“Recruiting and retention of key resources are vital for EPC companies to avoid outrunning workforce capacity. For us, it is about making sure the projects are safe and well run in order to maximize the employee experience. Innovation—such as modularization or off-site fabrication—can help meet the demand. But, it is key to provide training before and during the onboarding experience so our new folks can add value from day one.” - Michael E. McKelvy, McDermott President & Chief Executive Officer, during the EPC Keynote Panel at the Energy Projects Conference & Exhibition
