Energy

With climate change and the depletion of natural resources being recognized as a threat to the survival of humankind,
new renewable energy is attracting more and more attention.
Hyundai Motor Group has been developing the next-generation renewable energy industry that uses tides,
winds, solar power, and geothermal energy as the new driving force for future growth utilizing
its world-class structure designing, building, and installation capabilities.

Offshore Wind Power, Blow the Blue Wind

Offshore wind power is gaining popularity as a key renewable energy source,
due to its advantages in that there are abundant wind resources and the conditions for building large-scaled wind farms are more favorable compared to land-based wind farms.
With past experience in marine constructions, Hyundai Motor Group has been developing optimized technologies for offshore wind power and responding to the growth and changes in the offshore wind power market proactively.

An offshore wind tower is composed of the superstructure, which comprises a wind turbine, blades and a tower, and the substructure that supports it.

The substructures, often called foundation structures, transfer the loads of the superstructures to the ground and make the whole structure stand stably. There are several types of foundation structures, such as monoplies, gravity foundations, jackets and others. Of them, the best type for a project is chosen in consideration of the capacity of the wind turbine, water depth, soil conditions and the environments for construction works. It takes a lot of effort and a great deal of equipment to build structures that are more than 100 m in height and weigh 1000 tons in a sea area which is tens of meters deep and several dozens of kilometers away from the shore.

Key Tech

  • Integrated load assessment and Jacket design for optimized design and construction of foundation structures

    • Integrated analysis and assessment of all the effects from the structures and the environments to the foundation structures.
    • Optimization of jackets and foundations for large wind turbines in deep water, and construction engineering.
  • Suction bucket foundations for reducing construction period and minimizing noise and sediment suspension

    Suction bucket foundations for reducing construction period and minimizing noise and sediment suspension

    • Suction bucket foundations have the shape of overturned buckets that have closed tops and open bottoms. They are pushed into the seabed by the pressure difference which is generated when the water inside is pumped out. This mechanism enables environmentally friendly installation of large foundations without causing noise and sediment suspension.
    • Technology development through offshore field tests and a demonstration project of offshore met mast, aiming application at offshore wind foundation structures.
