Overview
HSSE Policy
Safety Measures- Functions of OISD
IMS for CGD

3. 

Effective health, safety and security performance across CGD
operations depends on a commitment to maximize awareness of
these risks at every level of the organization.
Zero injury goal could be achieved by;



Preventative maintained
Internationally accepted good practice
Everyone’s responsibility and duty to intervene to prevent unsafe actions
and to reinforce good behaviors through demonstrating HSE leadership.

4. 


Management decisions reflect our HSE intentions
HSE management system reflects best industry practice and is
properly resourced
Continuously improvement of HSE performance by acting on
lessons learnt ;
to avoid work related ill health, accidents, and incidents,
 to prevent pollution and
 to minimize environmental emissions, waste and energy use.


Ensure and maintain compliance with all legal
requirements to operate business and which relate to its
environmental aspects and OH&S risks.

5. 






Provide direction, education, training and supervision to ensure all
employees are competent and understand their accountabilities, the
required behavior and the consequences of non compliance
Ensure that contractors and suppliers understand their HSE
accountabilities and required behavior, share our aspirations and are
aware of the consequences of non compliance. Sharing and learn from
each other’s experiences
Work with partners to achieve internationally accepted good practice in
HSE and learn continually from each other’s experiences
Adopt a risk based approach to the design, construction and operation
of our facilities across their life cycles
Involve and consult all our Stakeholders and take into account their
concerns on HSE
Report on our HSE objectives together with performance and work with
industry and government agencies to improve HSE practices
Policy is used as a framework for setting and reviewing Environmental
and OH&S objectives and targets.

6. Injury and incident free organization, this means:
Trust - Developing trust through fair treatment
 Confidence - Ensuring people feel confident to act
 Empowerment - Empowering people to take action on safety
 Zero Tolerance - Never compromising on safety and taking action on

11. Integrity management plan for city gas distribution networks
through
 Evaluating the risk associated with city gas distribution
networks and effectively allocating resources for prevention,
detection and mitigation activities.
 Improving the safety of city gas distribution networks so as to
protect the property, public and environment.
 Bringing more streamlined and effective operations to minimize
the probability of pipeline failure.

12. 

Enquiries in accidents
Reviewing
Specify critical drawing/Lauouts

13. 



Ensuring the quality of CGD network integrity in all areas which
have potential for adverse consequences
Promoting a more rigorous and systematic management of CGD
network integrity and mitigate the risk
Increasing the general confidence of the public in operation of
CGD network

15. Initial Data Gathering
Threat Identification
Evaluation of Threat
Consequence and
Impact Analysis
Four aspects should be visualized during data collection:
Data alignment, Data history, Data Normalization, Data accuracy and confidence
Time Dependent Threats-- 1) External Corrosion 2) Internal Corrosion
Stable Threats--Manufacturing related defects, Welding /fabrication related, Equipment
Time independent Threats- Third party /mechanical damage, Incorrect operational procedure
Identification of High-consequence area (HCA)
Risk Assessment/
Evaluation
Risk rating = Probability rating X Consequence rating
Integrity
Assessment
Hydro testing before commissioning at test pressure as per T4S standard
External Corrosion Direct Assessment(ECDA)
Cathodic protection system surveys etc.
Response & Mitigation
Performance Plan &
Measures
1) Process measures
2) Operational measures
3) Direct integrity measures

17. 







High transmission pressures
Remote location of transmission pipelines (high emergency response
time)
Distribution lines pass through thickly populated areas
No control of source of ignition near pipelines
Pipelines are buried; hence maintenance and leak detection is tedious
Consumers are not well equipped to deal with exigencies
Unplanned/ un-notified dredging by external agencies
Use of non-standard fittings by the customer (CNG kits)

18. 








Use of SCADA/ GIS to map remote pipeline networks
Automatic isolation valves
Customer education programs
Proper route mapping and marking as hazardous zone
Proper Leak Detection Equipments to prevent major disasters
Synchronization with local bodies/ agencies to avoid pipeline
damage, notifying fire brigade about new gas pipeline routes in a
given area
Undertake Asset Integrity Management (AIM) of all equipments
Follow design/ operating standards as prescribed by OISD
Prepare robust Disaster Management Plan (DMP) to deal with
disasters
