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.
17. 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-122
PDO 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.

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.
21. Sep 2012 – Rev-02
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.
22. 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.
