| Abstract: | With the development of the ocean engineering, derrick barge ships become larger and larger. The derrick barge ships' B/T is greater than the general ships' B/T. Based on the derrick barge ship's character of ultra shallow draft, this paper calculates the hydrodynamic coefficient for every degree of freedom on the condition of the general ocean environment. All of these studying are very important to analyze the hydrodynamic coefficient of the derrick barge ship for estimating its movement and security. |
