Key Focus Areas

Sep 2012 – Rev-02

Key Focus Areas

• HSE Management:

PDO‟s Health, Safety, and Environment Management System (HSE MS) is a structured approach to achieving our HSE goals, objectives, and targets, and managing the HSE risks associated with our business.

Page 17: Presentation for MEED - Copy

Sep 2012 – Rev-02

Key Focus Areas

• HSE Management:

The purpose of PDO‟s Health, Safety, and Environment Management System is to manage threats, hazards, events, and effects to health, safety, and the environment in a systematic and structured way. The management of these involves a systematic process of risk identification, assessment / evaluation, control, monitoring, and recovery where necessary.

The above is well documented in PDO code of practice.CP-122PDO Specification SP-1257 describes PDO's requirements for:•  Working on high structures • Scaffolding• Working over water• Lifting operations• Earthworks, roadwork and excavations.

This Specification applies to all activities involving scaffolding (onshore and offshore), working at heights or over water, lifting operations and earthworks, undertaken by PDO, and Contractor/Sub-Contractor personnel authorised to work on behalf of PDO.

Key Focus Areas

• Concurrent Operations :

Concurrent operations” is defined as “The simultaneous execution of drilling/hoist operations / Construction activity and production operations, where there is less than 100m separating the production operation from the drilling/hoist operations / Construction activity “

The following hazards arising from concurrent operations require specific controls and recovery measures at the interface of the two operations: • Mechanical impact from moving equipment or dropped load causing a loss of the integrity of

the production equipment• Flaring / venting from a production station• Uncontrolled or controlled release of hydrocarbons or toxic gasses from production facilities or

drilling rig• Well control problems during Drilling / Hoist operations

The principal controls over hazards arising from concurrent operations are: • Segregation of source and receiver to allow for dispersion;• Impact protection of production facilities• Communication.

PDO specification SP-1220 describes controls over concurrent operations.

Sep 2012 – Rev-02

Key Focus Areas

• Permit to Work System :

The petroleum industry handles large quantities of flammable and toxic materials, so the potential for serious accidents is clear. To prevent these accidents, it is vital that there are safe systems of work operating.

The PDO Health, Safety and Environmental Management System Manual states that the Company will endeavour to protect the health and safety of personnel protect the environment and provide a safe and healthy workplace. The PTW System is an important part of the way that PDO meets the requirements of this Policy.

When incidents do occur, human factors, such as failure to implement procedures properly, are often a root cause. These failures may, in turn, be attributable to a lack of training, instruction or understanding of either the purpose or practical application of the Permit to Work (PTW) system.

A Permit to Work (PTW) system does not exists simply to provide permission to carry out a hazardous job. It is an essential part of a system, which determines how that job can be carried out safely. The Permit is regarded as a statement that all hazards and risks have been eliminated from or controlled in the work area. The issue of a Permit does not, by itself, make a job safe. That can only be achieved by those preparing for the work and those carrying it out. The Permit To Work System forms a key part of the company HSE Management System, and demonstrates compliance with the legal framework of Oman Ministerial Decision 286/ (2008).

PDO procedure PR-1172 describes requirements for PTW system.

Key Focus Areas

• Isolation Philosophy :

The objective of SP-1125 is to specify the design/engineering requirements for isolation of a process section or equipment for carrying out the maintenance or inspection work safely. Control of work and related documents reflecting the operating requirements associated with isolation should be used in conjunction with this SP.  This specification is primarily intended for use by plant designers but it may also be used by operations personnel as a general guide for checking the appropriate positioning of spectacle blinds and spades. This specification primarily describes the requirement of positive isolation, applicability of valved isolations and the correct positioning of spectacle blinds and spades in facility pipework. While typical example applications are described, it is stressed that these are not necessarily specific. It is the responsibility of the user to assess the actual requirements based on the maintenance/inspection philosophy agreed during the conceptual design of the facility.

Key Focus Areas

• Emergency Response :

PDO is committed to maintaining an effective Emergency Response Management System (ERMS) to respond to emergencies and to minimize consequential losses.

PDO Code of Practice, CP- 123, is the top level document in a suite of emergency response documents.

It defines the structure of the emergency response management system in PDO, and describes the various elements that make up the ERMS.

Sep 2012 – Rev-02

Key Focus Areas

• Contract Management :

PDO Code of Practice CP-129 details the principles, on which all Contracting and Procurement activities are to be identified, planned and implemented, in order for each of these key areas of services and materials to be obtained on the best commercial terms.

The implementation of the Contracting Out and Contracting & Procurement policy involves:• Clear definition of factors to be assessed when determining and selecting activities to be

considered for contracting out• The appreciation of lifetime costs• The use of competitive tendering whenever possible • Maximum use of National Products and local resources• The use of Supply Chain Management tools and best practices• Managing sustainable development• Building long term Contracting & Procurement skills in PDO

As part of the drive in PDO for improving the management of contracts, PDO guideline, GU- 546 was developed to assist Contract Holders (also Company Representatives and Company Site Representatives) to manage all contracts under their control.
