7.2 Gas Infrastructure Safety

We strive for the highest safety standards for

our gas infrastructure. The global standards we

adhere to include the ISO 55001-certified Asset

Management System across our gas production

plants and our transmission and distribution

network. At all Hong Kong plants, our equipment,

networks and processes are regulated by the

government’s Electrical and Mechanical Services

Department (EMSD). We work closely with the

Long-established design and engineering

principles – and robust operating and

maintenance practices – ensure our processes

and assets are efficient and effective and, at the

same time, protect people’s lives and maintain the

safety of the gas supply. It is vital for us to be able

to manage the risks associated with large-scale

projects or modification work. To achieve this, we

conducted a Process Hazard Analysis to establish

the potential cause and impact of incidents and

critical controls. An example of this in practice

is the six-stage Hazard Studies approach, which

is adopted by our gas production department for

identifying and documenting critical hazards,

as well as developing measures to control or

mitigate major risks.

By improving our assets, such as replacing

essential equipment or investing in technology,

we help maintain safety standards. We shall

install an additional naphtha cooler and

retractable grounding assembly at our existing

naphtha pumping system and naphtha tanks

respectively, reducing the risk of fire. We also

intend to install a backup export gas line at the

Phase 2 gas production plant to increase gas

supply reliability.

EMSD to create strategic plants which include a

facilities utilisation framework and a preventative

maintenance index to guarantee optimum

safety standards. An example of this is the large

investment we have made to replace essential

equipment at our Tai Po Gas Production Plant, as

well as integrating ultrasonic and flame detector

technology to monitor and control leaks.
