PMAOPS521C
Plan plant shutdown

This competency covers the planning of work to be done in a plant shutdown or outage, eg maintenance or inspection shutdown of a plant.

Application

In a typical scenario, a senior plant technician takes a lead technical role in the planning of a plant shutdown such as the maintenance/pressure vessel inspection shut. This competency requires the application of a detailed plant knowledge to the task of developing a detailed shutdown plan.

This competency is not actually about the shutting down of the plant itself (see PMAOPS411B Manage plant shutdown and restart), nor decommissioning (see PMASUP441C Decommission plant) but rather about the planning for the activities which will occur during a planned, major shutdown.

Shutdown planning is usually a team activity and so this technician would also be working with technical (process) experts, maintenance experts, contractor representatives and liaising with production and other management.

The reasons for the shutdown could include:

regulatory vessel inspection (PVI)

major maintenance

upgrades or refits

catalyst and/or column repacking

other activities which are scheduled for the shutdown.

Generally this would be a seconded role of a senior plant technician who for the period of the shutdown, and for a significant period before the shutdown, would undertake this as their primary activity.

Required Skills

This describes the essential skills and knowledge and their level, required for this unit.

Required skills

Competence includes the ability to:

identify all necessary sequences of activities to ensure safe and efficient shutdown

negotiate with a range of people to obtain the best outcome for the shutdown from the conflicting priorities

use planning tools to develop and modify complex plans/schedules

use planning tools to optimise the plans

use planning software (eg critical path, PERT or similar methods)

breakdown work tasks into steps/stages/trades/contractors/parts/designs/spares/tools

apply knowledge of plant operations, clearance/permits

logically sort work tasks into sequences

optimise planned activities into a workable schedule/plan

re-schedule/adjust/update plans during shutdown

estimate labour/job times/materials/interactions

follow plant schematics

apply process knowledge of plant

apply mechanical/electrical/instrument knowledge

Required knowledge

Competence includes an understanding of the operation of the plant and its units including:

principles of operation of entire plant being shut down

physics and chemistry relevant to the plant being shut down and the materials processed and their hazards/requirements

plant idiosyncrasies

all items on a schematic of the plant item and the function of each

correct methods of starting, stopping plant items

function of major components and their problems

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Assessment of this unit should include demonstrated competence on actual plant and equipment in a work environment. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

Typically this unit will be assessed by a shutdown planning project. It may not be appropriate to wait until the shutdown planning is completed as it may be desirable to test for competence before taking a major role in a shutdown. In this case a simulation should be used.

This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of 'what-if' scenarios both on the plant (during demonstration of normal operations and walk-throughs of abnormal operations) and off the plant.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Competence must be demonstrated in the ability to undertake a structured analysis of the activities to be completed during the shutdown and then undertaking the planning in a systematic manner.

Consistent performance should be demonstrated. In particular look to see that:

the plan minimizes the time of the shutdown

required activities/tasks are actively sought, broken into their components and scheduled

plant drawings (eg P&IDs) and engineering specifications are interpreted correctly

priorities for action consider all relevant factors.

This will typically be assessed by a major shutdown project on an operating plant. One complex project, or a number of simple projects, is required to demonstrate competence. As shutdown planning is usually a team activity, it is appropriate to assess the technician while they undertake this activity as part of the team, provided competence in all aspects can be demonstrated.

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

It may be appropriate to co-assess this unit with

PMASUP410B Develop plant documentation

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.


Range Statement

The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.

Codes of practice/ standards

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Context

This unit of competency includes all such items of equipment and unit operations which are covered by the shutdown. Where only a plant area is being shut (or one plant in an integrated complex), it also includes the impact of the shut on those areas still operating.

Databases may be:

electronic databases (such as Access, DB, Oracle)

other electronic forms (such as spread sheets)

card files

other paper based systems

Scheduling may include:

electronic project planning tools (such as MS Project)

other specialised planning software

paper techniques

Procedures

Procedures may be written, verbal, computer-based or in some other form. They include:

all work instructions

standard operating procedures

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant.

For the purposes of this Training Package, 'procedures' also includes good operating practice as may be defined by industry codes of practice (eg Responsible Care) and government regulations.

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
