POSCO Engineering & Construction

POSCO Engineering & Construction (POSCO E&C) is the engineering and construction arm of the South Korean steelmaker POSCO. The company provides engineering, procurement, and construction (EPC) services for industrial facilities. Its project portfolio includes steel mills, petrochemical complexes, power generation plants, and infrastructure works. POSCO E&C delivers turnkey solutions that cover feasibility studies, detailed design, procurement, construction, commissioning, and handover.

The firm’s headquarters is located in Vietnam, as stated in the organisational context. This location serves as the central point for its management and coordination activities. The headquarters in Vietnam houses the company’s executive and administrative offices. From this base, POSCO E&C directs its project execution and support functions.

POSCO E&C is distinguished by its specialization in heavy industrial EPC, particularly for steel and petrochemical plants. Its close integration with POSCO’s steel production expertise enables it to offer technically robust solutions for metallurgical facilities. The company has a track record of executing large‑scale, complex projects that require meticulous coordination of multidisciplinary teams. In March 2023, POSCO E&C experienced a data leak that exposed infrastructure and piping schematics, employee information, business registration documents, and contract agreements. The leak was publicly disclosed by the threat actor Kernelware on BreachForums, who released the data without ransom demands. This incident highlighted the handling of sensitive project data by the firm and underscored the cybersecurity challenges faced by industrial EPC contractors.

POSCO Engineering & Construction is a wholly owned subsidiary of POSCO, forming part of the broader POSCO corporate group. As a subsidiary, it benefits from the parent company’s financial backing, technological resources, and global network. The organisational structure aligns its EPC capabilities with POSCO’s vertical integration strategy in the steel and related industries. Headquartered in Vietnam, the company operates under the governance and strategic direction of its South Korean parent.
