| Abstract: | Fatigue load, load case and combination factor for Type-C independent cargo tank was discussed in this paper. Integration with the design principle of Type-C independent cargo tank, fatigue load case and combination factor was established. Based on the 3-D acceleration ellipsoid method in the new-IGC CODE, the calculation method of fatigue load corresponding to the maximum stress range was given. Load distribution model which recommended by IACS was also introduced. It could be taken as a significant reference to structure fatigue resistance design of Type-C independent cargo tank. |
