ATEX & KCs Certified Explosion-Proof Phones for South Korea’s Refining, Petrochemical & Shipbuilding Industries

South Korea is one of Asia’s largest refining and petrochemical hubs, with combined refining capacity over 3.4 million bpd concentrated in Ulsan, Yeosu, Daesan, Onsan, and Incheon. Major operators — SK Energy, GS Caltex, S-Oil, HD Hyundai Oilbank, Lotte Chemical, LG Chem, Hanwha Solutions, Hanwha TotalEnergies, Kumho Petrochemical, and Korea Petroleum Industries — run Zone 1 / Zone 21 classified process units across crude distillation, FCC, hydrocracking, aromatics, olefins, and polymer manufacturing.

Equipment used in South Korea’s explosive atmospheres must comply with KCs (Korea Certification of Safety) marking under the Occupational Safety and Health Act, administered by KOSHA (Korea Occupational Safety and Health Agency). The KCs Ex scheme references KS C IEC 60079 standards, harmonised with . Imported equipment can route via CoC for KCs cross-acceptance, while ATEX certification supports EU-origin equipment and EPC projects of multinational scope.

Korean shipbuilding — HD Hyundai Heavy Industries (Ulsan), Samsung Heavy Industries (Geoje), and Hanwha Ocean (formerly Daewoo Shipbuilding, Geoje) — constructs the world’s majority of LNG carriers, FPSOs, FLNGs, and offshore drilling units. These yards require certified intrinsically safe communication devices for hazardous-area testing zones, commissioning teams, and topsides integration.

Major industrial estates — Ulsan Mipo & Onsan, Yeosu National Industrial Complex, Daesan Petrochemical Complex, and the Incheon LNG terminal — operate hundreds of Zone 1 / Zone 21 process areas. EPC and turnaround contractors require ATEX / KCs compliant communication tools for shutdown maintenance, inspection, and shift coordination.
