The invention provides single tubular pile base equipment of an offshore wind generating set. The single tubular pile base equipment of the offshore wind generating set comprises a tubular pile, a transition section, circumferential direction shear keys, and a grouting layer, wherein the transition section is sleeved on the upper portion of the tubular pile, the lower portion of the tubular pile can be inserted into a seabed, the grouting layer is filled between the tubular pile and the transition section, and the circumferential direction shear keys are fixed on the tubular pile outer wall and / or the transition section inner wall in a multilayer mode at intervals along the axis direction of the tubular pile and are buried in the grouting layer. Due to the fact that the circumferential direction shear keys are arranged on the tubular pile outer wall and the transition section inner wall and the circumferential direction shear keys are buried in the grouting layer, so that connection strength of the tubular pile and the transition section is increased, vertical force, horizontal bending moment and torsional moment transmitted from the transition section are effectively transmitted to the tubular pile and then to the seabed, and manufacturing cost of basic single tubular pile base equipment of offshore wind generation is reduced.
