HVAC Design for Oil and Gas Facilities
Course Highlights

This online engineering PDH course will help explain the complexities of HVAC design for offshore installations and how to go about carrying out the selection of a proper system and related equipment.


Oil & Gas (O&G) facilities are fraught with numerous challenges related to health and safety, logistics, economics, quality assurance and overall performance. HVAC design for such facilities needs special considerations not only to minimize the potential loss to capital investment but also to isolate the personnel from life-threatening environment. The main objectives of HVAC systems in O&G facilities include:

  1. Maintain acceptable working and living environment for personnel and non - destructive conditions for equipment.
  2. Prevent ingress of potentially explosive/toxic gas-air mixtures into non-hazardous areas, electrical switch rooms and equipment rooms.
  3. Prevent formation of any combustible mixture and maintain an atmosphere where the gas/air mixture is kept below LEL during normal operation.
  4. Provide dilution ventilation for all enclosed hazardous areas in order to reduce the risk from build-up of potentially explosive/toxic gases within these spaces.
  5. Prevent smoke spreading and keep enclosed escape ways free of smoke in case of fire.


This 4 PDH online course is applicable to mechanical and HVAC engineers, process engineers, architects, building designers, contractors, energy auditors, facility managers who are involved in the design and installation of HVAC for oil and gas facilities.
