Shell Expansion


In maritime context, shell expansion refers to the process of increasing the size of a ship's hull by adding new sections or plates to its existing structure. This is done to increase the cargo capacity or to accommodate larger machinery. Shell expansion is a complex process that requires careful planning and execution to ensure the structural integrity of the ship is maintained. It involves cutting the existing hull, welding new sections or plates, and then reinforcing the entire structure to ensure it can withstand the stresses of the sea. The process is typically carried out in dry dock, where the ship can be lifted out of the water and the work can be done in a controlled environment.
