## English (EN)
### 1) What “wind turbine manufacturer” means in practice
In the wind industry, “turbine makers” usually refers to **OEMs that design and supply the full wind turbine generator (WTG)**—rotor/blades, hub, nacelle (generator, drivetrain), controls, and often commissioning plus long-term service. Separately, many companies are **major global suppliers of components** (towers, blades, foundations) without being full-turbine OEMs.
---
### 2) Korea’s main turbine OEMs (utility-scale / grid-connected)
#### A. Doosan Enerbility (두산에너빌리티) — Offshore-focused Korean OEM + nacelle assembly hub
* **Product line / positioning:** Doosan presents its on/offshore lineup (e.g., 3.3MW, 5.5MW, and an offshore 8MW class) and emphasizes designs optimized for **Korea’s relatively low wind speeds**. ([두산에너빌리티][1])
* **8MW offshore turbine certification:** Doosan’s 8MW offshore turbine (DS205-8MW class) obtained international certification (Type certification) around the end of 2022, as reported by Doosan and industry media. ([두산에너빌리티][1])
* **10MW offshore turbine (DS205-10MW) type certification:** Doosan announced that it received **type certification from UL** for its 10MW offshore model on **July 23, 2025**, describing this as the first Korean company to secure international certification for a 10MW offshore turbine. ([두산][2])
* **Korean offshore project track record:** Doosan states it has supplied offshore turbines to projects including **Jeju Tamra (30MW, 2017), Southwest Sea (60MW, 2019), and Jeju Hallim (100MW, 2025)**, and positions itself as having a leading domestic track record. ([두산에너빌리티][3])
* **Manufacturing ecosystem / localization push:** Doosan highlights increasing localization and strengthening the Korean offshore supply chain as part of its 10MW program. ([두산][2])
* **Nacelle assembly for global OEM turbines (local content pathway):** Under MoUs related to Equinor/Siemens Gamesa projects, nacelles of large-class turbines are planned to be assembled at Doosan’s **Changwon** facility. This is important because it creates an “industrial base” in Korea even when the turbine model is from a foreign OEM. ([equinor.co.kr][4])
**Practical implication:** Doosan is the clearest “Korean offshore turbine OEM” with publicly documented models and certifications, plus a parallel strategy to be a **Korean nacelle assembly platform** for very large turbines used in floating/offshore projects.
---
#### B. UNISON (유니슨) — Korean OEM expanding toward 10MW offshore
* **OEM identity:** Unison describes itself as a leading Korean wind power company providing solutions and wind farm experience. ([unison.co.kr][5])
* **10MW direct-drive offshore model announcement:** Trade press reports Unison unveiling a **10MW direct-drive offshore** model with a plan to move toward prototype and commercialization timelines. ([rechargenews.com][6])
* **Manufacturing partnership dynamics:** Industry coverage also notes Unison’s collaboration with Mingyang for manufacturing wind turbines in South Korea, reflecting how Korean OEMs may hybridize domestic manufacturing with foreign technology pathways. ([Offshore Wind][7])
**Practical implication:** Unison is a key domestic OEM name to track for offshore scale-up, but procurement requires close due diligence on **serial production readiness**, certification status, and service footprint for the specific model you intend to deploy.
---
#### C. Hyosung Heavy Industries (효성중공업) — Historically significant Korean turbine developer (status must be checked model-by-model)
* Hyosung states it developed Korea’s first 750kW turbine (2006), 2MW (2009), and installed a 5.5MW offshore turbine (2014) that received international certification from **DEWI-OCC** (2015). ([hyosungheavyindustries.com][8])
* Several industry directories list Hyosung among Korean manufacturers, but some global databases may label certain product lines as not active; this can reflect market reality (limited new sales) rather than corporate existence. ([thewindpower.net][9])
**Practical implication:** Hyosung matters for the history of Korean turbine development and certification. For new projects, confirm current commercial offerings, turbine platform availability, and long-term O&M capability.
---
### 3) Smaller / specialized Korean turbine makers (distributed, low-wind, hybrid use cases)
#### Enerwin Korea (에너윈코리아) — Small/medium “S-SAWT” wind turbines
* Enerwin positions itself around **small/medium wind turbines** with a distinctive blade design and claims performance at low wind speeds; it also references patents and certifications and mentions KS-related progress and public-sector designations in its materials. ([에너윈코리아(주)][10])
* This segment is typically relevant to **microgrids, islands, industrial sites, telecom power, and hybrid solar-wind**—not to GW-scale offshore arrays.
