Ultimate Work Authority Requirements

Ultimate Work Authority (UWA) means the authority assigned to an individual on the facility to make the final or ultimate decision to stop work or take action taking into account all applicable regulations.

The UWA is in charge of the activity at all times.

Responsibility: The SEMS program should clearly define who is in charge at all times.

  • The SEMS program should have a process to identify the individual with the UWA on the facility. You should designate this individual taking into account all applicable USCG regulations that deal with designating a person in charge of an OCS facility.
  • In the event that multiple facilities, including a mobile offshore drilling unit (MODU), are attached and working together or in close proximity to one another to perform an OCS operation, the SEMS program should identify the individual with the UWA over the entire operation, including all facilities.
  • You should ensure that all personnel clearly know who has UWA and who is in charge of a specific operation or activity at all times, including when that responsibility shifts to a different individual.

Emergency Procedures The SEMS program should provide that if an emergency occurs that creates an imminent risk or danger to the health or safety of an individual, the public, or to the environment, the individual with the UWA is authorized to pursue the most effective action necessary in that individual's judgment for mitigating and abating the conditions or practices causing the emergency.
