Blueprint reading: Interpret ship drawings and HVAC layouts to plan duct installation.
Fabrication: Cut, bend, and shape sheet metal or prefabricated duct sections using hand tools, plasma cutters, and bending machines.
Installation: Fit ducts into confined ship compartments, align them to specifications, and secure with brackets, supports, and welding/tack welding.
Ventilation systems: Ensure ducts connect properly to fans, blowers, and exhaust systems for machinery spaces, cabins, and cargo holds.
Quality checks: Inspect duct joints, seals, and alignments to meet marine safety standards (ABS, NAVSEA, ISO).
Maintenance: Repair or replace damaged ducts during ship refits or maintenance cycles.