---
#### Global Wind Energy (GWE, 글로벌윈드에너지) — “WINDAWIND” branded large-scale onshore/offshore development/manufacturing claims
* GWE markets “WINDAWIND” as specialized in development/manufacturing/installation for large-scale onshore/offshore. ([gwe.kr][11])
* Treat such claims as a starting point; validate reference projects, serial production, and certification evidence.
---
### 4) Key Korean supply chain companies that are not turbine OEMs (but are critical)
#### A. Towers and offshore structures: CS WIND (씨에스윈드)
* CS WIND positions itself as a **global manufacturer of wind towers and offshore wind substructures**, headquartered in Korea. ([cswind.com][12])
**Why it matters:** Even if turbines are foreign OEM, towers/substructures can be heavily localized and drive local value-add and logistics feasibility.
#### B. Blades and composites: Human Composites (휴먼컴포지트) + testing ecosystem
* Doosan states its **100m blade** program involved Human Composites (blade manufacturer) with KIMS and testing at a certified facility, illustrating domestic capability in very large blades and structural validation. ([두산][13])
* Human Composites also positions itself as a wind blade-focused composite company. ([humancomposites.com][14])
#### C. Blade material inputs: Kumho P&B Chemicals / Toray Advanced Materials Korea
* Kumho P&B Chemical markets resin/chemical product lines tied to wind turbine blades. ([kpb.co.kr][15])
* Toray Advanced Materials Korea reported an MOU related to building an **offshore wind blade cluster**, reflecting broader domestic industrialization for blades/materials. ([torayamk.com][16])
---
## 5) How to evaluate Korean turbine OEMs (and avoid common failure modes)
Wind projects fail not only on LCOE, but on **bankability, certification, and service**. Use this checklist.
### A. Bankability and certification
* **Type Certification & Design Evaluation:** Confirm IEC 61400 alignment and the specific certifying body (e.g., UL as in Doosan’s DS205-10MW). ([두산][2])
* **Grid code compliance:** Korea’s grid connection requirements can be strict; verify power quality (LVRT/HVRT, reactive power, harmonics) with the utility/interconnection study.
### B. Korea-specific environmental engineering
* **Typhoon / turbulence / complex terrain:** Korea’s coastal/offshore sites can demand conservative load cases. Confirm extreme wind, wave, and lightning design assumptions; do not accept generic European North Sea settings without local validation.
* **Low-wind speed optimization:** Both Doosan and Enerwin explicitly emphasize low-wind performance narratives; translate that into measurable curves (power curve, AEP at site Weibull). ([두산에너빌리티][1])
### C. Service (O&M) and spare parts
* Evaluate: guaranteed response times, blade inspection strategy, gearbox/generator swap logistics, spares warehouse in Korea, SCADA access, and warranty exclusions.
* Offshore: confirm jack-up vessel strategy, weather windows, and major component exchange plan.
### D. Commercial risk controls
* Use staged contracting: **prototype / pilot array → serial order**, with performance warranties tied to independently verified AEP.
* Insist on clear liquidated damages (LDs): availability LDs, power curve LDs, and delay LDs.
---
## 6) Where Korean OEMs fit best today (pragmatic segmentation)
* **Utility-scale offshore in Korea (fixed + floating):** Doosan is the most documented domestic OEM pathway; Unison is the other key name to monitor. ([두산][2])
* **Local content strategy even with foreign turbines:** Nacelle assembly at Changwon is an example of how projects can localize manufacturing while using global OEM platforms. ([equinor.co.kr][4])
* **Distributed / low-wind niche:** Enerwin and other small wind specialists can be relevant where grid extension is expensive or hybrid systems are prioritized. ([Enerwin Korea Inc.][17])

## 한국어 (KO)
### 1) “터빈 제작업체”를 정확히 구분해야 하는 이유
풍력에서 “터빈 제작”은 보통 **WTG(풍력발전기) 완제품 OEM**(로터/블레이드, 허브, 나셀(발전기·구동계), 제어, 시운전·서비스)을 뜻합니다. 반면 **타워·블레이드·하부구조물**처럼 핵심 부품을 만들지만 완제품 OEM이 아닌 기업도 많아서, 발주/조달에서는 이 구분이 매우 중요합니다.
