Wind Farm Construction

Globally, more than 130 countries are considering or have set net-zero carbon targets. Japan, which has set the goal of achieving carbon neutrality by 2050, has already begun the construction of offshore wind power turbines.

DENZAI’s experience in this sector – among other successes, we were the first Japanese company to be involved in offshore wind power construction in Taiwan – and our position as a market-leader enable us to provide comprehensive solutions to any challenges associated with the building of onshore and offshore wind turbines.

Currently, a large majority of offshore wind farms are fixed-bottom, using large monopiles to hold the structures in place in shallow continental shelves. As nations in Asia and globally embrace the construction of floating wind farms, DENZAI stands as an experienced partner, from the planning stage to installation, operation and maintenance. Our know-how, coupled with our continued investment in heavy equipment, allows us to provide exceptional client solutions as wind farms grow in size and output.

To ensure the continued productivity of wind farms, DENZAI also assists inspections and repairs after construction.

Adapting to the Need for Larger Turbines and Longer Blades

As the need for electricity grows globally, wind turbines are becoming bigger and taller and blades are becoming larger in order to capture more energy. Transporting these larger components presents new challenges: routes can be obstructed by natural features or existing development, requiring meticulous planning and specialized equipment.

In response, DENZAI was the first company to introduce the FTV850 to Japan, a transport standing adapter which can transport blades up to 80 meters in length. Our specialists thoroughly evaluate the project needs, working together to minimize cost and disruption while adhering to strict safety standards.

Planning, Transportation and Construction – Offshore and Onshore

For offshore wind power farms, DENZAI handles the transportation of components to the port, assembly at the port, crane work aboard the SEP vessel and construction work.

For onshore projects, we carry out unloading operations at the port, planning and execution of transportation from the port to the construction site and installation of the wind turbine by crane.
