Rohner for Ship Blocks and Hull Sections
Ship blocks and hull sections bring large geometry, weld seams, stiffeners and access challenges into the finishing area. Rohner equipment for this type of work can involve large equipment booths, blast rooms, paint mixing rooms, make-up air, exhaust and related mechanical connections. Double D Mechanical installs, relocates and services the air, exhaust, booth, oven and utility systems around these heavy marine fabrication workflows.

Hull Section Fit And Support
The first planning step is the real work envelope, including stands, lifting lugs, staging cradles and any temporary access platforms. Large sections need enough clearance for coating around edges, stiffeners and recessed areas. Door openings, crane paths and floor loading zones should be reviewed with the booth or blast room footprint.
Surface Preparation Boundaries
Marine sections may require abrasive blasting, cleaning, masking and coating in separated zones. Blast media, dust and overspray should be kept from clean coating and inspection areas where the facility layout allows it. Mechanical routing should support that separation without placing ductwork or utilities where sections need to move.
High-Volume Exhaust Coordination
Large booth and blast areas can require substantial exhaust and replacement air. Fan placement, duct paths, intake locations, heater connections and roof penetrations should be planned as one system. That coordination helps the finishing space work with building pressure, adjacent bays and maintenance access.
Access After Installation
Fans, lights, filters, doors, controls, dampers and burner components need reachable service points after the equipment is surrounded by marine fabrication activity. Relocation or service work should account for the safest route to remove panels, reach ducts and isolate utilities without blocking critical material flow.
Frequently asked questions
What dimensions matter for ship block finishing equipment?
Overall length, width, height, stand height, platform clearance, door approach and crane or transporter paths are all useful for layout review.
How should blast and paint areas be arranged?
The best arrangement reduces cross traffic between abrasive work, cleaned surfaces, coating operations and inspection. Existing bay limits and handling equipment usually shape the final layout.
What utilities should be checked for large marine sections?
Review electrical service, compressed air, gas if heat is used, control wiring, exhaust routes, make-up air intake locations and roof or wall access.
Can existing equipment be relocated for larger sections?
It may be possible after checking panel condition, door size, fan capacity, duct condition, floor space, utility reach and the physical removal path.
What should maintenance teams plan around?
Keep access to filters, lights, fan bearings, dampers, burners, control panels and duct cleanout points from the finished operating aisles.
