Remove components from mechanical plant equipment
URN: COGPEM38
Business Sectors (Suites): Process Engineering Maintenance
Developed by: Cogent
Approved on:
27 Mar 2018
Overview
This standard is about your competence in removing components from mechanical equipment using manufacturers' procedures. You will be required to ensure suitable precautions are taken to prevent the escape of liquids or gases. Following removal, the components should be labelled and stored according to organisational procedures. You will be following your organisation's safe working practices and working within the work permit procedures.
This standard deals with the following:
1 Remove components from mechanical plant equipment
During this work you must take account of the relevant worksite operational requirements, procedures and safe working practices AS THEY APPLY TO YOU.
Performance criteria
You must be able to:
P1 work safely at all times, complying with health and safety and other relevant regulations and guidelines
P2 establish, and where appropriate, mark component orientation for re-assembly
P3 ensure that any stored energy or substances are released safely and correctly
P4 remove the required components using approved tools and techniques
P5 take suitable precautions to prevent damage to components, tools and equipment during removal
P6 check the condition of the removed components and record those that will require replacing
P7 label and store the removed components in an appropriate location
P8 store or discard the removed components in accordance with approved procedures
P9 maintain documentation in accordance with organisational requirements
Knowledge and Understanding
You need to know and understand:
K1 you must have a working knowledge and understanding of what your responsibilities are in respect of Health, Safety and Environment. This should include the limits of your personal responsibility, your legal responsibility for your own health and safety and the health and safety of others
K2 you must have a working knowledge of the relevant regulations and the safe working practices and procedures required within your work area
K3 you must have a working knowledge and understanding of the engineering drawings and related specifications to which you will be expected to work, including technical drawings (component, assembly, general arrangements, isometrics, 1st and 3rd angle projections), method statements, product worksheets and tolerances
K4 you must have a working knowledge and understanding of component removal methods and techniques including what the types of isolations and connections are that have to be made, and which tools, equipment and methods can be used to remove specific components from specific plant and equipment
K5 you must have a working knowledge and understanding of the identification of component defects that have been removed
K6 you must have a working knowledge and understanding of the labelling and storage of components for re-use and what the available marking systems are for specific components and connections
K7 you must have a working knowledge and understanding of the disposal of unwanted components and substances; this should include what substances could be released during the removal of components, which risks are associated with the release of substances, and where to access information on the environmental standards, including an appreciation on COSHH, SEPA and company procedures
K8 you must have a working knowledge and understanding of the tool and equipment care and control procedures including what your responsibilities are for ensuring the security of tools and equipment that you use
K9 you must have a working knowledge and understanding of your responsibilities with regard to the reporting lines and procedures in your working environment
Scope/range
Scope Performance
1 The level and extent of responsibility will involve you being responsible for ensuring the equipment and work site is safe for others or yourself to work in by following defined procedures. You will be accountable for the integrity of the work site and ensuring the work is recorded in a formal manner. Authorisation for proceeding with the work will be given by authorised signatories within the PTW system
2 The equipment to be worked on may be robust or fragile. Robust components are those that are resistant to most forms of damage or disruption during their working lives. Fragile components are those that are easily disrupted or damaged. Damage or disruption could be due to physical, chemical other forces (e.g. Electro-magnetic). Typical equipment could be:
2.1 Heat exchangers
2.2 Pumps
2.3 Engines
2.4 Components of process systems
3 The type of components to be removed. Typical components could be:
3.1 Components of mechanical/hydraulic/pneumatic systems
3.2 Mechanical metering devices
3.3 Components of engines
3.4 Safety limit protection devices
3.5 Actuators
3.6 Components of pumps
4 The removal techniques or procedures to be followed should involve components to be removed that may require a sequential series of steps to complete the removal. The components may be difficult to access and may be surrounded by other fragile/valued components and may need specialised tooling requirements. Removal may involve more than one differing technologies and/or involve a significant number of fragile components.
The specifications to which a candidate would be expected to work to could include:
4.1 Percussion
4.2 Pressure/hydraulic
4.3 Mechanical strip
4.4 Thermal techniques
4.5 Manual handling
4.6 LOLER
5 The removal operations may be simple or complex. Simple removal/replacement of components refers to situations where the component is quickly and easily removed from/replaced in its position. Typical examples could include:
5.1 Undoing threaded fasteners to release the component
Complex removal/replacement refers to situations where components can only be removed or replaced by dismantling the surrounding areas e.g. by cutting and/or where removal/replacement of one component necessitates removal/replacement other interacting components.