---
### 2) 한국의 대표 터빈 OEM(유틸리티급/계통연계)
#### A. 두산에너빌리티(Doosan Enerbility) — 국내 해상풍력 OEM의 “가장 명확한” 축 + 창원 나셀 조립 거점
* **라인업/포지셔닝:** 두산은 3.3MW, 5.5MW, 해상 8MW급 등 라인업을 제시하며, 한국의 **저풍속 환경 최적화**를 강조합니다. ([두산에너빌리티][1])
* **8MW급 국제인증:** 8MW급 해상풍력 터빈이 2022년경 국제인증(Type certification)을 받았다는 내용이 두산 자료/산업매체에서 확인됩니다. ([두산에너빌리티][1])
* **10MW(DS205-10MW) UL Type 인증:** 2025년 7월 23일, 두산은 **UL로부터 10MW 해상풍력 터빈 Type 인증**을 취득했다고 발표했습니다(국내 기업 최초 10MW급 국제인증이라는 서술 포함). ([두산][2])
* **국내 해상 프로젝트 공급 이력(두산 주장):** 제주 탐라(30MW, 2017), 서남해(60MW, 2019), 제주 한림(100MW, 2025) 등 공급 실적을 제시합니다. ([두산에너빌리티][3])
* **국산화/공급망 확대:** 10MW 프로그램과 연계해 국산화율 확대 및 국내 공급망 육성을 강조합니다. ([두산][2])
* **해외 OEM 대형 터빈의 ‘국내 나셀 조립’ 경로:** Equinor/Siemens Gamesa 관련 협력에서 **창원 공장에서 대형 터빈 나셀을 조립**하는 계획이 명시되어 있습니다. 이는 “한국 내 제조·고용·부품 생태계”를 만드는 핵심 장치입니다. ([equinor.co.kr][4])
**실무 포인트:** 두산은 “국내 OEM + 국제인증 + 국내 조립 거점”의 조합이 가장 분명합니다. 특히 해상(고정식/부유식)에서 국내 공급망을 묶는 역할이 강합니다.
---
#### B. 유니슨(UNISON) — 국내 OEM, 10MW 해상(직구동) 확장 시도
* **OEM 정체성:** 유니슨은 국내 풍력 선도 기업으로 솔루션/프로젝트 경험을 강조합니다. ([unison.co.kr][5])
* **10MW 직구동 해상 모델 공개 보도:** 2024년 9월경 10MW 직구동 해상 모델을 공개했다는 보도가 있습니다. ([rechargenews.com][6])
* **제조 파트너십(기술·생산 결합):** Mingyang과의 국내 제조 협력 보도도 존재합니다(국내 생산과 해외 기술의 결합 모델). ([Offshore Wind][7])
**실무 포인트:** 유니슨은 국내 OEM 축의 핵심이지만, 프로젝트 발주 시에는 **양산 준비도, 인증·시험 단계, 장기 O&M 체계**를 “모델 단위로” 매우 촘촘히 확인해야 합니다.
---
#### C. 효성중공업(Hyosung Heavy Industries) — 국내 터빈 개발/인증 ‘역사’가 있는 기업(현재 판매/라인업은 별도 검증 필요)
* 효성은 2006년 750kW, 2009년 2MW 개발, 2014년 5.5MW 해상 터빈 설치, 2015년 **DEWI-OCC 국제인증**을 소개합니다. ([hyosungheavyindustries.com][8])
* 일부 글로벌 디렉토리에서는 “비활성” 표기가 보이기도 합니다(시장 상황상 신규 판매가 제한적일 수 있다는 의미로 해석될 여지). ([thewindpower.net][9])
**실무 포인트:** “지금 당장 신규 단지에 어떤 플랫폼을 얼마만큼 공급 가능한가”는 별개의 질문입니다. 최신 제품 라인업, 인증, 서비스 체계를 계약 전에 문서로 확정해야 합니다.
---
### 3) 소형/특수 목적(분산형·저풍속·하이브리드) 국내 업체
#### 에너윈코리아(Enerwin Korea) — 소형·중형 S-SAWT 계열
* 에너윈은 저풍속에서의 발전, 특허/인증, KS 관련 진행 및 공공 분야 지정 등 내용을 안내합니다. ([에너윈코리아(주)][10])
* 주 용도는 대규모 해상단지보다 **섬·마이크로그리드·산업부지·통신/비상전원·태양광+풍력 하이브리드** 쪽에 가깝습니다.
