ExxonMobil Guyana Deploys Advanced Monitoring to Shield Subsea Gas Pipeline

GEORGETOWN, GUYANA — In a major move to safeguard the nation’s burgeoning energy infrastructure, ExxonMobil Guyana has announced the deployment of the Sentinel Proactive monitoring platform. This high-tech system is designed to provide real-time protection for the subsea pipeline corridor, a critical artery in Guyana’s landmark Gas-to-Energy (GtE) project.

The technology focuses on the shallow coastal waters where the risk of vessel anchoring—one of the leading global causes of subsea infrastructure damage—is most acute.

As maritime traffic intensifies along Guyana’s coast, ExxonMobil is utilizing Virtual Aids to Navigation (VAtoNs) to create a digital safety perimeter. Unlike physical buoys, these digital markers appear directly on ship navigation systems, allowing mariners to:

• Identify restricted zones earlier.

• Adjust courses before entering high-risk areas.

• Avoid accidental anchoring near sensitive subsea assets.

The system employs a multi-layered approach to communication. If a vessel enters a protected zone, the platform triggers escalating Automatic Identification System (AIS) safety messages. These alerts range from early “awareness” notifications to urgent “close-proximity” warnings, providing crews with immediate instructions to take corrective action.

The monitored pipeline connects the offshore Liza development in the Stabroek Block to the onshore facilities at Wales. This infrastructure is the backbone of a national strategy to slash domestic electricity costs by up to 50% through a new 300-megawatt power plant.

“Safeguarding what matters most requires both vigilance and innovation,” said Duncan Richards, Director at Sentinel Proactive. “Our deployment in Guyana enables crews to recognize risk earlier, respond faster, and operate with greater confidence.“

The 190-kilometer pipeline is currently in “preservation mode,” filled with dry nitrogen to prevent corrosion while the government completes the integrated power plant. Once operational, the system will ensure the continuous flow of natural gas under pressures exceeding 1,800 psi.

ExxonMobil Guyana, along with partners Hess and CNOOC, continues to scale its operations in the region. With the recent startup of the ONE GUYANA FPSO, production capacity in the Stabroek Block has already surpassed 900,000 barrels of oil per day, further cementing Guyana’s role as a global energy powerhouse.
