HKIE Professional Assessment - Gas Discipline study guide
HKIE Professional Assessment - Gas Discipline · Work through your exam, one topic at a time.
The HKIE Professional Assessment in the Gas Discipline is the route by which an engineer demonstrates the competence required for professional membership of the Hong Kong Institution of Engineers in gas engineering. It is intended for engineers working in gas supply, installation, utilisation, safety or related fields who have completed the required academic and training stages. The HKIE Professional Assessment - Gas Discipline study guide has 10 sections and about 4,275 words.
01Gas supply systems and network design
This domain examines how you plan, size and safeguard town gas and LPG distribution systems from the city gate or bulk installation to the consumer meter. The exam expects pressure-tier thinking, demand diversity, hydraulic checks and asset-integrity awareness, not just pipe sizing.
482 words, about 2 min02Gas properties, combustion and utilisation
Expect calculations and explanations linking gas composition to calorific value, air requirement, flame behaviour and appliance performance. You should be able to move between gross and net calorific value, stoichiometry, excess air and Wobbe index.
465 words, about 2 min03Gas installation design and pipework sizing
This domain assesses whether you can design consumer pipework that delivers the required flow at an acceptable pressure, with correct materials, joints, isolation, protection and accessibility. The exam rewards a clear sizing method and awareness of the applicable GU code and utility requirements.
435 words, about 2 min04Ventilation, flueing and indoor air quality
The exam tests whether you can provide combustion air, remove products of combustion safely, and protect indoor air quality in dwellings, commercial kitchens and plant rooms. Flue design and ventilation are inseparable: a flue that cannot draft is a carbon-monoxide hazard.
407 words, about 2 min05Gas safety, hazard and risk management
This domain asks how you identify, evaluate and control gas hazards, and how you respond when controls fail. Expect questions on risk assessment, gas detection, emergency isolation, purging, permits-to-work and incident reporting under Hong Kong's gas safety regime.
395 words, about 2 min06Codes, standards and regulatory framework (Hong Kong)
The exam tests your command of the Hong Kong statutory framework and the supporting codes. You must know which instrument creates a duty, which code gives technical guidance, and which authority enforces it.
409 words, about 2 min07LPG and LNG installations and bulk storage
This domain tests your understanding of LPG and LNG as stored fuels: properties, containment, pressure and temperature control, separation distances, fire protection and the differences between cylinder, bulk and cryogenic installations. LPG is stored as a liquid under pressure.
414 words, about 2 min08Commissioning, testing, inspection and maintenance
This domain examines the evidence trail from installation to safe operation: strength and tightness testing, purging, commissioning checks, inspection and planned maintenance. The exam expects practical test sequences and the reasons behind them.
408 words, about 2 min09Professional practice, ethics and project management
This domain tests judgement as much as knowledge: how you act when safety, cost, programme and client pressure conflict. Expect scenario questions on competence, conflicts of interest, documentation, escalation and handover.
412 words, about 2 min10Energy efficiency, environment and emerging low-carbon gases
This domain links gas utilisation to carbon and energy performance: combustion efficiency, condensing technology, demand reduction, emissions and the introduction of hydrogen, biomethane and LNG. Expect calculations and an understanding of safety and interchangeability limits.
