What DSEC does
DSEC (주식회사 디섹 / DSEC Co., Ltd.) is a privately held B2B shipbuilding and marine engineering services firm founded in 1993 and headquartered in Busan, South Korea. The company operates from three South Korean facilities (head office in Jung-gu Busan, a Quality Center in Geoje-si, and a logistics center at Busan New Port) and serves shipyards, commercial shipping companies, and naval/government clients across North America, Europe, the Middle East, and East Asia. DSEC positions itself as a "Total Ship & Marine Technology Provider," delivering integrated service packages rather than discrete products.
The company's core offerings span six service lines: engineering design (marketing, basic, detail, and production design supported by 3D modeling), material procurement and supply (supported by proprietary E-SCM and DCPS digital platforms), LNGC cargo containment system (CCS) repair, erection, and GTT-certified training, shipyard development and operation consulting, eco retrofit solutions (LNG fuel systems, SOx scrubbers, BWMS), and logistics services. Notable technical differentiation includes GTT certification for LNG membrane containment systems, a world-first achievement in LNG-fueled containership design, and a GTT-certified CCS Training Center producing qualified welders and bonders for global dispatch. Documented track records include 193 newbuilding LNGC leak tests, 111 in-service LNGC CCS projects, and 23 vessels co-built with General Dynamics NASSCO since 2006.
DSEC generates revenue through project-based, multi-year enterprise contracts negotiated directly with shipyard and shipping company decision-makers. Pricing is quote-driven and not publicly disclosed, with services bundled into integrated total-solution packages. Major customers include General Dynamics NASSCO, Samsung Heavy Industries, Matson, TOTE, Tsakos, Hamburg Sud, Maran Tanker, Hoegh Autoliners, Zodiac, Capital, SK Shipping, HMM, Navantia, Shell, and PONANT. The company has no subsidiaries, no disclosed funding rounds, no public listing, and CEO Yoon Seok-yong (윤석용) and Chairman Park Il-dong (박일동) lead the organization.
