Research | FLOWCON（Floating Offshore Wind Construction System Technology Research Association）

FLOWCON will aim at achieving large-scale and rapid construction of floating offshore wind at a reasonable construction cost, while ensuring construction productivity, reliability and safety comparable to bottom-fixed construction. To this end, FLOWCON will undertake the joint research and technological development of: 1. Studies on rational construction systems for floating offshore wind, 2. Development of technologies required for wind turbine installation at the offshore work base, and 3. Development of metocean prediction system for offshore wind construction.

Construction Flow and Research Themes

This is a conceptual drawing of floating offshore wind construction. A typical construction flow is as follows: ➀Substructure fabrication, ②Substructure assembly, ③Launching, ④Temporary storage, ⑤Substructure towing, ⑥Wind turbine temporary storage, ⑦Wind turbine installation, ⑧Wind turbine/substructure towing, ⑨Wind turbines/substructures temporary storage, ⑩Moorings and anchors, and ⑪Subsea cables. For ⑦Wind turbine installation, we have a offshore work base plan in which wind turbines will be installed offshore. We would study the necessity of such base.
