With the development of naval ship, many loading crafts with small displacement are replaced. However, it can be reused in coastline and multi-islands areas by improving carry capacity because the retired ships have excellent performance and unique construction. Therefore, how to transform a loading ship with small displacement into a civil carrier with large capacity was discussed. A three-dimensional ship model was established in MAXSURF, and the idealistic transformed model could be obtained by static stability calculation. Then, the model was verified by IMO regulation in stability at large angles of inclination. The total longitudinal flexural strength of the craft in sagging and hogging condition and the local strength were calculated and tested in detailed. The results show that to increase the principal dimensions of the landing craft can improve the carrying capacity successfully, which is an economic, convenient and feasible approach and can provide reference for the transformation and reutilization of the retired ships.
