ABS Blast for Ship Blocks and Hull Sections
Ship blocks and hull sections bring large weldments, deep profiles and heavy handling into the finishing area. ABS Blast equipment for this work can include blast rooms, abrasive blast booths and media reclaim systems used before protective coating. Double D Mechanical installs, relocates and services the mechanical connections around these finishing systems.

Block Size And Handling Path
Hull sections need a clear route from fabrication into blasting and onward to coating or assembly. Layout planning should account for cranes, transporters, door openings, staging space, operator reach and the swing of large sections as they enter the room.
Blast Media Recovery Flow
Media reclaim equipment should support the way operators move around webs, stiffeners, curved plates and internal corners. Recovery pits, screw conveyors, separators and dust collection paths need service clearance without blocking material movement.
Ventilation For Marine Weldments
Large marine pieces can create shadowed zones where dust and overspray linger. Exhaust, intake placement, replacement air and booth pressure should be reviewed with the actual block geometry, coating steps and nearby shop activity in mind.
- Provide maximum block length, width, height and weight.
- Identify cranes, carts or transporters used to move each section.
- Share proposed exhaust routes, make-up air locations and utility points.
Access Around Fans And Doors
Shipyard finishing areas need room to maintain doors, lights, dust collectors, reclaim components, fans and ductwork. Service paths should remain open after staging racks, hoses, blast pots and inspection areas are in place.
Frequently asked questions
What matters most when placing blast equipment for ship blocks?
The largest section size, handling route, crane coverage, door clearances, operator access and the next step in production all affect placement.
Can a media reclaim system be planned around irregular hull shapes?
Yes. The reclaim approach should match how media falls from frames, stiffeners and curved surfaces so cleanup does not slow the finishing flow.
Why is replacement air important for marine finishing areas?
Blast and paint exhaust remove a large volume of air. Replacement air helps keep the surrounding shop from pulling dust or fumes into unwanted areas.
What should be ready before a site visit?
Drawings or photos of the proposed area, maximum section dimensions, handling methods, coating sequence, utility locations and roof or wall constraints are useful.
