McDermott announces the launch of a Circularity Calculator, aligned to ISO 59020 standards, to support growing demand for transparent circular economy performance measurement across the lifecycle of energy infrastructure projects.

Developed in-house, the tool provides a standardized, data-driven method for assessing circularity from design through to decommissioning. The new tool is part of McDermott's strategy to embed circularity principles across all phases of project execution, with the following benefits:

• ISO 59020 alignment: Independently assured to meet international standards for circularity measurement.
• Lifecycle insights: Quantifies the recyclability or reuse potential of a design.
• Measurement and reporting: Provides quantifiable data as a basis for decision making in material selection.

"Circularity strategies drive cost, environmental, and supply chain benefits for our projects, operations, and customers," said Rachel Clingman, McDermott's Executive Vice President, Sustainability and Governance and Chief Legal Officer. "Our Circularity Calculator provides traceable data aligned with global standards to support strategic decisions and appropriate reporting."

Initially deployed across McDermott's decommissioning portfolio, the calculator quantifies circularity based on data collected after processing materials through recycling, reuse, and other disposal pathways.

"This tool provides the transparency and data needed to integrate circular resource strategies into subsea and offshore energy infrastructure projects – essential elements to enhancing not only project sustainability, but also operational efficiency and value for our customers," said Mahesh Swaminathan, McDermott's Senior Vice President, Subsea and Floating Facilities.
