• Install HVAC and ventilation systems aboard ships, including main trunks, branch lines, diffusers, dampers, and access doors.
• Fit, align, and secure components using bolts, rivets, welds, threaded fasteners, clips, and brackets.
• Perform layout and routing aboard vessels in tight or confined spaces while maintaining proper clearances and system performance requirements.
• Coordinate installations with other trades (pipefitters, electricians, joiners, welders) to avoid conflicts and maintain schedule.

• Inspect and diagnose issues with existing ducting or sheet metal systems during ship repair, conversion, or overhaul periods.
• Remove, modify, and replace damaged or obsolete components while adhering to shipyard safety and QA procedures.
• Perform leak tests, airflow checks, and system verifications as required.

• Operate according to ABS, NAVSEA, USCG, and shipyard-specific standards, ensuring all work meets specification and inspection requirements.
• Complete work packages, production reports, and material usage documentation.
• Follow strict QA/QC protocols, including weld inspections, dimensional checks, and system fit-ups.

• Comply with all shipyard safety procedures, lockout/tagout, confined space entry, fall protection, and hot-work requirements.
• Maintain clean, hazard-free workspaces aboard vessels, in shops, and on dry docks.
• Use appropriate PPE including respirators, eye protection, gloves, and hearing protection.

• Proven experience as a sheet metal mechanic or fabricator, preferably in a shipyard or marine environment.
• Ability to read complex drawings, schematics, and fabrication blueprints.
• Proficiency with sheet metal tools, machines, and installation techniques.
• Physical ability to climb, kneel, crawl, and work in confined or elevated spaces.
• Strong understanding of trade math, measurements, and layout techniques.

• Completion of a Sheet Metal or Shipfitter apprenticeship program.
• Experience with Navy vessel construction (e.g., LPD, DDG, CVN, SSN, LNG carriers).
• Knowledge of NAVSEA Standard Items and shipyard work package procedures.
• OSHA 10/30, Firewatch, or Confined Space certifications.

• Work performed aboard ships (new construction and repair), in industrial shops, on dry docks, and occasionally outdoors.
• Exposure to noise, heat, dust, metal fumes, and cramped environments.
• Schedule may include overtime, shift work, and weekend assignments based on project needs.

• Shears, brakes, rolls, presses
• Hand tools: snips, seamers, hammers, rivet guns
• Measuring instruments: tape measures, squares, calipers
• Portable power tools and pneumatic tools
• Welding and brazing equipment (depending on job level)
