ULSAN, South Korea — Offshore wind is beginning to look less like a standalone renewable-energy industry and more like one component of a much larger energy infrastructure system.
That shift was visible on September 22 at the Sweden–Korea Supply Chain Day for Floating Offshore Wind, held at Lotte Hotel Ulsan.
The event brought together representatives from the Embassy of Sweden, Business Sweden, the MunmuBaram floating offshore wind project, Ulsan Metropolitan City, Korean manufacturers, logistics companies and energy-technology providers.
Rather than focusing only on wind turbines, the discussion extended across the wider offshore wind supply chain — from floating structures, cables and ports to transmission, hydrogen, data centers and industrial electrification.
Building a Korea–Sweden Offshore Wind Supply Chain
At the center of the cooperation is MunmuBaram, a major floating offshore wind development planned off the coast of Ulsan.
The project is designed for deep offshore waters approximately 65 kilometers from the coast, where floating foundations can enable wind generation in areas that are less suitable for conventional fixed-bottom structures.
The project concept represents approximately 750 MW of offshore wind capacity and illustrates the industrial scale at which Korea's floating offshore wind market could develop.
But the significance of MunmuBaram goes beyond electricity generation.
The wider Korea–Sweden initiative aims to connect international offshore wind expertise with Korea’s established capabilities in shipbuilding, heavy fabrication, electrical cables, marine engineering, ports and logistics.
Cooperation around the project includes areas such as subsea and power cables, offshore structures, manufacturing, transportation and port logistics.
For Korea, this is important because offshore wind farms may operate at sea, but much of their economic value is created on land — in factories, shipyards, cable plants, engineering companies and ports.
Sweden Brings Technology, Korea Brings Industrial Scale
The partnership reflects the complementary strengths of the two countries.
Sweden brings experience in renewable energy, offshore wind development, power systems, engineering technology and energy transition.
Korea brings globally competitive capabilities in shipbuilding, offshore structures, steel fabrication, electrical cables, heavy machinery and large-scale industrial manufacturing.
The goal is therefore not simply to import wind turbines or foreign technology.
It is to create an industrial ecosystem in which Korean manufacturers, ports and engineering companies participate directly in the construction, installation and operation of large-scale offshore wind projects.
For Ulsan, this creates a potential bridge between its traditional strengths in shipbuilding, offshore engineering and energy and the next generation of renewable infrastructure.
Offshore Wind Is Becoming Part of a Much Larger Energy System
One of the most revealing presentations at the event came from Hitachi Energy.
Rather than showing offshore wind as an isolated source of renewable electricity, the presentation placed renewable generation at the beginning of an integrated energy value chain.
The system connected offshore wind, onshore wind and solar generation with transmission and distribution infrastructure and then with a range of future electricity users.
Among those users were industry, hydrogen production, data centers and transportation.
This broader picture is increasingly important because the energy transition is no longer simply about replacing one source of electricity with another.
It is also about determining how new electricity generation will connect to the industries that will consume enormous amounts of power in the decades ahead.
AI Data Centers Enter the Energy Equation
AI data centers are becoming one of the clearest examples of this new electricity demand.
The rapid deployment of GPU-based computing infrastructure is increasing the importance of reliable power supply, high-capacity transmission networks and long-term energy planning.
Offshore wind alone cannot provide the constant electricity profile required by a large AI data center. Wind generation is variable and must operate within a wider system that can include the grid, energy storage, dispatchable generation and other balancing resources.
But large-scale offshore wind can become an increasingly important part of the regional electricity portfolio supporting future digital infrastructure.
The relationship can be viewed as:
Offshore Wind → Power Grid → AI Data Centers → Digital Industry
There is also another possible pathway:
Offshore Wind → Electricity → Hydrogen → Industry & Transport
The important point is not that every offshore wind farm will directly power a data center or hydrogen plant.
It is that renewable generation, transmission, hydrogen, industrial electricity consumption and computing infrastructure are increasingly becoming part of the same regional energy planning challenge.
MunmuBaram Shows How Long the Development Cycle Can Be
The MunmuBaram presentation also illustrated the long development cycle required for large floating offshore wind projects.
Its project schedule shows a sequence that begins with supply-chain preparation and wind-auction participation, followed by engineering, contracting, permitting and stakeholder coordination.
The schedule indicates a wind auction stage in 2026, an offtake contract milestone around 2027 and a targeted Final Investment Decision, or FID, around 2029.
It also illustrates an approximately 78-month construction period leading toward a targeted Commercial Operation Date, or COD, in 2033.
Alongside those major financial milestones, the development process includes FEED, geophysical and geotechnical studies, detailed design, turbine and floater engineering, permitting, fisheries-related consultation and construction approvals.
The timeline demonstrates an important reality of offshore wind.
A project does not begin when turbines are installed at sea.
It begins years earlier through engineering work, permitting, supply-chain preparation, local consultation and financial commitments.
