Blast Rooms for Ship Blocks and Hull Sections
Ship blocks and hull sections need abrasive preparation space that can handle large marine fabrications, support stands and worker access around complex geometry. Double D Mechanical installs, relocates and services blast rooms and the air, exhaust and utility connections that support surface preparation before coating.

Hull sections can include curved plate, stiffeners, frames and interior pockets that require access from several sides. Room layout should account for the largest section, blast hose reach, support fixtures, door swing and room around workers using lifts or platforms.
Dust Collection and Visibility
Blast room air movement has to pull dust away from the work area while avoiding dead zones around deep corners and internal structure. Dust collector placement, duct routing and return air paths should be coordinated with roof steel, wall openings and nearby production equipment.
Media Flow and Floor Layout
Media recovery planning affects cleanup labor, floor elevation, trench locations and maintenance access. The room should be arranged so spent abrasive can move toward recovery points without trapping material under stands, rails or blocking points.
Coordination With Coating Flow
Blast rooms often feed directly into coating areas, so part movement matters as much as the room itself. Door size, staging space, crane access and transfer routes should be reviewed with the paint booth, mixing area and inspection points in mind.
Walkthrough Details to Prepare
A useful site review starts with the workpiece, the building and the intended production rhythm.
- Largest ship block or hull section dimensions
- Expected support stands, carts or rail system
- Preferred abrasive media and cleanup approach
- Existing dust collector, duct or utility information
Frequently asked questions
What drives blast room size for ship blocks?
The largest section, working clearance, handling method, door opening, support fixtures and access for lifts or platforms all influence the room envelope.
How is dust collection coordinated for marine sections?
Duct and collector placement should consider how dust moves around stiffeners, frames and open compartments, along with available roof or wall routes.
Can an existing blast room be relocated for hull work?
Relocation starts with the room structure, dust collection, recovery floor, controls, utilities, rigging needs and the constraints of the new building location.
What should be ready before a site visit?
Have part dimensions, handling paths, photos of the proposed area, utility information and any existing blast room or dust collector data available.
