2.5.3 Requirement fora New Design Safety Case For a material change to a Production Safety Case, anew Design Safety Case will be required to be submitted before the revised Production Safety Case, unless explicitly exempted by the CER. Such exemptions will be in limited circumstances, where the risk implications are relatively low. The new Design Safety Case will only need to cover parts of the designated petroleum activity that are affected by the material change. It is not a document that is maintained over the lifetime of the installation and is only concerned with the proposed material change. Fora material change to a Non-production Safety Case, only a revised Non-production Safety Case is required.
