Pauli Systems for Offshore and LNG Modules
Offshore and LNG modules bring heavy frames, pipe supports, skids, access steel and complex coating requirements into fabrication finishing areas. Pauli Systems equipment in this category includes blast rooms, abrasive blast booths and media reclaim systems. Double D Mechanical installs, relocates and services the mechanical connections for preparation, coating, exhaust, make-up air and utilities.

Module Frame Envelope
Module frames should be reviewed for length, width, height, skid supports, lifting points and any attached pipe or structural projections. The path into the room may need clearance for transporters, cranes or fork trucks in addition to the workpiece itself. Operators need room to reach inside bracing, around base plates and along elevated members.
Surface Prep In Fabrication Flow
Blast rooms should be arranged with fit-up, weld, masking, coating and inspection steps in mind. Dust and spent media need to stay away from cleaned surfaces and nearby assembly work. If small components are prepared near large modules, racks and carts should be planned so they do not disrupt the main module movement path.
Air, Dust And Heat Coordination
Module finishing can create heavy exhaust, dust collection and replacement air requirements. Duct routing, fan locations, heater connections, controls, compressed air and wall or roof openings should be coordinated before setting equipment. Double D Mechanical can align the mechanical work with the building layout and production sequence.
- Provide module dimensions with skids, lifting lugs and temporary supports included.
- Identify where blasting, masking, coating and inspection occur in the plant.
- Show crane coverage, transporter lanes, utility sources and roof constraints.
Service Points Near Large Skids
Large skids can block equipment access if filters, lights, fans, reclaim components and controls are placed only for installation convenience. Maintenance paths should be reviewed from normal working positions, not just from an empty bay. Relocation work should also document existing duct, panels, media handling equipment and utility terminations.
Frequently asked questions
What module information is needed for blast room planning?
Provide maximum dimensions, skid support details, projections, lifting method, transporter path and surfaces that need operator access.
Why coordinate blast equipment with fabrication flow?
Modules often move through weld, prep, coating and inspection in large steps, so the equipment should support that direction of travel.
What utilities are typically reviewed?
Electrical service, compressed air, heat source, controls, exhaust routing and make-up air locations are commonly reviewed.
Can smaller parts be handled near module work?
They can be included when racks, carts and staging locations are arranged so they do not block large module movement.
What service access should be protected?
Protect access to reclaim systems, dust collection connections, filters, fans, dampers, lights, doors and control panels.
