Description
This unit describes the skills and knowledge required to assess well control equipment and report and record faults, carry out well kill operations and conduct housekeeping activities. It applies to those working in supervisory roles. They generally perform tasks involving a broad range of varied activities most of which are complex and non-routine and are responsible for the quantity and quality of the output of others.No licensing, legislation or certification requirements apply to this unit at the time of publication.
