Course Description

HVAC systems in oil and gas facilities must operate reliably under extreme ambient temperatures - from desert heat exceeding fifty degrees Celsius to arctic cold below minus forty. Unlike commercial buildings where comfort is the primary goal, oil and gas HVAC serves critical safety and process functions. The presence of flammable gases, vapors, and liquids requires every component - from fans to motors to control panels - to be explosion-proof or purged to eliminate ignition sources. A single HVAC failure can lead to process shutdowns, impairment of safety systems, or catastrophic fires. Offshore platforms add further challenges: salt corrosion, constant vibration from rotating equipment, limited space for maintenance access, and helicopter deck constraints. HVAC design must integrate seamlessly with fire and gas detection systems for automatic shutdown and smoke management. Redundancy - often N plus one or even one hundred percent standby - is standard for critical areas to ensure continuous operation. And because maintenance access is severely restricted on many facilities, equipment must be exceptionally robust and easily serviceable.

What you'll learn in this course?

• Identify key HVAC design requirements specific to oil and gas facilities, including onshore and offshore environments.

• Explain the importance of hazardous area classification and its direct impact on HVAC equipment selection and layout.

• Differentiate between pressurization, purge, and dilution ventilation strategies for hazardous zones.

• Apply relevant industry standards (API, ASHRAE, ISO, NFPA) to HVAC design for oil and gas applications.

• Calculate basic cooling and heating loads considering high sensible heat gains, gas turbine intake conditions, and control room requirements.

• Select appropriate air filtration, corrosion protection, and explosion-proof components for extreme environments.

• Describe energy efficiency measures and life-cycle cost considerations for oil and gas HVAC systems.

Prerequisites

• Basic knowledge of HVAC systems, thermodynamics, ventilation, and industrial facility design

• Familiarity with hazardous-area terminology and engineering drawings is helpful
