WELL ENGINEERING & OPERATIONS DESIGN & RELOCATION NOTIFICATION INSPECTION TEMPLATE PRODUCTION INSTALLATION
AND
WELL ENGINEERING & OPERATIONS DESIGN NOTIFICATION NON-PRODUCTION INSTALLATION TO BE CONVERTED
INSPECTION TEMPLATE
Work Instructions
Topic specialists should use this template to record their inspection of the Well Engineering and Operations aspects of a design or relocation notification, and
of a design notification for a non-production installation to be converted to a production installation. Inspection should be against the requirements of
SCR2015.
Exemplar Approach - This template should be used in accordance with the scope of the Inspection Instructions when the topic is included for inspection. An
exemplar approach may be sufficient if some material has been previously inspected and has not materially changed.
The template is one of a series covering all inspection topics, which together form a complete record of the design or relocation inspection and create
evidence of the inspection of the notification. The templates identify the specific regulatory requirements of SCR2015 for the topic and indicate what the
competent authority expects to find within a notification 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.
Potential 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. During the inspection of the design or relocation notification, the inspector must
identify any potential Non Acceptance Issues to draw to the attention of the duty holder.

Relevant Pre-Existing Guidance
 APOSC Principles:

Principle 1
The factual information should meet the SCR2015 requirements and provide sufficient detail to support the arguments made in the case
Management of health and safety

Principle 2
The safety case should demonstrate that the management system is adequate to ensure compliance with the relevant statutory provisions
Major accident risk evaluation

Principle 13
In deciding what is reasonably practicable, the case should show how relevant good practice and judgement based on sound engineering,
management and human factors principles have been taken into account
Major accident risk management

Principle 16
The safety case should explain how inherently safer design concepts have been applied in the design decisions taken

Principle 17
The measures for preventing major accident hazards should take account of the various activities undertaken during the installation’s current
phase of operation
Design

Principle 26
A design notification should describe how the principles of risk evaluation and risk management are being applied to the design to ensure that
major accident risks will be controlled so as to ensure compliance with the relevant statutory provisions

Principle 27
Well engineering aspects, especially those that refer to well operations before the start of facility operations, should be included in the design
notification
