PROBLEM TO BE SOLVED: To provide a reinforcement structure of a vertical waveform bulkhead free from fatigue crack. SOLUTION: This reinforcement structure 20 of the vertical waveform bulkhead comprises a ship side vertical bulkhead 3 of double structure, and a box structure formed by a gusset plate 21 of predetermined height h1-h2 from an inner bottom plate 4 and a shader plate 22, on the whole valley part 5a of a first vertical waveform bulkhead 5 from the vertical bulkhead 3, the gusset plate is mounted in a ship side double tank 16 through the vertical bulkhead 3 to form a partial ship side traverse beam 23. Whereby, the structural weak point that the fatigue crack is found on the vertical waveform bulkhead 5, can be prevented.
