How We Can Help You
Shift Scheduling
Design and implement compliant 24/7 controller schedules that reduce fatigue risk, align with PHMSA and API RP-755 standards, and maintain coverage without overburdening staff.
Fatigue Risk Management
Build and strengthen fatigue risk management systems that integrate PHMSA CRM and API RP-755 compliance requirements - combining policy, training, and alertness monitoring to improve safety and operational readiness.
Workload Assessment
Conduct data-driven, PHMSA-compliant workload assessments that objectively measure controller task demands, identify fatigue and cognitive overload risks, and provide actionable recommendations to improve reliability and compliance readiness.
Staffing and Workload Optimization
Identify optimal staffing levels and workload balance to ensure controllers have sufficient time to monitor, analyze, and react - in line with PHMSA 195.446(e)(5) workload requirements.
Employee Training
Deliver targeted training programs that help controllers and supervisors recognize fatigue, manage alertness, and meet PHMSA Control Room Management expectations.
