FSO PTSC Lac Da Vang Sets Sail for Vietnam’s Offshore Oil Project

Overview of the Vessel

A floating storage and offloading (FSO) unit, the FSO PTSC Lac Da Vang (FSO PTSC LDV), has recently departed from Tongzhou Bay in Nantong, Jiangsu, to embark on its mission at the Lac Da Vang project, located in Block 15-1/05 off the coast of Vietnam. This journey marks a significant milestone in the project’s development and highlights the collaboration between several industry leaders.

Collaborative Efforts

Singapore-based OceanSTAR Elite Group led the construction of the FSO in partnership with Promor, an oil and gas engineering solutions provider. The transportation arrangements were managed by the client, PetroVietnam Technical Services Corporation (PTSC). This collaborative effort has been pivotal in navigating the complexities of offshore oil projects.

The contract granted to PTSC Asia Pacific, a partnership between Yinson Production and PTSC, underscores the growing synergy among various stakeholders in this venture. The FSO’s sail-away occurred just a month after its official naming ceremony on June 23, 2026, a moment celebrated by the team involved.

A Testament to Engineering Excellence

Promor’s commentary on the vessel’s departure is telling:

“Seeing the FSO PTSC LDV depart is a rewarding reminder that successful offshore projects are built on months of engineering, meticulous planning, quality fabrication, and outstanding teamwork.”

This sentiment reflects the extensive groundwork involved in bringing the FSO PTSC LDV to life, showcasing the dedication and expertise of numerous professionals across different disciplines.

Construction Timeline and Milestones

Construction of the FSO kicked off in February 2025, and over a span of 16 months, the project achieved key milestones including:

• First Steel Cutting – An important initial step marking the project’s commencement.
• Keel Laying & Hull Construction – Critical stages in turning design into reality.
• Major Lifting Operations – Essential for assembling the vessel components.
• Vessel Launching – A pivotal moment bringing the FSO to the water.
• System Commissioning – Ensuring all operational systems meet safety and functionality standards.

OceanSTAR Elite Group emphasized that the project achieved over 1.6 million safe working hours without a single lost-time incident, a remarkable accomplishment in the challenging realm of offshore construction.

Safe Collaboration

The successful delivery of the FSO PTSC LDV relied heavily on the trust and collaboration among multiple partners, including:

• Murphy Cuu Long Bac Oil Co., Ltd. (MCB)
• American Bureau of Shipping (ABS)
• Titan Wind Offshore

Together, they sustained a robust execution process that started with the first steel cut and seamlessly transitioned to quayside delivery.

Operational Features and Strategic Importance

The FSO features a substantial storage capacity of 460,000 barrels, designed to bolster operational efficiency and support sustainable offshore oilfield operations. The Lac Da Vang field, where it is headed, is projected to yield an estimated ultimate recovery of 100 million barrels of oil equivalent (mmboe), with anticipated peak production reaching 30 to 40 mboepd (gross) and 10–15 mboepd (net).

Murphy Oil operates Block 15-1/05 within the Cuu Long Basin, holding a 40% working interest, while partners PetroVietnam Exploration Production and SK Earthon maintain 35% and 25% stakes, respectively. This collaborative approach ensures a comprehensive strategy for maximizing both operational efficiency and resource recovery in the region.

Conclusion

The departure of the FSO PTSC Lac Da Vang from its construction site is more than just a logistical move; it symbolizes the culmination of meticulous planning, engineering excellence, and collaborative synergy among industry leaders. As the unit makes its way to Vietnam’s offshore oil field, it stands as a testament to the capabilities and innovations driving today’s offshore energy sector.
