What Offshore Energy Installation does

Offshore Energy Installation JSC (OEI) is a Vietnam-based private joint stock company founded in 2020, headquartered in Ho Chi Minh City with a fabrication yard and operations base in Vung Tau. The company provides offshore engineering, procurement, construction, and installation (EPCI) services to the renewable energy and oil & gas industries, with a portfolio of eight service lines: offshore transportation and installation of heavy equipment up to 10,000 tonnes; marine fleet operation and maintenance; skilled personnel and technical support; steel structure fabrication; EPCI project management; operations and maintenance; provision of marine equipment and certified operators; and removal and decommissioning. OEI serves offshore wind developers (Orsted, CIP, Van Oord, Vestas, PECC2, REE Corporation, Me Kong Wind Power), offshore installation contractors (MMA Offshore, Seaway 7, Sing Da Marine Structure), and oil & gas clients (Chevron Thailand, Vietsovpetro). Geographically, the company is actively operating across Vietnam, Taiwan, Thailand, and Indonesia.

OEI's technology stack combines conventional structural and wind engineering software (SACS, ANSYS, PLAXIS 3D, WindPRO, WAsP, NREL-OpenFAST, NREL-FAST.Farm) with owned marine assets including the OEI-03 cable laying barge, OEI-Tan Cang 01 transportation barge, and OEI-Tancang-03 work barge, plus a state-of-the-art fabrication facility in Vung Tau. The company holds a patent for SEASTAR, a proprietary offshore wind farm design. Equipment is endorsed by Bureau Veritas and ABS, and operators are certified to GWO and OPITO international standards.

OEI's business model is project-based B2B services, with revenue generated through custom-quoted EPCI contracts, equipment and operator rentals, marine logistics, and managed services. There is no public pricing, no recurring SaaS revenue, and no disclosed external funding. Go-to-market is direct enterprise sales combined with industry association memberships (VOEG, NOF, BritCham Vietnam, GWEC) and strategic alliances with Herera (heavy lift) and Sapura (offshore installation), enabling OEI to bid on scopes beyond its owned asset base. The leadership team includes Founder and Construction Manager Dao Binh.

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Boskalis: Dutch global offshore services and dredging major with growing offshore wind installation fleet; competes for cable lay and subsea protection scopes that OEI also services, particularly in Taiwan and SE Asia.
• Seatrium (formerly Keppel Shipyard / Sembcorp Marine): Singapore-based offshore rig, FPSO, and offshore wind foundation constructor; competes in jacket fabrication and offshore wind substructure engineering at a much larger scale than OEI.
• Van Oord: Dutch marine contractor executing offshore wind EPCI globally; an OEI customer (cable burial, pontoon services) and a strategic benchmark for full-scope offshore wind installation capability.
• Jan De Nul Group: Belgian offshore contractor with cable lay, foundation installation, and heavy-lift vessels active across Asia-Pacific offshore wind; comparable in scope to OEI's EPCI ambitions but at materially greater scale.

Regional players

• MISC Berhad: Malaysian maritime and offshore floating solutions operator; competes in offshore vessel support and heavy-lift transportation across SE Asia, comparable to OEI's barge-based installation model.
• Sapura Energy: Malaysian integrated offshore services and energy company with installation, subsea, and offshore wind capability across SE Asia; an existing strategic alliance partner of OEI for offshore installation, and a regional benchmark for offshore EPCI scale.
• Swire Pacific Offshore: Hong Kong-based offshore support vessel operator across SE Asia and Australia; competes in marine transportation, anchor handling, and offshore installation vessel services relevant to OEI's fleet.

Direct peers

• Alpha ECC: Vietnam-based engineering and construction company with offshore project execution; already a strategic implementation partner of OEI and a comparable size/scope competitor for Vietnamese offshore and subsea scopes.
• Vietsovpetro: Vietnam-Russia joint venture operating offshore platforms in the Cuu Long and Nam Con Son basins; offers offshore installation, subsea, and decommissioning services that directly overlap with OEI's O&G service lines.
• PTSC (PetroVietnam Technical Services Corporation): Vietnamese offshore EPCI, marine transportation, and O&M services provider to the regional O&G and offshore wind sectors. OEI already lists PTSC MC as a strategic implementation partner; both compete and collaborate on similar offshore scopes in Vietnamese waters.
