PTSC Corporation/PTSC Thanh Hoa successfully organizes STG#3 MRT & Performance Testing Workshop

On September 24, 2026, PTSC Corporation organized the STG#3 MRT (Mechanical Run Test) & Performance Testing Workshop as part of the STG#3 EPC Replacement Project at the Nghi Son Refinery and Petrochemical Plant (NSRP), Thanh Hoa. The workshop was attended by representatives from the STG#3 Project Management Board of PTSC Corporation, PTSC Thanh Hoa, NSRP, and relevant technical experts, engineers, and project management teams.

Representatives of NSRP, PTSC Corporation, and PTSC Thanh Hoa attend the Workshop.

To date, the Project has completed 5 out of 8 major milestones, including procurement of the 41.4 MW Steam Turbine Generator (STG), dismantling inspection and assessment, engineering, procurement of major equipment, and installation of auxiliary systems. The Project has reached 85% overall progress and achieved approximately 360,000 safe work hours without any lost-time incident.

By the end of November 2026, the STG package is expected to be transported from Japan to NSRP. The project will then proceed with installation, alignment, connection, pre-commissioning, Mechanical Run Test (MRT), no-load testing, and the 72-hour Performance Test before final acceptance and handover to NSRP, which is planned for April 2027.

The installation, pre-commissioning, MRT, and Performance Test are critical final stages of the Project. The workshop therefore provided an opportunity for technical experts, operations teams, and project management personnel to discuss the execution plan, identify potential risks, and agree on suitable control measures. It also strengthened coordination among NSRP, PTSC, PTSC Thanh Hoa, and the Original Equipment Manufacturer (OEM) to ensure safe and effective project execution.

Mr. Nguyen Ba Tuan – Deputy Director of PTSC Thanh Hoa and STG#3 Project Manager – delivers the opening remarks.

One of the main topics discussed at the workshop was the execution plan for the Live-Steam MRT at NSRP. Carrying out the MRT under actual steam conditions and using the refinery’s existing auxiliary systems requires careful preparation and close coordination. With the participation of OEM specialists, PTSC and NSRP teams discussed and aligned on the approach based on actual site conditions.

At the workshop, Mr. Nguy Nhu Lap – Manager of Maritime Vessels – O&M Department and STG#3 Site Manager – presented the key contents of the project, including Project Overview, Overall Installation Sequence, Commissioning & MRT, Performance Testing, and Grid Synchronization. The presentation provided an overall view of the work sequence from installation completion testing and operation of the STG unit.

Mr. Nguyen Ngoc Anh – STG#3 Project Coordinator – presented “Commissioning Management Approach,” covering four key areas: Communication Management, Risk Management, System Completeness, and Start-up Readiness. The presentation focused on effective coordination during commissioning and the importance of identifying risks and confirming all required conditions before start-up.

Mr. Le Anh Vu – Operations Section Manager Section 5 – presented the operating plan and Plant Stabilization Plan for the Performance Test, with a focus on maintaining the steam and power balance. This preparation is important to ensure safe and stable STG3 operation during testing while maintaining the stability of the refinery’s existing systems.

Mr. Le Anh Vu – Operation Section Manager – presents at the workshop.

Through the technical discussions, NSRP, PTSC/PTSC Thanh Hoa, and relevant parties reviewed key technical requirements, shared practical experience, and agreed on the coordination approach for the next project phase. The workshop helped strengthen preparation for the MRT and Performance Test and create a common understanding of the work sequence, responsibilities, and key requirements before STG#3 enters the testing and operation stage.

With the common goals of Safety – Quality – Schedule, PTSC Corporation and PTSC Thanh Hoa will continue to apply their technical capability and project experience while working closely with NSRP and other partners. These preparations will provide a strong foundation for the successful installation, commissioning, testing, and stable operation of STG#3.
