Introduction

Background

The Corporate Management Framework is the highest level document in PDO’s Management System, and it applies to all PDO activities.It describes the framework that integrates all of PDO’s activities.The building blocks of the framework are:

Business Direction / Business Results
Business Management / Review and Appraisal

1 Introduction

1.1 Background

Operations Variance and Change Control encompasses a suite of procedures designed to address and manage variances and change management carried out by Production Operations. The suite of procedures comprises:

· Facilities Change Proposal (PR-1001a)

· Trip/Alarm/SCADA Settings Change (PR-1001b)

· Temporary Override of Safeguarding Systems (PR-1001c)

· Operations Procedure Temporary Variance (PR-1001e)

The suite of procedures listed is stand-alone and address the varying requirements of Operations. The procedures provide a structured approach required for the safe and effective implementation of any required changes.

The decision to introduce any change, be it procedural or to plant and process systems shall only be made after due consideration of the consequences, review of the technical, commercial or safety aspects, and shall always be formally approved by the authorised person prior to execution or implementation.

1.2 Purpose

The purpose of this procedure is to provide Operations personnel with a ‘high level’ procedure for executing changes within the Operations environment. Attention shall be drawn to areas of the procedure that are considered mandatory.

1.3 Distribution / Target Audience

This procedure targets and should be distributed and brought to the attention of the Operations and Engineering staff.

All supervisory staff shall be responsible for ensuring that this procedure is strictly adhered to, and thoroughly understood by their team members.

1.4 Structure of this Document

2 Operations Variance and Change Management Procedure

2.1 Scope

The Operations Variance and Change Management process shall be used to define the nature of the variance / change and to identify the specific process that shall be implemented to manage that variance / change.

For clarity the processes are covered under separate procedures.

PR-1001a - Facilities Change Proposal (previously SI-18)

Requests for permanent changes to process plant & operating practices must be made using the Facility Change Proposal (FCP) procedure.

PR-1001b - Trip and Alarm Setting Change (previously SI-13 and SI-23)

Requests for changes to process alarms & trips must be made using the appropriate form approved by Production Coordinator and authorised by the relevant specialist CFDH.

PR-1001c - Temporary Override of Instrument Safeguarding Systems (previously SI-25)

These are temporary changes, which must be applied for via the appropriate forms, approved by the Production Coordinator and authorised by the relevant specialist CFDH.

PR-1001d - Integrated Production Plan Variance (previously SI-14)

Withdrawn

PR-1001e - Operations Procedure Temporary Variance (previously SI-14)

An “Operations Procedure Temporary Variance” shall be initiated when an intended activity cannot be effectively or safely performed within the existing Operations ‘envelopes’ or a Production Operations Procedure. The requested variance shall be approved by the Delivery team Leader and authorised by the Asset Manager.

NOTE: Authorisation to allow a variance from an established and documented Well Services Procedure is NOT covered in this document. This rests with the CDFP for Well Services and shall be formally obtained prior to implementing a variance within their respective procedures.

2.2 General Points to Consider

a) / The proposed change including supporting documentation shall be forwarded to the ‘discipline / line supervisor’[1] for screening. The discipline / line supervisor shall decide whether the proposal is realistic and if all required documentation to support the request has been supplied.
b) / Rejected proposals shall be returned to the originator. Screened and accepted proposals shall be forwarded for endorsement
c) / In all cases where a change to an established system or procedure is required, a correctly completed proposal shall be submitted by the originator for approval and authorisation by line management.
d) / Where ever possible, the originator should attach supporting documents / drawings or sketches to the respective proposal.
c) / It is mandatory that the correct line authority approves all change request forms. If technical specialist authorisation is required, this must also be obtained from the CFDH before implementation.
d) / All change requests shall be initially reviewed by the Production Coordinator and then screened by the Delivery Team Leader where, appropriate, who will either accept or reject the proposed variance / change.
e) / When a change to a system or procedure take place, the nature of the change shall be disseminated to the relevant Operation personnel by the Production Coordinator.
f) / The Production Coordinator shall check on the status of change requests and monitor their status / validity /progress on a monthly basis.
g) / Individual discipline supervisors shall keep a log of change requests and copies of the proposals on site. This shall be auditable

2.3 Operations Variance and Change Management Process

1. / The proposal for a Variance or Change should be reviewed by the Line Supervisor or the Production Coordinator who shall advise the ‘originator’ on the correct procedure to follow.
2. / If the proposal required a change to a system, equipment, plant design, operating envelope etc, then it shall be considered as a ‘facilities change’ and be actioned in accordance with PR-1001a. Management of the change proposal shall be undertaken by the Field Change Proposal team.
If the proposed Variance or Change does not meet the criteria it should be rejected or redefined.
3. / If the proposal requires that the setpoint of trip, alarm or SCADA instrumentation be changed then it shall be actioned in accordance with PR-1001b. Management of the change proposal shall be undertaken by the discipline supervisor and the functional support group.
4 / If the proposal requires a temporary variance for the overriding of Safeguarding Systems then it shall be actioned in accordance with PR-1001c. Management of the variance shall be undertaken by the discipline supervisor and reviewed by process and discipline engineers.
5. / If the proposal is a request for a variance to a Mandatory Controlled Procedure then it shall be actioned in accordance with PR-1001c. Management of the variance shall be undertaken by the Production Coordinator and must be authorised by the Asset Manager.
6. / If the proposed variance or change is not addressed by any of the above then it does not require to be covered under this procedure.
