The correct installation of process control equipment - field and control room, is essential to achieve:
- minimum commissioning time;
- minimisation of safety risks;
- good on-stream factor;
- minimisation of 'life time' costs.
In addition to these benefits correct installation is an essential requirement to ensuring all EX equipment is installed to EN 60079 -14 and its certification requirements.
Where Instrumented Safety Functions are being applied to meet the identified Risk Reduction then it is imperative that such functions are fully in conformance with the design installation requirements.
The most economical and systematic method of achieving the above is to use a quality assurance check list. Such list will monitor that the installation requirements for each type of equipment are achieved and where a non-conformance is identified it is corrected early in the installation programme. This will avoid costly modifications and delays if only an 'end of construction' quality audit is done.
