12th Annual Global STO & Maintenance Summit 2026

23–25 September 2026 | London, UK

The World’s Leading Platform for STO, Turnaround, Shutdown, Maintenance & Asset‑Integrity Leaders

The 12th Annual Global STO, Maintenance & Asset Integrity Summit, taking place from 23rd to 25th September 2026 in London, brings together senior executives, STO directors, maintenance leaders, asset‑integrity specialists, digital‑transformation experts, and key stakeholders from the global energy, petrochemical, utilities, industrial, and manufacturing sectors. As one of the most established and respected gatherings in the industry, the 2026 edition focuses on the rapidly evolving landscape of STO execution, digital maintenance, asset‑integrity strategies, and operational excellence—offering a strategic platform for high‑level dialogue, innovation, and best‑practice exchange.

Ultra Environment for Business Development & Strategic Partnerships

The London summit is designed to maximize business impact through curated networking sessions, private meetings, and targeted discussions.

With 200+ international participants and a dedicated exhibition zone, the summit provides a dynamic environment for technology demonstrations, solution showcases, and meaningful commercial engagement.

The best feature of the 2026 London edition is the AI–Digital Transformation & Innovation Challenge Day, designed to bring all participants and exhibitors together under one roof for a full day of collaborative problem‑solving. Through round‑table discussions, workshops, and interactive sessions, end users openly share their digital‑integration challenges, while solution providers demonstrate how their technologies address real STO, maintenance, and asset‑integrity needs.

Insightful Sessions Led by Industry Experts

The summit features a comprehensive program of keynote presentations, expert panels, and real‑world case studies delivered by industry leaders. Topics span digital transformation, risk mitigation, contractor management, predictive maintenance, asset‑integrity strategies, cost optimization, and the evolving future of STO execution in a digital‑first world. Each session is designed to provide actionable insights that participants can immediately apply within their organizations to enhance reliability, efficiency, and operational resilience.

Exclusive Networking With High‑Level Decision‑Makers

Networking remains a core strength of the summit. Designed as an intimate, high‑quality environment, the event ensures meaningful engagement by limiting participation and curating interactions with C‑suite executives, asset owners, STO directors, maintenance leaders, technology innovators, and solution providers. This structure enables deeper conversations, stronger relationship‑building, and genuine business‑development opportunities that are often difficult to achieve at large‑scale conferences. With industries accelerating investments in energy transition, industrial modernization, asset‑integrity upgrades, and digital transformation, the summit offers a unique window into upcoming opportunities and strategic priorities across global markets.

Leadership Workshops and Collaborative Group Work Sessions

The program also includes immersive leadership workshops and collaborative group sessions developed by the OPEX Advisory Board. These sessions focus on real‑world operational challenges, strategic decision‑making, and cross‑functional collaboration, enabling participants to sharpen their leadership capabilities through scenario‑based exercises, facilitated discussions, and peer‑to‑peer learning. This practical, hands‑on approach supports both individual development and organizational growth.