#### 글로벌윈드에너지(GWE) — WINDAWIND 브랜드(대형 온·해상 개발/제조/설치 표방)
* GWE는 WINDAWIND를 대형 온·해상 개발/제조/설치/판매로 소개합니다. ([gwe.kr][11])
* 레퍼런스 프로젝트, 양산/납품 이력, 인증 문서가 확보되어야 “실제 OEM”으로 평가 가능합니다.
---
### 4) “터빈 OEM은 아니지만” 한국에서 매우 중요한 공급망(부품/소재/구조물)
#### A. 타워·해상 하부구조물: 씨에스윈드(CS WIND)
* CS WIND는 **풍력 타워 및 해상풍력 구조물(하부구조 포함)** 글로벌 제조사임을 명시합니다. ([cswind.com][12])
#### B. 블레이드/복합소재: 휴먼컴포지트(Human Composites)
* 두산 100m 블레이드 개발에서 휴먼컴포지트가 블레이드 제작사로 참여했고, KIMS 등과 시험·검증을 진행했다는 내용이 두산 발표에 있습니다. ([두산][13])
* 휴먼컴포지트는 자사 역량을 풍력 블레이드 중심의 복합소재 회사로 소개합니다. ([humancomposites.com][14])
#### C. 블레이드 소재(수지/섬유·클러스터): 금호P&B, 도레이첨단소재
* 금호P&B는 풍력 터빈 블레이드 관련 소재/수지를 제품군으로 안내합니다. ([kpb.co.kr][15])
* 도레이첨단소재는 해상풍력 블레이드 산업 클러스터 관련 MOU 소식을 공개했습니다. ([torayamk.com][16])
---
### 5) 발주/도입 시 실패를 줄이는 “실전 체크리스트”
1. **인증의 종류를 분해해서 확인**
* Type Certification(형식인증), Design Evaluation(설계평가), 부품 인증(블레이드, 제어, 타워 등)
* 예: 두산 DS205-10MW는 UL Type 인증 취득을 발표. ([두산][2])
2. **AEP(연간발전량) 검증 방식**
* 저풍속 최적화는 문구가 아니라, 사이트 Weibull/난류/전단 기준으로 AEP·가동률을 제3자가 검증해야 합니다. ([두산에너빌리티][1])
3. **해상 O&M 체계**
* 예비품 창고(국내), 주요부품 교체 리드타임, 선박/기상창(Weather window), 가동률 보증(Availability) LD 구조
4. **계통연계(Grid Code)**
* LVRT/HVRT, 무효전력, 하모닉 등은 EPC·계통연계 단계에서 가장 많이 문제를 일으키는 포인트입니다.
5. **계약 구조로 리스크를 고정**
* 파일럿 → 본단지(양산) 단계 계약
* 성능보증(파워커브)·가동률·납기 지연에 대한 LD를 문서화

## Français (FR)
### 1) Définition opérationnelle d’un “fabricant de turbine”
Dans l’éolien, un “fabricant de turbine” désigne généralement un **OEM** qui fournit l’aérogénérateur complet (rotor/pales, moyeu, nacelle, chaîne de conversion, contrôle, mise en service et service). Les fabricants de tours, pales ou fondations peuvent être essentiels sans être OEM de turbine complète.
