Detailed Design (facility design, structural design), Construction Plan)
Construction(construction supervision)◆Procedure◆Determine designed wind and wave conditions to be used forstructural design of OWT facilities. (On site wind and wave
surveys need to be implemented separately.)◆Determine site specific geological conditions where OWTs
are situated.
◆Carry out economical structural design using designed wind,
wave, geological, and seismic conditions.
◆Pursue best Generation & Costs ratio analysis by iteratingcase studies of different arrangement of OWTs position.
◆Provide continued support for approval process of relevantlaws until satisfactory results are acquired.

Onshore Transmission Line ●Design of transmission towers and underground transmission line facilities◆Support of selecting suitable site for wind turbines
Suitable site will be recommended by taking into consideration ofsocial and environmental conditions, requirement by various
regulations, and local opinions.
【Case 1】Study on the suitable site for the offshore wind power
turbines in the Akita port and the Noshiro port (Akitaprefecture)【Case 2】Pilot project promoted by the initiative of local
municipality for determining suitable site (led by Goto
city in collaboration with Ministry of the Environment)【Case 3】Environmental impact assessment of the wind power

Planning◆Methods of Analysis“SESAM” is used for structural analysis of fixed OWTsubstructure at following limit states;◆Ultimate limit states design
Structure is designed to withstand designed forces such as wind
and wave conditions with a 50-year return period, Level 1 & 2
earthquake ground motions, and tsunami forces.
◆Fatigue limit states design
Optimal specifications of steel structural member are determinedbased on accumulated fatigue damage analysis through project
lifetime.
