Superheat Heat Treatment

Superheat Plays a Critical Path Role in Irving Oil’s Operation Osprey Turnaround

Superheat is proud to have played a critical path role in Operation Osprey, one of the largest turnaround investments in Irving Oil’s history at its Saint John, NB, refinery.

Representing a $235-million investment, the 75-day turnaround brought together approximately 2,100 additional skilled workers from more than 55 contracting companies to execute critical infrastructure replacements, equipment upgrades, and maintenance, supporting the continued safe and reliable operation of Canada’s largest refinery.

Throughout the turnaround, Superheat supported heat treatment activities across multiple units, completing approximately 185+ welds over seven weeks, including several large and complex PWHT applications. Our Field-Level Execution Team, SmartPoint™, SmartPak™, and SmartCenter™ technologies all played a key role in project execution, combining advanced field-level equipment with remote operation and monitoring to support consistent, controlled heat treatment throughout the turnaround.

We’re proud of our team’s contribution and grateful for the opportunity to work alongside Irving Oil and the many skilled trades who came together to deliver Operation Osprey.
