Seigaiha (lit. wave of the blue ocean) is one of the designs found in Hiden Senbazuru Orikata. This model is the uncut version of it. Folding sequence fully diagrammed in 124 steps (not counting repetitions) without complicated "single-step" collapsing. Recommended sheet size is 50cm+. In theory, one could repeat the pattern and folding method of this model to fold even a thousand orizuru from a single sheet. This model was designed independently and is different from a few similar designs previously proposed by others.