### 2) Principaux acteurs coréens côté OEM (utilité / réseau)
* **Doosan Enerbility** : met en avant des machines adaptées aux conditions coréennes (notamment la performance en vents plus faibles) et a annoncé la **certification de type UL** pour sa turbine offshore **DS205-10MW** (23 juillet 2025). ([두산][2])
Par ailleurs, des accords industriels prévoient l’**assemblage local de nacelles à Changwon** pour de très grandes turbines offshore, ce qui structure une filière locale même lorsque la plateforme turbine est étrangère. ([equinor.co.kr][4])
* **UNISON** : la presse sectorielle rapporte la présentation d’un **modèle offshore 10 MW direct-drive**. ([rechargenews.com][6])
* **Hyosung Heavy Industries** : la société décrit ses développements historiques (750 kW, 2 MW, 5,5 MW offshore) et une certification DEWI-OCC pour l’offshore. ([hyosungheavyindustries.com][8])
### 3) Petite et moyenne échelle (décentralisé)
* **Enerwin Korea** : orientée petites/moyennes turbines, discours “faible vitesse de vent”, et références KS/technologie propriétaire dans ses documents. ([에너윈코리아(주)][10])
### 4) Chaîne d’approvisionnement coréenne (cruciale mais non-OEM)
* **CS WIND** : tours et sous-structures offshore. ([cswind.com][12])
* **Human Composites** : pales et composites; mentionné dans le programme de pales longues associé à Doosan. ([두산][13])
### 5) Points de vigilance (ingénierie + contrat)
* Exiger des preuves de **certification**, des hypothèses de charges adaptées (typhons, turbulence), une validation AEP indépendante, et un dispositif O&M (stocks, délais, logistique offshore) verrouillé contractuellement—c’est là que se jouent la bancabilité et la disponibilité. ([두산][2])

## English (EN)
### 1) What “wind turbine manufacturer” means in practice
In the wind industry, “turbine makers” usually refers to **OEMs that design and supply the full wind turbine generator (WTG)**—rotor/blades, hub, nacelle (generator, drivetrain), controls, and often commissioning plus long-term service. Separately, many companies are **major global suppliers of components** (towers, blades, foundations) without being full-turbine OEMs.
---
### 2) Korea’s main turbine OEMs (utility-scale / grid-connected)
#### A. Doosan Enerbility (두산에너빌리티) — Offshore-focused Korean OEM + nacelle assembly hub
* **Product line / positioning:** Doosan presents its on/offshore lineup (e.g., 3.3MW, 5.5MW, and an offshore 8MW class) and emphasizes designs optimized for **Korea’s relatively low wind speeds**. ([두산에너빌리티][1])
* **8MW offshore turbine certification:** Doosan’s 8MW offshore turbine (DS205-8MW class) obtained international certification (Type certification) around the end of 2022, as reported by Doosan and industry media. ([두산에너빌리티][1])
* **10MW offshore turbine (DS205-10MW) type certification:** Doosan announced that it received **type certification from UL** for its 10MW offshore model on **July 23, 2025**, describing this as the first Korean company to secure international certification for a 10MW offshore turbine. ([두산][2])
* **Korean offshore project track record:** Doosan states it has supplied offshore turbines to projects including **Jeju Tamra (30MW, 2017), Southwest Sea (60MW, 2019), and Jeju Hallim (100MW, 2025)**, and positions itself as having a leading domestic track record. ([두산에너빌리티][3])
* **Manufacturing ecosystem / localization push:** Doosan highlights increasing localization and strengthening the Korean offshore supply chain as part of its 10MW program. ([두산][2])
* **Nacelle assembly for global OEM turbines (local content pathway):** Under MoUs related to Equinor/Siemens Gamesa projects, nacelles of large-class turbines are planned to be assembled at Doosan’s **Changwon** facility. This is important because it creates an “industrial base” in Korea even when the turbine model is from a foreign OEM. ([equinor.co.kr][4])
**Practical implication:** Doosan is the clearest “Korean offshore turbine OEM” with publicly documented models and certifications, plus a parallel strategy to be a **Korean nacelle assembly platform** for very large turbines used in floating/offshore projects.
---
#### B. UNISON (유니슨) — Korean OEM expanding toward 10MW offshore
* **OEM identity:** Unison describes itself as a leading Korean wind power company providing solutions and wind farm experience. ([unison.co.kr][5])
* **10MW direct-drive offshore model announcement:** Trade press reports Unison unveiling a **10MW direct-drive offshore** model with a plan to move toward prototype and commercialization timelines. ([rechargenews.com][6])
* **Manufacturing partnership dynamics:** Industry coverage also notes Unison’s collaboration with Mingyang for manufacturing wind turbines in South Korea, reflecting how Korean OEMs may hybridize domestic manufacturing with foreign technology pathways. ([Offshore Wind][7])
**Practical implication:** Unison is a key domestic OEM name to track for offshore scale-up, but procurement requires close due diligence on **serial production readiness**, certification status, and service footprint for the specific model you intend to deploy.

