McDermott has received the International Organization for Standardization (ISO) 50001 certification for energy management of three of its flagship vessels: the Derrick Barge 32 (DB32), Derrick Barge 50 (DB50), and Derrick Lay Vessel 2000 (DLV2000). The certification process for all three vessels was completed in 2025, building on the successful certifications at four McDermott fabrication yards.

ISO 50001 provides a structured framework for organizations to improve energy performance through data-driven strategies and continuous improvement. Extending energy efficiency to its marine operations—from shallow-water to deepwater—demonstrates the company’s consistent approach to integrating sustainable energy practices across its global operations.

“Certification of these vessels creates measurable benefits for our customers and advances our Sustainability vision,” said Rachel Clingman, McDermott Executive Vice President, Chief Legal Officer. “It enhances our ability to support customer decarbonization goals and reinforces our role as a trusted partner in sustainable offshore execution.”

In connection with the certification, McDermott implemented a formal energy management system across DB32, DB50 and DLV2000 that aligns with the ISO 50001 “plan–do–check–act” framework. This included vessel-specific energy reviews, measurable performance baselines, and integration of real-time monitoring and reporting tools. Internal assurance teams conducted comprehensive audits, and a multistage, third-party audit confirmed ISO 50001 compliance.

“ISO 50001 certification for DB32 and DB50 reinforces our ability to deliver shallow-water projects with efficiency and predictability,” added Mike Sutherland, McDermott Senior Vice President, Offshore Middle East. “This achievement demonstrates how McDermott aligns operational excellence with our customers’ strategic objectives at a time when energy transition and energy and cost optimization are critical.”

“Deepwater developments are central to global energy security, and they demand solutions that balance performance with sustainability,” remarked Mahesh Swaminathan, McDermott Senior Vice President, Subsea and Floating Facilities. “The certification of DLV2000 under ISO 50001 reflects McDermott’s commitment to helping operators advance complex projects while reducing environmental impact.”
