The Mid-Level Ventilation Systems Engineer is responsible for the design, analysis, and optimization of ventilation systems across marine and offshore platforms, with a focus on airflow performance, contaminant control, and regulatory compliance. The role requires independent handling of ventilation design tasks, coordination with multi-disciplinary teams, and implementation of safety-critical airflow systems in environments such as machinery spaces, accommodation zones, hazardous compartments, and control rooms.
Design and analyze supply, exhaust, and recirculation ventilation systems for diverse shipboard compartments.
Conduct airflow modeling, ductwork layout, pressure drop analysis, and fan sizing using manual methods and engineering software.
Specify and select ventilation components including fans, dampers, silencers, filters, and HVAC duct materials suitable for marine environments.
Prepare and review ventilation schematics, airflow zoning diagrams, P&IDs, and bill of materials (BOMs).
Perform hazard and contaminant mitigation analysis, including air dilution, toxic gas extraction, smoke control, and explosion risk ventilation strategies.
Ensure ventilation designs meet SOLAS, IMO, ASHRAE, ISO, and classification society standards (ABS, DNV, etc.).
Collaborate with shipyard personnel, contractors, and engineers in the installation, testing, balancing, and commissioning of ventilation systems.
Conduct or support site inspections, audits, and airflow balancing procedures, especially in hazardous or controlled zones.
Mentor junior engineers and provide quality reviews of draft deliverables.
Document engineering analyses, equipment selections, and conformance reports for submission to clients and regulatory bodies.
Ventilation System Design and Integration
– Deliver reliable and efficient airflow systems in marine vessels, integrating with fire suppression, HVAC, and life support systems.
Contaminant and Risk Control
– Develop ventilation strategies for smoke extraction, VOC mitigation, engine room exhaust, and hazardous area control.
Regulatory Compliance and Safety Assurance
– Maintain full compliance with marine safety regulations and ensure ventilation supports personnel health and survivability in critical environments.
Cross-Disciplinary Collaboration
– Work closely with mechanical, structural, and automation teams for seamless integration of ductwork, controls, and mechanical systems.
Bachelor’s degree in Mechanical Engineering, Marine Engineering, or Environmental Systems Engineering.
3–6 years of experience in ventilation system design, preferably in marine, offshore, or heavy industrial sectors.
Proficient in duct design, airflow and static pressure calculations, and fan selection.
Experience with CAD and modeling tools such as AutoCAD, Revit MEP, and airflow simulation tools (ANSYS Fluent, FDS, or similar).
Familiarity with marine regulatory frameworks (IMO, SOLAS), ventilation fire safety standards, and class society rules (ABS, DNV, etc.).
Strong documentation, communication, and problem-solving skills.
Willingness to travel to shipyards or offshore sites for installation reviews and testing.
Hands-on experience with smoke control systems, hazardous ventilation, or engine room exhaust systems.
Understanding of HVAC control integration, fire dampers, gas detection interlocks, and emergency ventilation scenarios.
Previous experience supporting ventilation systems on naval ships, LNG carriers, or offshore drilling units is a plus.
Familiarity with ISO 15138 (HVAC for marine and offshore) or ASHRAE 62.1/15 is advantageous.
