OPITO Certified Initial and Refresher Control of Work Training for Performing Authorities

opito performing authority

Effective control of work is crucial to safe operations and the people responsible for control of work are central to it. By implementing consistent training standards for key personnel responsible for control of work at oil and gas installations and sites, many incidents caused by inadequate control of work (or where inadequate control of work is a contributory factor) may be mitigated or prevented.

 There are several responsible roles involved in the control of work, but one of the key roles is the person responsible for control of work at the worksite(s). The Initial and Refresher Training Programs for the Performing Authority specifies the generic skills, knowledge, understanding and behaviors required to carry out the role in a safe and effective manner.


The initial and refresher training will need to be supplemented by company and installation/site-specific training. This supplementary training will provide the Performing Authority with an understanding of the specific company and installation/site systems and procedures required for control of work, and details of the hazards and emergency response requirements associated with the Installation/Site.

The target group for Initial Training is personnel who intend to act, or are already acting, as a Performing Authority in the workplace. The target group for refresher training is designed to meet the refresher training and evaluation requirements for a performing authority.

  • Duration (Initial Training): 7 hours
  • Duration (Refresher Training): 4 hours
