In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard has been developed for the surveying occupational area and is intended for persons who aim to achieve career advancement by gaining surveying skills leading to a qualification based on unit standards. A person who has successfully completed this unit standard is able to Pilot an Underwater Remotely Operated Crawler in any working environment.

A person credited with this unit standard is able to:
  • Launch the Crawler
  • Undertake Mining Operations with the Crawler
  • Make observations whilst mining
  • Surface and recover the Crawler
  • Monitor the instrumentation in the control room
  • Recover the Crawler in an Emergency 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    NQF Level 3 numeracy and literacy. The ability to Pilot an underwater Remotely Operated Vehicle will facilitate better understanding and proficiency in this unit standard.

    Recognition of prior learning
    Any learner wishing to be assessed may arrange to do so without having to attend additional education and training. The learner and assessor will decide jointly on the most appropriate assessment procedure
