PIPELINE ASSESSMENT TEMPLATE
Work Instructions
Topic specialists should use this template to record their assessment of the Pipeline aspects of a safety case, including the relevant details of the Pipeline
infrastructure; the identification of the Pipeline Safety and Environmental Critical elements and verification arrangements; confirmation that all pipeline hazards
from known initiators are identified and information on risk evaluation and management arrangements are provided and a summary of the Major Accident
Prevention document is included. Assessment should be against the requirements of SCR2015.
Exemplar Approach - This template should be used in accordance with the scope of the Assessment Instructions when the topic is included for assessment.
An exemplar approach may be sufficient if some material has been previously accepted and has not materially changed. For example a CMAPP or SEMS
from an existing, accepted safety case.
The template is one of a series covering all assessment topics, which together form a complete record of the safety case assessment and create evidence of
how the decision to accept the case, or not, was reached. The templates identify the specific regulatory requirements of SCR2015 for the topic and indicate
what the competent authority expects to find within a safety case to demonstrate that those requirements are met. The template complements the published
guidance that supports the regulations and topic sector guidance. The templates are available to promote transparency and assist duty holders in drafting
submissions.
Green text indicates regulatory requirements that are new in SCR2015.
Black text represents regulatory requirements that are contained in both SCR2005 and SCR2015.
Non Acceptance Issue - A Non Acceptance Issue (NAI) is a deficiency in the demonstration made within a safety case, which, if not resolved, will prevent the
case from being accepted under the relevant statutory provisions. Non Acceptance Issues must be sent by a formal letter from the IMT to the duty holder
requiring them to be dealt with in the appropriate manner, giving the duty holder a clear understanding of how to address the deficiency.
Clarification - A Clarification is an explanation provided by a duty holder on request during assessment to enable the assessing Inspectors to be confident of
their interpretation of the information in a safety case. Clarifications are a routine part of assessment work and should be raised with a duty holder promptly by
IMT or Topic Specialist where appropriate. Clarifications do not require formal letters. Communicating by telephone and email is sufficient. A meeting
between the duty holder and relevant topic specialists may also be appropriate in some circumstances for clarifications. Clarification is not a first stage before
raising non-acceptance issues. Any aspect that could credibly lead to a Non-Acceptance Issue should be raised as such in the first instance.
Design or Relocation Notification - Where the template is used to aid the inspection of a Design or Relocation Notification, Inspectors should consider if the
information provided meets the requirements of Schedule 5 of the regulations. The inspection must identify any Potential Non Acceptance Issues to draw to
the duty holder’s attention. Reference to these requirements outlined in Sections 2 of this template may be useful when forming an opinion. A record of the
inspection should be made in Section 2.

major accident risks will be controlled so as to ensure compliance with the relevant statutory provisions
Combined operations

Principle 28
The management system should address the additional risks associated with combined operations

Principle 29
A systematic approach should be taken to assessing the impact of combined operations on the conclusions of the operational safety case for
each installation.

Principle 30
A systematic approach should be taken to identifying and assessing any additional major accident hazards arising from combined operations.
These can be new hazards or changes to existing hazards.
Decommissioning and Dismantlement

Principle 33
When the safety case is revised to deal with decommissioning or dismantlement, the sequence of events should be described, from cessation of
production to dismantling of the structure

Principle 35

Chapter 2.3.2 Loss of Containment - Pipelines
The safety case should include an adequate description of all pipelines, including design parameters as necessary, and evaluate the impact of
pipelines and their inventories on the overall case for safety. It should include the identification of all pipeline hazards from initiators (e.g.
internal/external corrosion, erosion, fatigue, over pressure, third party damage), and the risk evaluation and management arrangements.
The safety case should also demonstrate that the Pipelines Safety Regulations (and other relevant statutory provisions) are complied with. By
including the summary of the Major Accident Prevention Document (prepared in accordance with the Pipelines Safety Regulations, Regulation 23)
for each relevant pipeline, the risk assessment in the safety case is interfaced with that for the pipelines.