#### C. Hyosung Heavy Industries (효성중공업) — Historically significant Korean turbine developer (status must be checked model-by-model)
* Hyosung states it developed Korea’s first 750kW turbine (2006), 2MW (2009), and installed a 5.5MW offshore turbine (2014) that received international certification from **DEWI-OCC** (2015). ([hyosungheavyindustries.com][8])
* Several industry directories list Hyosung among Korean manufacturers, but some global databases may label certain product lines as not active; this can reflect market reality (limited new sales) rather than corporate existence. ([thewindpower.net][9])
**Practical implication:** Hyosung matters for the history of Korean turbine development and certification. For new projects, confirm current commercial offerings, turbine platform availability, and long-term O&M capability.
---
### 3) Smaller / specialized Korean turbine makers (distributed, low-wind, hybrid use cases)
#### Enerwin Korea (에너윈코리아) — Small/medium “S-SAWT” wind turbines
* Enerwin positions itself around **small/medium wind turbines** with a distinctive blade design and claims performance at low wind speeds; it also references patents and certifications and mentions KS-related progress and public-sector designations in its materials. ([에너윈코리아(주)][10])
* This segment is typically relevant to **microgrids, islands, industrial sites, telecom power, and hybrid solar-wind**—not to GW-scale offshore arrays.
---
#### Global Wind Energy (GWE, 글로벌윈드에너지) — “WINDAWIND” branded large-scale onshore/offshore development/manufacturing claims
* GWE markets “WINDAWIND” as specialized in development/manufacturing/installation for large-scale onshore/offshore. ([gwe.kr][11])
* Treat such claims as a starting point; validate reference projects, serial production, and certification evidence.
---
### 4) Key Korean supply chain companies that are not turbine OEMs (but are critical)
#### A. Towers and offshore structures: CS WIND (씨에스윈드)
* CS WIND positions itself as a **global manufacturer of wind towers and offshore wind substructures**, headquartered in Korea. ([cswind.com][12])
**Why it matters:** Even if turbines are foreign OEM, towers/substructures can be heavily localized and drive local value-add and logistics feasibility.
#### B. Blades and composites: Human Composites (휴먼컴포지트) + testing ecosystem
* Doosan states its **100m blade** program involved Human Composites (blade manufacturer) with KIMS and testing at a certified facility, illustrating domestic capability in very large blades and structural validation. ([두산][13])
* Human Composites also positions itself as a wind blade-focused composite company. ([humancomposites.com][14])
#### C. Blade material inputs: Kumho P&B Chemicals / Toray Advanced Materials Korea
* Kumho P&B Chemical markets resin/chemical product lines tied to wind turbine blades. ([kpb.co.kr][15])
* Toray Advanced Materials Korea reported an MOU related to building an **offshore wind blade cluster**, reflecting broader domestic industrialization for blades/materials. ([torayamk.com][16])

## 5) How to evaluate Korean turbine OEMs (and avoid common failure modes)
Wind projects fail not only on LCOE, but on **bankability, certification, and service**. Use this checklist.
### A. Bankability and certification
* **Type Certification & Design Evaluation:** Confirm IEC 61400 alignment and the specific certifying body (e.g., UL as in Doosan’s DS205-10MW). ([두산][2])
* **Grid code compliance:** Korea’s grid connection requirements can be strict; verify power quality (LVRT/HVRT, reactive power, harmonics) with the utility/interconnection study.
### B. Korea-specific environmental engineering
* **Typhoon / turbulence / complex terrain:** Korea’s coastal/offshore sites can demand conservative load cases. Confirm extreme wind, wave, and lightning design assumptions; do not accept generic European North Sea settings without local validation.
* **Low-wind speed optimization:** Both Doosan and Enerwin explicitly emphasize low-wind performance narratives; translate that into measurable curves (power curve, AEP at site Weibull). ([두산에너빌리티][1])
### C. Service (O&M) and spare parts
* Evaluate: guaranteed response times, blade inspection strategy, gearbox/generator swap logistics, spares warehouse in Korea, SCADA access, and warranty exclusions.
* Offshore: confirm jack-up vessel strategy, weather windows, and major component exchange plan.
### D. Commercial risk controls
* Use staged contracting: **prototype / pilot array → serial order**, with performance warranties tied to independently verified AEP.
* Insist on clear liquidated damages (LDs): availability LDs, power curve LDs, and delay LDs.
