RTT Finishing Solutions Ship Block And Hull Section Booth Work
Ship blocks and hull sections bring large fabricated steel shapes into blast and coating areas before or during vessel assembly. Double D Mechanical installs, relocates and services large paint booths, blast rooms, make-up air, exhaust ductwork and utility connections used with RTT Finishing Solutions equipment for marine fabrication work.

Marine Section Movement And Clearance
Hull sections and module pieces can be wide, tall and irregular. Booth and blast room planning should account for cranes, transporters, support stands, door openings, staging areas and the space needed for workers to reach welds, edges and underside details.
Surface Prep Before Protective Coating
Marine fabrications often require abrasive preparation before primer or coating work. The blast area, media reclaim, dust collection, paint booth entry and masking space should be arranged so blasted steel does not sit in a dirty or congested traffic path.
Exhaust Routing For Large Steel Work
Big coating enclosures require careful exhaust routing and replacement air planning. Fan locations, duct supports, wall or roof openings, make-up air discharge and building pressure should be reviewed with the surrounding fabrication layout in mind.
Utility Coordination Around Fabrication Bays
Large marine work areas may already be crowded with welding leads, compressed air drops, cranes, gas lines and electrical service. Installing or relocating finishing equipment calls for clear trade sequencing so mechanical connections do not conflict with production infrastructure.
Access For Filters, Fans And Lights
Service points should remain reachable after stands, carts and fixtures return to the bay. Maintenance access for filters, lights, fans, dampers, controls and air units helps keep the system usable during active fabrication schedules.
Frequently asked questions
What should be reviewed before installing a booth for hull sections?
Review the largest section size, support method, handling path, crane coverage, door openings, floor space, utility tie-ins and exhaust route options.
Can blast and paint areas share planning information?
Yes. Blast preparation, dust collection, coating, masking and inspection are connected steps, so layout decisions in one area can affect the other.
Why is replacement air part of the discussion?
Exhaust fans remove air from the building. Make-up air helps offset that removal and supports stable airflow through the booth or enclosure.
What makes service access difficult in marine fabrication bays?
Large stands, irregular parts, welding equipment and temporary staging can block filters, fans and panels unless access paths are protected during layout planning.
What should be ready for a site walkthrough?
Prepare current bay photos, part dimensions, movement paths, utility locations, roof or wall details, and any known conflicts with cranes, sprinklers or electrical equipment.
