Written Scheme of Examination

In order to conform with the requirements of the Pressure Systems Safety Regulations 2000, the user of an installed system shall not allow it to be operated without a Written Scheme of Examination (WSE) certified by a Competent Person.

A Written Scheme of Examination is not required for Portable or Mobile Systems.

The Written Scheme covers the following items as a minimum requirement:

  1. All protective devices (relief valves, burst discs).
  2. Manifold pressure regulators (only if they are a primary protective device)
  3. All High-pressure hoses and pigtails.
  4. All pipework where a failure would give rise to danger

As a competent body, GTP Ltd can draw up the Written Scheme of Examination documentation for the customer detailing:

• Safe operating parameters of the system
• Which parts should be examined
• The nature and frequency of examination required

I will also inform you immediately if your pressure system, or part of it, needs urgent attention.

If your existing gas system doesn’t have a Written Scheme of Examination, GTP Ltd can still audit your system – no matter how long it’s been in service, and issue the Written Scheme.  Your system may not even have an existing set of drawings, O&M manuals, or gas data sheets. GTP Ltd will be able to identify equipment types, manufacturers, part numbers, pipe sizes and types.
Contact me today to book a site survey of your pressure systems. The completed Written Scheme of Examination will typically be turned around within a week of the site survey.
