Kamisu Nearshore Wind Farm - phase 2

Location

The Kamisu Nearshore Wind Farm is located off the coast of Ibaraki Prefecture in Japan, specifically in the Kashima-nada area.

Developer and Operator

The wind farm was developed and is operated by Wind Power Ibaraki.

Phase Details

Phase 1

• This phase consists of 7 turbines, each being Subaru 80/2.0 models with a power output of 2,000 kW (2 MW) and a diameter of 80 meters. The total nominal power for Phase 1 is 14,000 kW.

Phase 2

• This phase includes 8 turbines, also using the Subaru 80/2.0 models, each with a power output of 2,000 kW (2 MW) and a diameter of 80 meters. The total nominal power for Phase 2 is 16,000 kW.

General Data

• Latitude and Longitude: 35° 53' 46.1" N, 140° 43' 33.8" E.
• Depth: The turbines are installed in waters with a depth of approximately -5 meters.

Turbine Specifications

• Turbine Model: Subaru 80/2.0
• Power Output: 2,000 kW (2 MW) per turbine
• Diameter: 80 meters
• Hub Height: Not specified in the sources provided.

Operational History

• The Kamisu Nearshore Wind Farm, including both phases, has demonstrated resilience. For instance, during the 2011 Tohoku earthquake and tsunami, the wind farm shut down temporarily due to the tsunami affecting a nearby sub-station but resumed normal operation shortly after.

Other Relevant Information

• The wind farm is notable for its ability to withstand significant seismic activity. Despite the intense shaking during the 2011 earthquake, the turbines experienced no mechanical trouble and were quickly back online.
• The turbines are supported by monopile foundations, which are designed to handle the seismic conditions of the region.
