Hanwha Ocean Co., Ltd.
Seoul South Korea • Hanwha Ocean (HWO)
Under Group of:
Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME) was founded in 1978 on a greenfield site in Okpo, on Geoje Island, South Korea. DSME was taken by the Hanwha group in 2023. Today, Hanwha Ocean (HWO) is recognised as one of the three largest shipbuilders in the world.
Design facilities
HWO’s research, basic design, and marketing offices are based in Seoul, supported by the in-house advanced technology and production teams in Okpo. The company also operates a robotics technology centre in Siheung. HWO conducts extensive R&D activities, including computational Fluid Dynamics (CFD) for hull optimisation, fatigue analysis, wind tunnel testing for funnel design and aerodynamics.
Construction facilities
The main HWO yard in Okpo spans over 4 million square metres and has the capacity to deliver more than 60 ships annually. Number One Dock (1 million m³) is used for building VLCCs, Suezmax tankers, and LNG carriers. Number Two Dock specialises in large containerships, with several floating docks supporting additional production needs. In recent years, HWO constructs ships on land and skids them onto barges, which are then carefully submerged for launch.The company also operates subsidiary block fabrication facilities in China, supporting large-scale ship construction.
Independent shipyard insight, future-ready newbuild guidance and expert advisory support to help you make confident new construction decisions from planning to delivery.
New construction decisions shape the performance, compliance and commercial value of a vessel for decades. Lloyd’s Register helps owners, operators, charterers and project teams make those decisions with greater clarity, combining trusted classification expertise with practical newbuild advisory support.
Through LR’s New Construction Guide, clients can access independent shipyard intelligence across North Asia, including China, Korea and Japan. The guide helps compare shipyard capabilities, facilities, track record, vessel specialisms and future-fuel readiness, supporting smarter shipyard selection and earlier project planning.
Beyond the guide, LR provides advisory support across the full newbuild lifecycle. From technical specification development and design review to regulatory impact assessments, alternative fuel studies, energy efficiency, carbon capture readiness, site support and operational preparation, LR helps clients reduce uncertainty before it becomes a cost, a delay, or a risk.
With global technical authority, local shipyard knowledge and deep maritime expertise, Lloyd’s Register supports future-ready vessels from the earliest concept through to construction and delivery, helping clients build with confidence in an increasingly complex market.
