Blast-It-All Offshore and LNG Modules
Offshore and LNG module fabrication brings large frames, dense weldments, pipe racks and skids into the finishing area. Double D Mechanical supports Blast-It-All blast room installation, relocation and service by coordinating enclosure fit, exhaust, make-up air, abrasive handling, utility tie-ins and maintenance access.

Module Envelope And Bay Layout
Module frames can be tall, wide and irregular, with handrails, pipe supports, base plates and lifting points that complicate entry into a blast room. The layout should be checked against crane coverage, transporter lanes, door swing, staging space and the clean path toward coating or inspection. The goal is a room location that supports production instead of creating a pinch point.
Abrasive Cleaning Around Dense Frames
A Blast-It-All blast room used for module components needs practical routing for blast hoses, recovery equipment and dust collection. Dense assemblies can trap spent media and slow cleanup, so floor recovery, operator access and air movement should be considered before the room is set. Service platforms and collector access should not block the material path.
Exhaust And Replacement Air Balance
Large blast rooms remove a significant volume of air from the building. Exhaust duct routing, collector location, air intake openings and make-up air equipment should be coordinated with welding, coating, assembly and warehouse areas. That planning helps limit pressure issues that can affect doors, adjacent booths and worker comfort.
Utility And Trade Sequencing
Installation work may involve compressed air, electrical feeds, lighting, controls, structural supports, fire protection interfaces and roof or wall penetrations. Early sequencing helps avoid conflicts between ductwork, cranes, pipe racks and cable trays. Double D Mechanical can review what needs to be ready before equipment is unloaded or moved into place.
Frequently asked questions
What makes offshore module blast rooms different from smaller part rooms?
The workpieces are larger and often more congested, so the room must account for handling equipment, trapped abrasive, operator reach, duct routing and longer cleanup cycles.
What information helps before a Blast-It-All room relocation?
Useful items include existing room dimensions, panel condition, collector data, reclaim layout, electrical requirements, compressed air capacity and drawings of the proposed bay.
How should coating areas be considered with the blast room?
The blast room should feed the coating area without crossing clean and dirty traffic. Staging, masking, inspection and transfer lanes should be planned as part of the same workflow.
Can exhaust ductwork be routed through an existing crowded bay?
It may be possible, but the route has to be checked against cranes, roof structure, sprinkler piping, overhead utilities, access doors and maintenance clearance.
