HD Hyundai Heavy Industries Co., Ltd.

HD Hyundai Heavy Industries Co., Ltd. (KRX: 329180) is the world's largest shipbuilding and offshore heavy-industries entity, headquartered in Ulsan, South Korea. Founded in 1972, the company employs about 15,000 people in its core yard and manufacturing operations, delivered products to more than 51 countries, and recorded FY2025 revenue of KRW 17.58 trillion (about USD 13 billion). It is a subsidiary of the HD Hyundai group, itself a Fortune Global 500 company with annual revenue of about USD 49.7 billion. VerityRank Score: 89/100.

Business Overview

HD Hyundai Heavy Industries is the absolute manufacturing benchmark for ultra-large offshore assets. Its Ulsan shipyard contains 10 super-large dry docks and nine 1,600-tonne Goliath cranes, allowing simultaneous construction of several multi-billion-dollar FPSO hulls, floating production units and drillships. The company is an EPCIC turnkey builder: it performs steel fabrication, hull-block assembly, topsides integration and commissioning entirely in-house, and additionally dominates large marine and offshore platform engines with about 35% global share and cumulative production exceeding 200 million horsepower.

In December 2025 the group completed a strategic merger with HD Hyundai Mipo, reshaping its leadership across both offshore and merchant shipbuilding. The combination gives the group synchronous access to ultra-large and mid-size vessel segments, and 2026 second-quarter results showed operating profit surging 120.6% year-on-year to KRW 1.039 trillion, driven by high-value offshore projects such as the Trion floating production unit.

Growth Drivers

• The global deepwater and FPSO upcycle is the single largest demand driver; operators are ordering hulls and topsides years ahead of need.
• Group-wide engine leadership (about 35% share) secures margin-rich propulsion content on every major platform build.
• The HD Hyundai Mipo merger expands addressable market into mid-size LNG, containership and specialised tonnage.
• Korea's state-backed ship-financing and green-fuel retrofit programmes support order visibility into the late 2020s.

Challenges & Outlook

The principal challenges are external: steel-price volatility and currency swings directly hit heavy-asset margins, and Korea's acute shortage of skilled welders and outfitters combined with rising labour costs limits yard throughput. The company's enormous scale also makes it slower to pivot between product lines than smaller, more flexible competitors.

Outlook is favourable. Order books remain full of high-margin offshore and gas-carrying tonnage, and the group's engine franchise provides stable cash flow. Management expects the current offshore supercycle and post-merger synergies to sustain revenue growth and margin improvement through 2026-2027.

The Ulsan mega-yard itself is a strategic asset: ten super-large dry docks and nine Goliath cranes allow heavy blocks weighing thousands of tonnes to be handled in parallel, compressing hull cycles for FPSOs and floating production units that smaller yards cannot replicate. The company's engine division, with roughly 35 percent of the global large marine and offshore platform engine market and cumulative output beyond 200 million horsepower, secures in-house propulsion content on nearly every platform it builds — a margin shield in a steel-intensive business. For the Trion floating production unit and similar 2025-2026 high-value projects, HD Hyundai Heavy Industries has taken full responsibility for hull, topsides and commissioning, demonstrating the EPCIC turnkey capability that underpins its second-place standing in this ranking.
Looking to 2026-2027, the group is directing capacity toward gas-carrying tonnage and floating production assets, where order-book quality is highest, while the Mipo integration expands its reach into mid-size specialised vessels. This dual offensive — ultra-large floating production plus mid-size gas carriers — gives the group a breadth that no comparable yard complex currently matches.
