The Pure Car and Truck Carrier(PCTC) is a ship for transportation of high roof type or heavy vehicles such as recreation vehicles, trucks, trailer, buses and buldozers. The loading and unloading of cargo units is carried out by Roll-on/Roll-off through the stern ramp(or side ramp). Liftable car decks are arranged between some deck levels for the purpose of flexible loading of different height of vehicles on or below the deck. Because of the reason of loading the various kind of vehicles, PCTC has become more popular than the PCC in recent years. PCTC has the structural features of the sufficient longitudinal strength and insufficient transverse racking strength due to limited number of transverse bulkhead. Following analyses have been performed in this study to confirm the structural adequacy of main structural members for 6,500 Unit Roll-On Roll-Off Car Carrier.
· transverse strength analysis based on standard rule loading
· entire ship structural analysis based on dynamic load analysis
· spectral fatigue analysis
In this first paper, the results of transverse strength analysis is reported. In the second paper, the results of entire ship structural analysis and spectral fatigue analysis will be reported.
