HD Hyundai Heavy Industries Co., Ltd.
Ulsan South Korea • Hyundai Heavy Industries (HHI)
Under Group of:
Hyundai Heavy Industries (HHI) is located at Ulsan. It accounts for over 15% of the entire DWT of vessels produced worldwide each year, making it the largest single shipbuilder in the world. Its enormous facility is located about one hour north of Busan.
Design facilities
HHI has invested heavily in R&D over the last 20 years. Each process including future-proof technologies carried out by HHI and KSOE (Korea Shipbuilding and Offshore Engineering, HHI Group's holding company), such as ship and ocean hydrodynamics, machinery and propeller design, has its own R&D division. These centres have extensive facilities including a 210m towing tank, a circulating water
channel and a cavitation tunnel. HHI also has a structural testing rig, which is used to determine the strength and fatigue characteristics of large, complex ship structures.
Construction facilities
HHI’s massive facility covers over 7m sq m and embraces nearly every process required to build a ship. Ten dry-docks lie within its perimeter, including Number Three Dock with a capacity of 1m DWT. The large number of dry-docks means a wide variety of ship types and sizes can be accommodated. HHI’s capacity is currently estimated to be 85–100 vessels per year, though this will increase due
to the development of new techniques for building vessels on land. In addition to the shipbuilding facilities, HHI has a large engine works, building all the engines fitted to HHI ships. As well as forging crank and propeller shafts, the company has extensive propeller manufacturing capabilities.
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.
