17MANAGEMENT OF CHANGE


All PDO Operations HSE Cases shall be reviewed on an annual basis (by year end) to ensure that all the following sections of the HSE Case remain true and valid to operations.

It is the responsibility of the Delivery Team Leader as the HSE Case Custodian to ensure these updates are completed, with support from the HSE Case administrator.

Bow-tie assessment

Have any new severity 5 or high level risks been identified?

Are all barriers still valid?

Have any new barriers been identified?

Are all barriers correctly categorised (Inherent Safety, SCE, Critical Activity)?

SCE listing

Is the hardware barrier correctly identified as an SCE?

Does the barrier have the correct SCE identifier attached?

Are all the performance standards complete and up to date?

Has all SCE been entered into the Asset Register?

Has the task information embedded within the system been added to the HSE Critical Task information?

HSE Critical Tasks

Has there been any Directorate/Departmental re-organisation?

Are all the reference indicators and positions still current?

Have all personnel signed off to say they are aware of their tasks (annual requirement) and that their assigned tasks are correct?

Remedial Actions

Are any of the remedial actions overdue?

Do any of these open action items compromise safe operations of the plant as signed in the Statement of Fitness?

Statement of Fitness

Annual review of the Statement of Fitness to ensure that it is correct and accurately reflects the status of operations.

The Statement of Fitness shall be signed off by the HSE Case Custodian after each review.

Other changes that may trigger a revision to the Operations HSE Case are listed below:

As part of a Material Change to the Facility, operation or surrounding environment that may have a potential impact on the risk profile

When it cannot be verified that the performance of safety critical elements (SCEs) meet the performance standards and/or when mitigation measures have been employed for extended periods to compensate for this shortfall

Prior to any material changes to the organisational arrangements or personnel levels

Following a major incident involving the Facility or operation, or from lateral learning from other major incidents applicable to the Facility or operation

Enhancements in knowledge or technology that change the basic assumptions on which the risk tolerability and ALARP demonstrations are based

Updated HEMP study findings/results

If there is a change to any of the signatory parties for the HSE Case, i.e. HSE Case Owner (Director), HSE Case Custodian (Delivery Team Leader) or HSE Case Administrator (Technical Safety Engineer)

All identified changes to the HSE Case, whether as a result of a periodic review or any of the other criteria listed above shall be assessed by the HSE Custodian, the Technical Safety Engineer and the HSE Case administrator (where this is not the TSE). Where relevant, the change should also be assessed by a discipline Technical Authority.
