Indonesia’s geograpycal is archipelago. As archipelago, Indonesia has been recognized world by internationally. Srategic conditions in Indonesia demand that the county is able to develop the potential of the maritime. One of the efforts in develelopment about maritime potential is one of them is manufacture model dry dock gate is stable. Dry Dock Shipyard Door Modeling is used to carry out the analyzes needed by the research and also wants to promote the use according to the needs of the field, both in terms of safety, comfort and budget in terms of operational safety. This research program aims to resolve the stability of Dry Dock doors with a length of 40.4 meters using Maxsurf and Hydromax software in analyzing estimates using intervals of 500 mm in length expected to produce detailed data leading to longitudinal and transverse data as asked by the process ship planning in general. The result of dry dock gate analysis with a length of 40.4 m meets IMO standards where ballast construction requires 54% and 68% and using ballast fix will be able to produce a GMt value of 1.693 m with a tide height of 10.393 m. GMt values indicate the gate dick can remain stable and sturdy standing at the bottom of the dock when dry. when the ballast is empty, it will produce GMt 1,007, which means the dock is stable, but it is still easily broken down. These conditions govern when maintaining dry dock doors
