Tugboat Ship Stability Excel Calculation

Ship Stability is an area of Naval Architecture

A Jack-Up Platform is a floating barge that has movable legs attached to the hull. These legs can be retracted and extended vertically, meaning that once it makes contact with the sea bed, the platform begins to move upwards and out of the water.

The hull on which these legs are built is water-tight, buoyant, and similar to a ship. It has ballast tanks, living spaces (if required), a bridge for operators to work from, and machinery for lowering and raising the legs. Jack Up refers to how the legs are jacked up or down.
