PVS: PTSC M&C Ships 16,000-Tonne Offshore Substations to Poland's Baltica 2

Overview

PTSC Mechanical & Construction (PTSC M&C), a subsidiary of Petrovietnam and the operating arm behind listed ticker PVS on HNX, has completed and shipped four offshore substation (OSS) topsides and four module support frames for Poland’s Baltica 2 offshore wind farm. The eight steel structures total 16,000 tonnes and represent Vietnam’s first export of offshore wind structures to Europe. The milestone matters for PVS because it positions the contractor inside the European offshore wind supply chain rather than only the domestic oil and gas segment.

Key Facts

• Baltica 2 carries an estimated investment of about PLN 30 billion, or more than USD 7.8 billion, developed by PGE and Orsted.
• PTSC M&C fabricated and exported four OSS topsides plus four module support frames, weighing 16,000 tonnes in total.
• Each substation has 375 MW of capacity, weighs roughly 3,500 tonnes and stands five storeys tall; each module support frame weighs 500 tonnes.
• The four substations passed more than 720 operational tests before shipment.
• Loading and transport at the PTSC M&C yard in Vung Tau took 43 days and nights.
• Baltica 2 will comprise 107 wind turbines and four offshore substations, with total capacity of about 1.5 GW.
• The project sits roughly 40 km off the Polish coast in the Baltic Sea.

What Happened

Polish renewable energy portal Gramwzielone reported on 18 September that the four OSS topsides and four module support frames had left Vietnam and were en route to Poland after loading and transport were completed at PTSC M&C’s Vung Tau yard. The structures are described as the “energy heart” of Baltica 2, collecting power from the project’s 107 turbines and transmitting it safely and stably to Poland’s national grid. Each substation is a five-storey, 375 MW unit weighing about 3,500 tonnes.

The article states that the four substations passed more than 720 operational tests, confirming that their complex electrical systems are ready to operate reliably in the harsh marine environment of the Baltic Sea. Loading and shipping took 43 days and nights, keeping construction of one of the Baltic’s largest offshore wind projects on schedule. For PTSC M&C specifically, the report frames this as the first time an offshore wind project executed by a Vietnamese company has been exported to Europe, a step toward strengthening its position in the global offshore wind supply chain.

Market Context

PVS closed at VND 33,300 on 21 September 2026 on HNX, where it trades under the Petrovietnam technical services complex. The stock sits in the oil and gas services sector, a segment that has historically tracked crude prices and domestic upstream capex rather than European renewable construction cycles. This contract is therefore a diversification signal: it ties PVS’s order book to offshore wind fabrication demand in the Baltic, a market where European developers are scaling capacity but face constrained local yard availability.

Strategic Significance

The strategic thesis is that PTSC M&C can convert Vietnamese fabrication cost advantages and Petrovietnam’s marine engineering base into recurring European offshore wind work. Baltica 2 is a reference project with a named developer group, PGE and Orsted, and a defined technical scope, which matters more for future bidding than the revenue from this single package. If European developers treat the Vung Tau yard as a qualified supplier of OSS topsides, PVS gains a demand stream less correlated with domestic oil and gas cycles. The main competitive question is whether Vietnamese yards can hold schedule and quality against established European and Asian fabricators on larger, repeat orders.

What to Watch

• Confirmation of installation and commissioning of the four OSS units at the Baltica 2 site in the Baltic Sea.
• Any new PTSC M&C contract awards from European offshore wind developers, disclosed via PVS filings or Petrovietnam announcements.
• PVS quarterly disclosures on backlog composition and the share of revenue from offshore wind versus oil and gas services.
• Baltica 2 progress milestones from PGE and Orsted, including turbine installation and grid connection timelines.
• HNX foreign-ownership and block-trade data for PVS as the export narrative reaches international investors.
