McDermott, together with its joint venture partner Chiyoda International Corporation (CIC), has substantially completed construction and commissioning of Train 1 of the Golden Pass LNG Project in Sabine Pass, Texas. Subsequently, Golden Pass LNG Terminal LLC led start-up operations and have achieved first LNG on Train 1, a landmark achievement in the delivery of one of North America's most significant LNG developments.

Reaching first LNG represents a major step forward in the project lifecycle, reflecting the culmination of years of engineering, procurement, construction and commissioning.

"This is a defining moment for the Golden Pass LNG Project and a significant achievement for McDermott, our partner Chiyoda and Golden Pass LNG," said Michael McKelvy, Chief Executive Officer and Chair of the Board for McDermott. "Reaching first LNG demonstrates the strength of our execution capabilities, the resilience of our teams and our ability to safely deliver complex LNG infrastructure that supports global energy needs."

McDermott serves as the lead partner of the joint venture responsible for the delivery of three LNG trains. Following first LNG on Train 1, McDermott and Chiyoda will continue to work on the Golden Pass LNG Project as construction and commissioning work on Trains 2 and 3 continues.
