Scope of application for verification

This specification may be adopted for the verification of parts of process facilities or selected project phases.

Process facilities typically comprise the following systems:

- process safety functions

- pressure relieving devices

- blowdown and flare system

- HIPPS system

- utility systems

- piping

- pressure vessels (not covered by this OSS)

- passive fire protection

- active fire protection

- HVAC systems

- fire and gas detection systems

- shutdown systems

- process equipment

- hazardous area classification.

which are applied in various configurations and tailored to each particular project's specific requirements.

This specification describes the principles of a levelled verification involvement. These principles may be applied both for planning of any need or obligations for independent external verification (third party) as well as internal company verification (second party).
