Assessment requirements

Modification History

Performance Evidence

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

• locates and applies relevant legislation, documentation, policies and procedures
• works effectively with others to undertake and complete well servicing nippling up and pressure testing that meets all of the required outcomes including:

• complying with written and verbal reporting requirements and procedures
• communicating clearly and concisely with others to receive and clarify work instructions
• communicating clearly and concisely with others to resolve coordination requirements throughout work activities

• demonstrates completion of participating in well servicing nippling-up and pressure test that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

• inspecting and adjusting equipment pressure ratings
• carrying out nippling up of Blowout Prevention (BOP)
• performing Blowout Prevention (BOP) and pressure testing
• carrying out rig-up to drill out operations
• processing written records and reports

Knowledge Evidence

The candidate must demonstrate knowledge of the following when participating in well servicing nippling-up and pressure testing:

• accessing, interpreting and applying the organisation and site requirements and procedures
• carrying out high pressure lines requiring pressure testing
• knowledge and use of test equipment
• testing equipment and procedures
• rig maintenance procedures
• identifying and managing surface production equipment
• well head identification – pressures
• well head identification – type (seal pockets, down hole gauges, stuffing boxes, DSA flanges)
• re-pressure testing
• manage and monitor nippling up and pressure testing within a team environment
• identifying well head pressure ratings
• pressure recording equipment operations
• PSV ratings and operations
• converting metric and imperial measurement
• performing gas testing
• performing a range of numerical calculations including:

• volume
• quantity
• mass
• weight
• length
• pressure
• using calculator if required
• using estimating skills (e.g. mental arithmetic, visualisation of size and quantity)
• basic geometry (e.g. interpreting depth, direction, angles)

Assessment Conditions

• An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,
• this unit is best assessed in the context of this sector’s work environment;
• where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills; and,
• this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,
• assessment may be conducted in conjunction with the assessment of other Units of Competency; and,
• assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,
• assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,
• where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,
• assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:

Industry sector	AQF** Level	Required assessor or Industry subject matter expert experience
Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction	1	1 Year
	2	2 Years
Drilling, Coal Mining and Extractive (Quarrying)	3-6	3 Years
Metalliferous Mining and Civil Construction	3-6	5 Years
Other sectors	Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation.

*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