This is why long-term policy visibility is important not only to developers but also to shipyards, cable suppliers, ports and component manufacturers that must invest in capacity well before commercial operation begins.
Korea’s Offshore Wind Market Is Moving Toward Scale
South Korea has historically had a large offshore wind development pipeline but relatively limited operating capacity.
That gap is now beginning to narrow as government policy shifts toward larger and more predictable auction volumes.
In the first half of 2026, nine offshore wind projects totaling 3,656 MW participated in Korea’s fixed-price competitive bidding process.
Five projects totaling 1,786 MW were selected.
Of that capacity, approximately 1,254 MW came from fixed-bottom offshore wind while 532 MW came from floating offshore wind.
The return of floating offshore wind to Korea’s commercial auction process is particularly relevant to Ulsan, where deep coastal waters make floating foundations an important option.
Korea Sets a 25 GW Offshore Wind Target
Korea is also developing a longer-term market framework for offshore wind.
The 2026–2035 offshore wind bidding roadmap calls for more than 4 GW of auctions annually and approximately 55 GW of total auction volume over ten years.
The roadmap targets 10.5 GW deployed or under construction by 2030 and 25 GW of cumulative offshore wind capacity by 2035.
| Period / Target | Offshore Wind |
|---|---|
| 2026–2035 auction volume | 55 GW |
| Annual auction volume | 4 GW+ |
| 2030 deployed or under construction | 10.5 GW |
| 2035 cumulative deployment | 25 GW |
For equipment suppliers and industrial manufacturers, those numbers matter because offshore wind requires production capacity years before electricity begins flowing.
Foundations must be fabricated, cables manufactured, vessels secured, port capacity prepared and large components transported and assembled.
The Offshore Wind Turbine Is Getting Much Bigger
The physical scale of offshore wind technology is also changing rapidly.
Only a few years ago, an 8 MW turbine represented advanced commercial offshore technology.
The industry has since moved through the 10 MW and 11 MW classes toward 14 MW and 15 MW machines.
Siemens Gamesa’s offshore turbine portfolio reflects this progression from the SG 8.0-167 to the SG 11-200, SG 14-236 and the newer SG 15-236.
The SG 15-236 has a nominal capacity of 15 MW and a rotor diameter of approximately 236 meters.
Vestas has similarly developed the V236-15.0 MW, using blades more than 115 meters long.
The direction is clear: future offshore wind farms can generate significantly more electricity with fewer individual turbines.
But larger turbines also create greater engineering challenges.
They require larger foundations or floaters, greater mooring loads, heavier components, higher-capacity cranes, stronger ports and more sophisticated installation vessels.
Digital Manufacturing Becomes Part of the Supply Chain
The increasing size and complexity of offshore wind equipment also explains why digital manufacturing and quality control were important topics at the Ulsan event.
For very large offshore structures, assembly is no longer only about mechanically joining components.
Torque values, fastening sequences, operator records, tool calibration and assembly data can all become part of a digital quality record.
That information can later support inspection, maintenance and lifecycle management.
The offshore wind manufacturing chain is therefore evolving toward:
Digital Assembly → Quality Data → Traceability → Predictive Maintenance → Lifecycle Management
This represents another area where Korea’s shipbuilding and offshore industries can potentially transfer decades of industrial experience into renewable-energy infrastructure.
Why Ulsan Matters
Ulsan occupies a particularly interesting position in this transition.
The region already combines shipbuilding, offshore engineering, petrochemicals, automotive manufacturing, power infrastructure and major port facilities.
That means many of the industrial capabilities required for floating offshore wind already exist within the wider southeast Korean manufacturing ecosystem.
If large-scale floating projects progress into commercial construction, the opportunity could extend well beyond the wind turbine itself.
Floating foundations, mooring systems, dynamic cables, offshore substations, installation vessels, ports, digital tools, maintenance services and logistics could all become part of a new industrial ecosystem.
From Wind Farms to Energy Infrastructure
Offshore wind is now entering a different phase.
The first phase was about proving that large turbines could generate electricity reliably at sea.
The next phase is about industrial scale.
And scale changes the conversation.
It becomes a discussion about ports, vessels, factories, cables, transmission networks, hydrogen production, digital manufacturing and increasingly the electricity requirements of artificial intelligence.
For Korea, offshore wind therefore has the potential to become more than a renewable-energy policy.
It can become part of a broader industrial and energy infrastructure strategy.
The Korea–Sweden cooperation now developing around Ulsan provides an example of what that transition could look like: combining international renewable-energy expertise with Korea’s industrial manufacturing capacity.
The emerging energy value chain can increasingly be understood as:
Offshore Wind → Grid → Hydrogen → AI Data Centers → Industry
For Ulsan, the opportunity is therefore not simply to generate electricity offshore.
It is to build the industrial ecosystem around that electricity — and potentially connect renewable generation to some of the most power-intensive industries of the coming AI era.