---
## 6) Where Korean OEMs fit best today (pragmatic segmentation)
* **Utility-scale offshore in Korea (fixed + floating):** Doosan is the most documented domestic OEM pathway; Unison is the other key name to monitor. ([두산][2])
* **Local content strategy even with foreign turbines:** Nacelle assembly at Changwon is an example of how projects can localize manufacturing while using global OEM platforms. ([equinor.co.kr][4])
* **Distributed / low-wind niche:** Enerwin and other small wind specialists can be relevant where grid extension is expensive or hybrid systems are prioritized. ([Enerwin Korea Inc.][17])

## 한국어 (KO)
### 1) “터빈 제작업체”를 정확히 구분해야 하는 이유
풍력에서 “터빈 제작”은 보통 **WTG(풍력발전기) 완제품 OEM**(로터/블레이드, 허브, 나셀(발전기·구동계), 제어, 시운전·서비스)을 뜻합니다. 반면 **타워·블레이드·하부구조물**처럼 핵심 부품을 만들지만 완제품 OEM이 아닌 기업도 많아서, 발주/조달에서는 이 구분이 매우 중요합니다.
---
### 2) 한국의 대표 터빈 OEM(유틸리티급/계통연계)
#### A. 두산에너빌리티(Doosan Enerbility) — 국내 해상풍력 OEM의 “가장 명확한” 축 + 창원 나셀 조립 거점
* **라인업/포지셔닝:** 두산은 3.3MW, 5.5MW, 해상 8MW급 등 라인업을 제시하며, 한국의 **저풍속 환경 최적화**를 강조합니다. ([두산에너빌리티][1])
* **8MW급 국제인증:** 8MW급 해상풍력 터빈이 2022년경 국제인증(Type certification)을 받았다는 내용이 두산 자료/산업매체에서 확인됩니다. ([두산에너빌리티][1])
* **10MW(DS205-10MW) UL Type 인증:** 2025년 7월 23일, 두산은 **UL로부터 10MW 해상풍력 터빈 Type 인증**을 취득했다고 발표했습니다(국내 기업 최초 10MW급 국제인증이라는 서술 포함). ([두산][2])
* **국내 해상 프로젝트 공급 이력(두산 주장):** 제주 탐라(30MW, 2017), 서남해(60MW, 2019), 제주 한림(100MW, 2025) 등 공급 실적을 제시합니다. ([두산에너빌리티][3])
* **국산화/공급망 확대:** 10MW 프로그램과 연계해 국산화율 확대 및 국내 공급망 육성을 강조합니다. ([두산][2])
* **해외 OEM 대형 터빈의 ‘국내 나셀 조립’ 경로:** Equinor/Siemens Gamesa 관련 협력에서 **창원 공장에서 대형 터빈 나셀을 조립**하는 계획이 명시되어 있습니다. 이는 “한국 내 제조·고용·부품 생태계”를 만드는 핵심 장치입니다. ([equinor.co.kr][4])
**실무 포인트:** 두산은 “국내 OEM + 국제인증 + 국내 조립 거점”의 조합이 가장 분명합니다. 특히 해상(고정식/부유식)에서 국내 공급망을 묶는 역할이 강합니다.
---
#### B. 유니슨(UNISON) — 국내 OEM, 10MW 해상(직구동) 확장 시도
* **OEM 정체성:** 유니슨은 국내 풍력 선도 기업으로 솔루션/프로젝트 경험을 강조합니다. ([unison.co.kr][5])

* **제조 파트너십(기술·생산 결합):** Mingyang과의 국내 제조 협력 보도도 존재합니다(국내 생산과 해외 기술의 결합 모델). ([Offshore Wind][7])
**실무 포인트:** 유니슨은 국내 OEM 축의 핵심이지만, 프로젝트 발주 시에는 **양산 준비도, 인증·시험 단계, 장기 O&M 체계**를 “모델 단위로” 매우 촘촘히 확인해야 합니다.
---
#### C. 효성중공업(Hyosung Heavy Industries) — 국내 터빈 개발/인증 ‘역사’가 있는 기업(현재 판매/라인업은 별도 검증 필요)
* 효성은 2006년 750kW, 2009년 2MW 개발, 2014년 5.5MW 해상 터빈 설치, 2015년 **DEWI-OCC 국제인증**을 소개합니다. ([hyosungheavyindustries.com][8])
* 일부 글로벌 디렉토리에서는 “비활성” 표기가 보이기도 합니다(시장 상황상 신규 판매가 제한적일 수 있다는 의미로 해석될 여지). ([thewindpower.net][9])
