Longitudinal Analysis Double Hull CPO Barge Influence Heaving Pitching Couple and Distribution Load

Hi anyone, for the first time, this my final project when i was Bachelor degree in my college. My final Project is talk about Longitudinal Analysis Double Hull CPO Barge Influence Heaving Pitching Couple and Distribution Load. i choose this because Sea Transport as we know is absolutely needed. starting from the need for logistics to transport natural resources. one type of marine transportation which is currently mush in need is CPO Barge. Based Information that requirement standard by the Oil Pollution act of 1990 (OPA'90), the International Maritime Organization (IMO), MARPOL (13F7G) are type of liqid cargo barge is to use a Double Hull. On the Barge has a critical region of the longitudinal strength (longitudinal Force) due to the influence waves.

In general calculation safe dimension of each strength member on the ship can be determined by the ship designer, the burden is on the vessel or internal factors, and stresses and deflection  due to external factors. Also is the value of minimum yield strength  for the stresses and deflection on the external load, the load at the extreme wave load analysis is the result Hogging and shagging ,besides that the heaving pitcing couple encounter towards 0 and 180, as well as loading a specific load of ballast during loading and unloading. With the condition of 3rd sea state  variations waves of 0.5 to 2.5. Numerical analysis using finite element method.
