The Senior Sheet Metal Technician leads the fabrication, installation, and inspection of complex HVAC ductwork systems aboard marine vessels. The role requires expert-level understanding of marine ventilation standards, coordination with multi-trade teams, and the ability to supervise and train junior personnel. The technician ensures that all ducting systems meet dimensional accuracy, airflow performance, and classification compliance.
Leadership in Installation and Field Fit-Up of Marine HVAC and Ventilation Systems
Oversee and execute the precise layout, fabrication, and onboard fit-up of ducting in critical zones such as machinery spaces, accommodations, and fire-rated boundaries in compliance with ABS, IMO, and SOLAS requirements.
Lead the layout, cutting, forming, and assembly of complex ductwork systems from galvanized steel, stainless steel, and aluminum sheet metals.
Supervise the installation of HVAC components, including ducts, dampers, access panels, and air terminals across vessel compartments.
Interpret detailed HVAC system drawings, isometrics, and coordination diagrams to guide duct routing and transitions.
Ensure proper support, vibration control, and airtight joint sealing as per class and shipyard standards.
Perform field measurements and modify ducts for accurate fit-up in confined and irregular spaces.
Coordinate closely with welding, insulation, piping, and electrical teams to avoid system clashes and maintain build schedules.
Conduct inspections for alignment, airflow clearance, and installation compliance with SOLAS fire boundary and smoke extraction requirements.
Mentor junior and mid-level sheet metal technicians in fabrication techniques, blueprint reading, and job safety.
Prepare ductwork and related zones for testing, balancing, and commissioning activities.
Ensure adherence to shipyard safety procedures, confined space protocols, and PPE standards.
Technical diploma or trade certification in Sheet Metal, HVAC Installation, or Marine Mechanical Systems.
Minimum of 6 years of hands-on experience in marine HVAC ductwork fabrication and installation, with supervisory exposure.
Mastery of sheet metal layout, forming, and installation methods specific to marine environments.
Strong understanding of HVAC system design principles, airflow requirements, and marine ventilation codes.
Familiar with classification and safety standards including ABS, IMO, USCG, SOLAS, and relevant fire protection guidelines.
Ability to read and interpret fabrication drawings, HVAC schematics, and coordination drawings.
Experience in HVAC outfitting of naval vessels, offshore platforms, or cruise/passenger ships.
Excellent leadership, problem-solving, and communication skills.
Experience supporting commissioning teams during HVAC system testing and verification.
Familiarity with HVAC integration in modular construction or block-stage assembly processes.
