Air Make-Up Units for Shipbuilding and Marine Work
Shipbuilding and marine fabrication areas can place high demand on ventilation when coating, blasting and curing equipment are in use. Double D Mechanical installs, relocates and services air make-up units for marine finishing spaces, coordinating replacement air with exhaust, utilities, ductwork and maintenance access.
Discuss your installationAir Replacement for Marine Coating Zones
Marine parts can range from panels and hatches to large sections and support equipment. Exhaust volumes from booths, blast spaces and drying areas should be matched with replacement air that does not disrupt coating work or pull contaminants from adjacent fabrication areas. Layout should account for wide aisles, cranes, material carts and temporary staging.
Ductwork Around Fabrication Constraints
Marine shops often have tall bays, heavy handling equipment, weld zones and changing work envelopes. Intake and discharge duct should be routed around crane rails, roof framing, mezzanines and access routes. Outdoor equipment placement also needs service space and a clean intake location.
Utility Tie-Ins and Controls
Air make-up equipment may need power, fuel, control wiring and connections to booth or exhaust operation. Coordinating those tie-ins early helps align the unit with when coating, blasting or curing equipment is actually running.
Preparation for a Field Review
Have equipment drawings, exhaust fan data, available utility information, roof or wall penetration locations and photos of current ventilation equipment ready. For relocation work, identify which production areas must stay open and where rigging or shutdown windows are limited.
Frequently asked questions
Why do marine coating areas need planned replacement air?
Large exhaust systems can pull a building negative, affect doors and move air from dusty or hot work areas into finishing spaces.
Where can an air make-up unit be placed?
Placement depends on structure, intake air quality, duct routing, utility access, service clearance and the connected exhaust equipment.
What information helps with sizing review?
Booth or room airflow requirements, exhaust fan data, operating schedule, equipment drawings and the number of systems that may run together are useful starting points.
Can duct routing be adjusted around cranes and large parts?
Yes, routing should be planned around crane travel, lift paths, access platforms and the clearances needed for marine assemblies.
