HVAC Engineer (Offshore)

Position Overview

The HVAC Engineer is responsible for the design, specification, and technical support of heating, ventilation, and air conditioning systems for offshore installations. This role ensures that accommodation modules, control rooms, and equipment rooms maintain appropriate environmental conditions for personnel safety, equipment reliability, and regulatory compliance, including hazardous area pressurization and gas detection integration.

Key Responsibilities

• Design and specify HVAC systems for offshore platforms including accommodation, control rooms, switchgear rooms, and compressor shelters
• Perform heating and cooling load calculations for various offshore module types and climatic conditions
• Design pressurization systems for safe areas to prevent ingress of hazardous gases per API 14G and related standards
• Specify HVAC equipment including air handling units, chillers, heaters, fans, and filtration systems for offshore duty
• Integrate HVAC systems with F&G detection, ESD, and ICSS for emergency response (shutdown, pressurization loss, gas detection)
• Conduct ductwork design, airflow balancing, and smoke extraction system design
• Perform Computational Fluid Dynamics (CFD) analysis for ventilation design and gas dispersion assessment
• Support HVAC system commissioning including airflow measurement, pressurization testing, and temperature/humidity verification
• Develop HVAC maintenance strategies and support troubleshooting of operational issues
• Ensure HVAC design complies with maritime and offshore regulations (SOLAS, NORSOK, DNV) and health/comfort standards
• Review vendor HVAC packages and coordinate with architectural and structural disciplines

Qualifications

Required

• Education: Bachelor's degree in Mechanical Engineering or Building Services Engineering
• Certifications: OPITO BOSIET/FOET for offshore; relevant HVAC professional certifications preferred
• Experience: Minimum 5 years in HVAC engineering with at least 2 years in offshore or marine environments
• Technical Skills: HVAC system design (heating/cooling load, ductwork, pipework), pressurization system design, F&G integration, CFD analysis, offshore HVAC codes (NORSOK S-001, API 14G, DNV), psychrometric analysis

Preferred

• CFD modeling experience for gas dispersion in offshore modules
• Experience with HVAC on FPSO or FLNG facilities
• Knowledge of refrigerant phase-out regulations and natural refrigerant alternatives
• Experience with clean room or laboratory HVAC design for offshore
