PTSC Offshore Services - POS

What PTSC Offshore Services - POS does

PTSC Offshore Services Joint Stock Company (POS), established September 28, 2007, as a spin-off from PTSC (Petrovietnam Technical Services Corporation), is a Vietnamese publicly-listed B2B services contractor focused on offshore oil and gas and — more recently — renewable energy infrastructure. The company operates from its Vung Tau headquarters at the PTSC Downstream Port and delivers three integrated service lines: Marine Construction (offshore hook-up, commissioning, and brownfield modification), Operations & Maintenance (long-term manpower supply, daily/turnaround maintenance, fabrication and scaffolding for offshore platforms and petrochemical complexes), and Industrial Construction (fabrication and installation for refineries, petrochemical plants, thermal power, and offshore wind components), supplemented by a barge rental operation.

The company owns strategic marine capital — POS-01 (a 300-berth accommodation crane work barge with a 300mt HUISMAN deck crane) and PTSC-01 (a 5,000-ton flat-top barge) — that supports large-scale offshore mobilization. POS holds ISO 9001, ISO 14001, ISO 45001, and ISO 3834-2 certifications and has accumulated 200+ completed projects, 17 years of operating history, 40 million manhours LTI-free, and repeated HSE recognition from clients including NOC (Qatar), KNOC, Rosneft, BP, PVEP, and QatarEnergy.

Revenue is generated primarily through project-based professional services contracts won via competitive tendering, with an enterprise field-sales motion targeting international and domestic oil & gas operators, petrochemical/refinery owners, and offshore wind developers. The customer base spans ~30 entities across Vietnam, Qatar, Saudi Arabia, Australia, Thailand, Myanmar, UAE, and Brunei. Notable clients include JVPC (since 2005), KNOC (since 2007), Lamprell Saudi Arabia (CRPO), NOC/Hanwha Ocean/SEMBCORP (Gallaf), Subsea 7/Santos (Barossa), Technip FMC/Idemitsu/PTSC (Sao Vang Dai Nguyet), Long Son Petrochemicals (Package A1), Ørsted (Greater Changhua CHW2204), PV Gas, and Chevron Thailand. Pricing is custom project-quoted with no public rate cards. FY2021 revenue was 2,099.29 billion VND (achieved 144% of plan); the 2026 AGM has set a 3,500 billion VND revenue target alongside articulated international expansion and EPC-contractor ambitions.