**실무 포인트:** “지금 당장 신규 단지에 어떤 플랫폼을 얼마만큼 공급 가능한가”는 별개의 질문입니다. 최신 제품 라인업, 인증, 서비스 체계를 계약 전에 문서로 확정해야 합니다.
---
### 3) 소형/특수 목적(분산형·저풍속·하이브리드) 국내 업체
#### 에너윈코리아(Enerwin Korea) — 소형·중형 S-SAWT 계열
* 에너윈은 저풍속에서의 발전, 특허/인증, KS 관련 진행 및 공공 분야 지정 등 내용을 안내합니다. ([에너윈코리아(주)][10])
* 주 용도는 대규모 해상단지보다 **섬·마이크로그리드·산업부지·통신/비상전원·태양광+풍력 하이브리드** 쪽에 가깝습니다.
#### 글로벌윈드에너지(GWE) — WINDAWIND 브랜드(대형 온·해상 개발/제조/설치 표방)
* GWE는 WINDAWIND를 대형 온·해상 개발/제조/설치/판매로 소개합니다. ([gwe.kr][11])
* 레퍼런스 프로젝트, 양산/납품 이력, 인증 문서가 확보되어야 “실제 OEM”으로 평가 가능합니다.
---
### 4) “터빈 OEM은 아니지만” 한국에서 매우 중요한 공급망(부품/소재/구조물)
#### A. 타워·해상 하부구조물: 씨에스윈드(CS WIND)
* CS WIND는 **풍력 타워 및 해상풍력 구조물(하부구조 포함)** 글로벌 제조사임을 명시합니다. ([cswind.com][12])
#### B. 블레이드/복합소재: 휴먼컴포지트(Human Composites)

---
### 5) 발주/도입 시 실패를 줄이는 “실전 체크리스트”
1. **인증의 종류를 분해해서 확인**
* Type Certification(형식인증), Design Evaluation(설계평가), 부품 인증(블레이드, 제어, 타워 등)
* 예: 두산 DS205-10MW는 UL Type 인증 취득을 발표. ([두산][2])
2. **AEP(연간발전량) 검증 방식**
* 저풍속 최적화는 문구가 아니라, 사이트 Weibull/난류/전단 기준으로 AEP·가동률을 제3자가 검증해야 합니다. ([두산에너빌리티][1])
3. **해상 O&M 체계**
* 예비품 창고(국내), 주요부품 교체 리드타임, 선박/기상창(Weather window), 가동률 보증(Availability) LD 구조
4. **계통연계(Grid Code)**
* LVRT/HVRT, 무효전력, 하모닉 등은 EPC·계통연계 단계에서 가장 많이 문제를 일으키는 포인트입니다.
5. **계약 구조로 리스크를 고정**
* 파일럿 → 본단지(양산) 단계 계약
* 성능보증(파워커브)·가동률·납기 지연에 대한 LD를 문서화

## Français (FR)
### 1) Définition opérationnelle d’un “fabricant de turbine”
Dans l’éolien, un “fabricant de turbine” désigne généralement un **OEM** qui fournit l’aérogénérateur complet (rotor/pales, moyeu, nacelle, chaîne de conversion, contrôle, mise en service et service). Les fabricants de tours, pales ou fondations peuvent être essentiels sans être OEM de turbine complète.
### 2) Principaux acteurs coréens côté OEM (utilité / réseau)
* **Doosan Enerbility** : met en avant des machines adaptées aux conditions coréennes (notamment la performance en vents plus faibles) et a annoncé la **certification de type UL** pour sa turbine offshore **DS205-10MW** (23 juillet 2025). ([두산][2])
Par ailleurs, des accords industriels prévoient l’**assemblage local de nacelles à Changwon** pour de très grandes turbines offshore, ce qui structure une filière locale même lorsque la plateforme turbine est étrangère. ([equinor.co.kr][4])
* **UNISON** : la presse sectorielle rapporte la présentation d’un **modèle offshore 10 MW direct-drive**. ([rechargenews.com][6])
* **Hyosung Heavy Industries** : la société décrit ses développements historiques (750 kW, 2 MW, 5,5 MW offshore) et une certification DEWI-OCC pour l’offshore. ([hyosungheavyindustries.com][8])
