Alcad Batteries Provide Reliable Backup Power for Unmanned Offshore Well Head Platform in Vietnam’s Su Tu Den Oil Field

Alcad Vantex nickel technology batteries are delivering reliable backup power for UPS (uninterruptible power supply) systems that support critical control and safety functions on the Well Head Platform A (WHP-A) unmanned offshore oil platform operated by Cuu Long Joint Operating Company (CLJOC) in Vietnam’s Su Tu Den oil field.

Previously, CLJOC had only used VRLA batteries with its UPS systems, but made the switch to Alcad after being convinced of the reliability, maintenance-free and long-life benefits of nickel technology.

12AlcadCLJOCVietnam is the third-largest oil producer in Southeast Asia and is a net exporter of crude oil. The Su Tu Den (Northeast Black Lion) oil field is located within offshore Block 15-1, approximately 150 km offshore from Vietnam, which has an estimated recoverable volume of 621 million barrels of crude oil.

CLJOC is a partnership between state-owned PetroVietnam, the main shareholder, ConocoPhillips, Korea National Oil Corp, SK Corp and Geopetrol. PetroVietnam has been producing Su Tu Den crude from the Cuu Basin since 2003.

Alcad has provided CLJOC with 100 Vantex VTX1 M 270 nickel-based cells, with a rated capacity of 270 Ah – enough to support 90 minutes of autonomous backup power for the offshore platform’s control and safety systems – along with design, commissioning and testing services.

Alcad’s latest generation Vantex batteries are designed to achieve the total reliability and optimized Total Cost of Ownership (TCO) essential for equipment deployed in remote locations. Compared with lead‐acid batteries, the Vantex nickel‐based battery chemistry offers an exceptionally long and predictable service life of up to 20 years, even in the demanding environment experienced in oil and gas operations, with no risk of ‘sudden‐death’ failure. The Vantex cells are completely maintenance‐free, with no requirement for routine topping‐up with water. They are also easy to handle and install while their capability for fast charging further reduces potential downtime.
