PURPOSE:To convey multiple cargos with the same hull by forming water-tight tanks with a hulkhead in the longitudinal direction of the hull, loading a cargo in one tank, rolling the hull so that this tank becomes a lower layer, and cruising with the upper tank left vacant. CONSTITUTION:A hold 3 is divided into two water-tight tanks 7, 8 with a longitudinally formed bulkhead 6. Hatches 9-11 are provided on the tanks 7, 8 and bulkhead 6. A cargo of one type is loaded in one tank 7, and a hull is rolled so that this tank becomes the lower layer. The upper-layer tank 8 is left vacant, and the cargo is conveyed with the hull kept erected. Accordingly, cargos of multiple types can be conveyed with the same hull.
