The tank test is a test to confirm whether the actual ship satisfies the designed performance by using a model ship that reduced the size from actual ship. In hull form development, a tank test is conducted in two stages of hull form improvement test and performance check test. Then, the optimum hull form satisfied with design specifications is derived. In model ship manufacture, we pay close attention to handling your precious hull form data. And we have been making consistent manufacture from lines drawing to model ship cutting.

船型開発の一例

Hull form development of general merchant ships, fishing vessels, working vessels for short term & low cost. More than 55 vessels annually, more than 2,400 vessels in all( in 2018).
