Hyundai Heavy Industries Co., Ltd. (or HHI) is the world's largest shipbuilding company. Its headquarters are in Ulsan, South Korea. HHI was founded in 1972 by Chung Ju-yung as a division of the Hyundai Group, and in 1974, completed building its first ships.
In 2002, the company was spun-off from its parent company. HHI has four core business divisions: Shipbuilding, Offshore & Engineering, Industrial Plant & Engineering, and Engine & Machinery.
HHI also has five non-core related subsidiaries: Hyundai Electric & Energy Systems, Hyundai Construction Equipment, Hyundai Robotics, Hyundai Heavy Industries Green Energy, and Hyundai Global Service.
The Hyundai Group started as a small South Korean construction firm in 1947, headed by its founder, Korean entrepreneur Chung Ju-Yung. Another widely known and closely related Korean company, the Hyundai Motor Company, was founded in 1967, five years prior to the founding of the Heavy Industry Group. The motor company was also founded by Chung.
The name is an informal romanisation of the Korean 현대 (hyeondae) meaning "contemporary", which was Chung's vision for the group of companies that he founded.
