Korea Shipbuilding & Offshore Engineering is the integrated holding company that consolidates Hyundai Heavy Industries, Hyundai Mipo Dockyard, and Hyundai Samho Heavy Industries, enabling cross-yard coordination for large offshore plant and rig packages.
In 2021 the group joined a joint venture with Singapore's Keppel to bid on offshore projects, securing a combined pipeline of roughly 2.5 trillion won in offshore construction work, including floating platforms and fixed-structure plants.
For 2026, KSOE's offshore strategy emphasizes modular fabrication of topsides modules and integrated project management, positioning it as a preferred EPC partner for NOCs that want a single point of contact for rig and platform construction.
Daewoo Shipbuilding & Marine Engineering (DSME)
Daewoo Shipbuilding & Marine Engineering (now part of Hanwha Ocean) has historically focused on high-spec semi-submersible rigs and floating production storage and offloading (FPSO) units, with a portfolio of more than 20 offshore rigs delivered since 2005.
DSME's Geoje shipyard is equipped with a 60,000-ton floating drydock and heavy-lift cranes capable of handling 14,000-ton modules, allowing it to execute large deepwater drilling units and complex spar-type platforms.
Recent 2025-2026 contracts include a fifth-generation semi-submersible for a Gulf of Mexico operator and a mid-water FPSO for a Middle Eastern NOC, both scheduled for delivery in 2027 under lump-sum, turnkey agreements.
Samkang M&T and DH Global: Specialized offshore yards
Samkang M&T is a medium-sized offshore module yard based in Ulsan that specializes in pre-fabricating topsides, jacket legs, and substructures for both fixed and floating platforms.
In 2022-2024 Samkang executed over 15 topside packages for Korean and foreign EPC contractors, with an average project value of 80-150 billion won and a 95 percent on-time delivery rate, which has helped it win repeat work from global majors.
DH Global operates as a tier-two fabricator focusing on integrated modules, piping spools, and steel structures for offshore platforms, often subcontracted by DSME or KSOE for high-pressure, high-corrosion environments.
Project types and technical capabilities
Korean offshore construction companies today build a full spectrum of rigs and platforms: jack-up rigs, semi-submersibles, drillships, floating production units (FPU), FPSOs, and fixed-structure platforms.
From 2020 to 2025, Korean yards delivered approximately 18-22 offshore rigs annually, with about 60 percent being jack-ups and 30 percent semi-submersibles or FPSO-type units, reflecting continued demand for exploration and marginal-field development in Asia and Latin America.
Many of these offshore units are built to international standards such as API, ISO 19901, and DNV rules, and increasingly incorporate digital twin systems and remote monitoring packages for onboard safety and predictive maintenance.
Typical Korean yard offerings
- Self-elevating jack-up rigs for shallow-to-mid-water drilling (up to 120 meters).
- Semi-submersible drilling rigs capable of 1,200-2,000 meter water depths.
- Floating production units (FPU) and FPSOs for marginal fields.
- Fixed jacket platforms accompanying subsea tie-backs.
- Integrated topsides modules for topside skidding or installation.
Market context and economic impact
The Korean offshore construction sector contributed roughly 7-9 percent of the country's total shipbuilding and marine engineering revenue in 2025, with offshore rig and platform work valued at about 1.1-1.4 trillion won per year.
In 2021, the 850 billion won platform order from Petrobras alone represented roughly 1.3 percent of that year's total Korean shipbuilding and offshore export revenue, highlighting how single large offshore contracts can materially move the needle for domestic yards.
By 2026, Korean firms are increasingly targeting NOCs in Indonesia, Vietnam, Brazil, and Mexico, where national content rules and local yard partnerships favor Korean offshore contracting consortia over pure European or Chinese competitors.
Key differentiators of Korean rig builders
One of the main competitive advantages of Korean rig builders is their integrated supply chain, which combines in-house steel fabrication, heavy-lift logistics, and advanced welding and NDT (non-destructive testing) capabilities within a single yard or group.
For example, Hyundai Heavy Industries reports that its average construction cycle for a 400-foot jack-up rig is about 30-36 months from order to delivery, with module accuracy within ±5 mm on major deck beams and 99.2 percent weld-rework rate below 0.8 percent.
Many Korean yards also maintain long-term agreements with European equipment vendors such as Kongsberg, Aker Solutions, and NOV, giving them access to standardized drilling packages and automation systems that shorten integration timelines.

How to evaluate a Korean rig contractor
When selecting a Korean offshore rig firm, buyers typically scrutinize backlog, safety record, modularization capability, and integration experience with international equipment vendors.
In 2024, an informal survey of 15 international drilling contractors rated Korean yards at an average 4.2/5 on delivery reliability and 3.9/5 on commercial flexibility, suggesting that while schedules are strong, contract terms can be relatively inflexible compared to European yards.
Many operators now require Korean contractors to provide full digital twin models and 3D constructability reviews before final steel cutting, which has reduced field rework by roughly 20-30 percent according to post-project audits.
