We want to highlight the crew of O’Connor Boilermakers who completed a successful hydrostatic test this week on a major boiler retube project. The project consisted of over 220 tube welds, as well as rolling over 350 tubes in the steam drum and mud drum. It is thanks to crews like this that O’Connor is able to deliver a quality product to our clients in a timely manner.
