime

Dry Docking a Ship is an integral part of ship operation as maintenance and repairs of those parts which cannot be accessed when the ship is in water can only be done in dry docks.

The dry-docking process refers to when a vessel is taken to the service yard and brought to dry land so that submerged portions of the hull can be cleaned and inspected. This work is both preventative as well as a regulatory requirement within the industry.

When the ship enters a dry dock, it must have a positive metacentric height; and is usually trimmed by stern. The floor of the dry dock is lined with keel blocks, which are so arranged such that they can bear the weight of the ship. When the ship enters the dry dock, her centerline is first brought in line with the centerline of the keel blocks by using a combination of plum lines and Leica theodolite.

Excellent content ! Keep making interesting video.I like the animation!

[danielrostek]

Well done, the a lot! But be careful, the CoG does not change when touching the blocks (provided you have no free surface moments). It is the upthrust that is transferred from the CoB to the blocks. However, some literature refers to it as a virtual rise of CoG.
