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 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.

Why it matters

Extending energy efficiency to its marine operations – from shallow-water to deepwater – demonstrates McDermott's consistent approach to integrating sustainable energy practices across its global operations. The certification enhances the company's ability to support customer decarbonization goals and reinforces its role as a trusted partner in sustainable offshore execution.

The details

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.

  • The certification process for all three vessels was completed in 2025.
