Application
This unit describes the skills and knowledge required to perform well servicing nippling-up and pressure testing in drilling. It prepares individuals to carry out nippling-up of blow out prevention (BOP), perform BOP and pressure testing, and carry out rig-up to drill out operations.
It applies to those working in supervisory or technical specialist 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.
Licensing, legislative and certification requirements that may apply to this unit can vary between states, territories, and industry sectors. Users must check requirements with relevant body before applying the unit.

2. Perform nippling-up | 2.1 Identify manufacturer and site requirement for selected blow out prevention system 2.2 Supervise or participate in connecting BOP to casing 2.3 Supervise or participate in nippling-up of BOP |
3. Perform pressure test | 3.1 Perform accurate BOP test 3.2 Carry out rig-up to drill-out operations according to parameters, specifications and operations 3.3 Carry out pressure tests prior to operations and record in writing test results |
Evidence of Performance

Assessment Conditions
Mandatory conditions for assessment of this unit are stipulated below. The assessment must:
include access to:
personal protective equipment
equipment required to participate in well servicing nippling-up and pressure test
be conducted in a safe environment; and,
be assessed in the context of this sector's work environment; and,
be assessed in compliance with relevant legislation/regulation and using policies, procedures and processes directly related to the industry sector for which it is being assessed; and,
confirm consistent performance can be applied in a range of relevant workplace circumstances.
Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated work 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.
Assessor requirements
Assessors must be able to clearly demonstrate current and relevant industry knowledge and experience to satisfy the mandatory regulatory standards as set out in the Standards for Registered Training Organisations 2015/Australian Quality Training Framework mandatory requirements for assessors current at the time of assessment and any relevant licensing and certification requirements. This includes:
vocational competencies at least to the level being delivered and assessed
current industry skills directly relevant to the training and assessment being provided
current knowledge and skills in vocational training and learning that informs their training and assessment
formal relevant qualifications in training and assessment
having knowledge of and/or experience using the latest techniques and processes
possessing the required level of RII training product knowledge
having an understanding and knowledge of legislation and regulations relevant to the industry and to employment and workplaces
demonstrating the performance evidence, and knowledge evidence outlined in this unit of competency, and
the minimum years of current** work experience after competency has been obtained as specified below in an industry sector relevant to the outcomes of the unit.
It is also acceptable for the appropriately qualified assessor to work with an industry expert to conduct assessment together and for the industry expert to be involved in the assessment judgement. The industry expert must have current industry skills directly relevant to the training and assessment being provided. This means the industry subject matter expert must demonstrate skills and knowledge from the minimum years of current work experience after competency has been obtained as specified below, including time spent in roles related to the unit being assessed:
Industry sector | AQF indicator level*** | Required assessor or industry subject matter expert experience |
Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Infrastructure | 1 | 1 year |
2 | 2 years | |
Drilling, Coal Mining, Extractive (Quarrying), Metalliferous Mining and Civil Infrastructure | 3-6 | 3 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. |
*Guidance on simulated environments has been stipulated in the RII Companion Volume Implementation Guide located on VETNet.
**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 a minimum number of site assessments as determined by the relevant industry sector, across various locations.
*** While a unit of competency does not have an AQF level, where a unit is being delivered outside of a qualification the first numeric character in the unit code should be considered as the AQF indicator level for assessment purposes.
