  • Recently, new shipbuilding yards with medium capacity are established due to influence of prosperous condition no shipbuilding industry in Korea. These shipbuilding yards have characteristics such as high capacity facilities and followed system of dock launching just like major shipbuilding yards. The present paper explains the dry dock design and structural strength analysis by using FEM. The design stage used TRIBON M3 system while the estimation of structural strength used ANSYS Multiphysics module. The dry dock gate did not frequently open and close, it had to sustain against external wave load during building a ship. Moreover, documents related to design of dry dock gate have no guidelines about design criterion and process of structural strength calculation. It is necessary to make the guidelines about design of dry dock gate. It is expected that this paper will be a good reference to the design of dry dock gate.

  • In most shipyards Floating Dock-gate System is adapted for dry docks. For the safe launching of ships in dry docks, smooth operation of dock-gate must be guaranteed. So it is very important to grasp its behavior in waves for securing the high productivity and the safety of workers. Its seakeeping ability was estimated numerically at the floating conditions and the free roll decay and the seakeeping model tests of dock-gate was carried out with bilge-keels of 3 different widths which have a scale of 1 to 20. More than 20% decrease of roll motion was observed in irregular beam seas by applying a bilge-keel system to the dock-gate that is long and narrow.
