Blast Rooms for Offshore and LNG Modules
Offshore and LNG modules need surface preparation space that can handle heavy structural frames, skids and assemblies before protective coating. Double D Mechanical installs, relocates and services blast rooms and the air, dust collection and utility connections that support module fabrication finishing.
Discuss your installationRoom Fit for Module Assemblies
Module frames can include tall steel, pipe supports, platforms and protruding brackets. The blast room should provide clearance for the full assembly, the support method, blast hose movement, access equipment and door openings.
Air Movement Through Open Frames
Open steel frames can let dust move through the workpiece, while dense sections can slow air in pockets. Dust collection and duct layout should be planned around the shape of the module and the likely blasting positions.
Recovery Floor and Cleanup Strategy
Media recovery should match the way parts are staged and moved. Floor sweeps, trenches, grates or recovery points need to avoid interference with stands, rails, carts and forklift traffic while leaving room for service work.
Link to Downstream Coating
Blast room placement should support the path to paint booths, mixing rooms and inspection areas. Large modules should be able to leave preparation without crossing unnecessary traffic or blocking maintenance access.

Frequently asked questions
What determines blast room layout for offshore modules?
The module size, support fixtures, handling equipment, access method, door openings and dust collection path all shape the room layout.
Why does open-frame construction affect blasting airflow?
Air and dust can move through frame openings differently than around solid surfaces, so collector placement and duct routing need careful coordination.
Can media recovery be included in the blast room plan?
Yes, recovery equipment can be coordinated with the blast room floor, dust collection, abrasive cleaning and service access requirements.
What information should be available for a site visit?
Module drawings, staging method, building photos, utility locations, roof or wall route options and existing equipment details are useful.
