Offshore Wind Power
What is floating offshore wind power?
Unlike the fixed type in which the turbine is installed on a foundation fixed to the seabed, the turbine is installed and operated on a floating body. It can be installed in the deep sea more than 60m, so it can utilize the excellent sea resources of the distant sea, and it is relatively free from location restrictions, so it has the advantage that it is possible to create a large-scale complex.
Floating offshore wind power is expected to play an important role in realizing 2050 carbon neutrality in Korea, which is surrounded on three sides by the sea, in that it exceeds the existing method and utilizes even distant sea resources.
Ulsan, which once enjoyed a revival with the world's No. 1 shipbuilding infrastructure, is preparing to rise again based on natural conditions and shipbuilding/offshore plant echnology and infrastructure. Movement for industry is accelerating.
”Ulsan will leap from the industrial capital in the era of fossil fuels to the industrial capital in the era of clean energy”
Floating body type | Spar-buoy | Semi-Submersible | Tension Leg Platform |
Required marine equipment | semi-submersible fleet, barge, lift crane | A tugboat | Similar to tugboat, spa type |
Stability | ballasting | buoyancy | high stability but high mooring equipment cost |
Manufacturing difficulty | cylindrical structure | most complex welds | relatively simple welds |
Turbine assembly site | deep water depth (more than 100m) | construction port | construction port |
Characteristics | little movement by waves | low required depth of water | fixed to the seabed with a tensioned mooring line |
Type | Catenary | Taut-leg | Semi-taut |

mooring line method | Chain | Rope | Chain + Rope |
mooring radius | large (within 600m) | small (below 100m) | medium (within 500m) |
Installation difficulty | simple | complex (tension required) | medium |
potential risk | Inducing changes in the seabed with a large footprint (environmental impact) |
Highest risk of breaking the mooring line due to high tension |
Moderate risk of suspension and tension angles |
