Rapid Engineering for offshore and LNG modules
Offshore and LNG module finishing often involves heavy frames, skid bases, pipe racks and coated assemblies with tight hold points and demanding handling requirements. Double D Mechanical helps install, relocate and service the paint booth, blast room, exhaust and air make-up connections that support those workflows.

Module Frame Handling Space
Module frames and skid assemblies need space for rigging, forklifts, cranes, rotators, stands and inspection access. Mechanical equipment placement should protect those routes while keeping the coating zone clear of unnecessary obstructions.
- Map the tallest and widest module envelope before locating duct drops or air discharge points.
- Check crane hook paths, floor anchors and temporary stand locations.
- Preserve maintenance access to fans, filters, burners, valves and control panels.
Air Make-Up Under Heavy Exhaust Loads
Rapid Engineering air make-up units may be used to replace air removed by paint booths, prep areas and large exhaust systems. Planning should consider building pressure, intake placement, heated air distribution and how the unit will be reached for routine service after surrounding fabrication equipment is installed.
Prep-To-Coat Production Flow
Large energy modules may pass through blast rooms, media recovery areas, paint booths and cure or dry zones. Double D Mechanical coordinates exhaust ductwork, make-up air, utility runs and penetrations so the mechanical work supports movement between preparation, coating and inspection.
Field Readiness For Installation
Before field work starts, the best inputs are current drawings, equipment tags, duct routes, utility capacities, roof structure information and photos of the proposed equipment path. Clear shutdown windows and trade sequencing help avoid conflicts with electrical, fire protection, structural and controls work.
Frequently asked questions
Why does module geometry matter for booth air planning?
Dense steelwork can block airflow, create pockets and limit operator reach. The layout needs to account for frames, pipe racks, deck levels and areas where coating access is difficult.
What utility connections are commonly reviewed?
Typical reviews include gas or electrical service, control wiring, compressed air, exhaust fan power, lighting circuits, interlocks and roof or wall penetrations for ductwork.
Can air make-up equipment be added to an existing finishing line?
It can be considered when the existing building, roof structure, utilities and controls can support the equipment and when the discharge path works with the booth exhaust pattern.
What should be documented before relocating finishing equipment?
Document equipment condition, duct sections, controls, utility disconnects, support steel, access constraints and the route from the old location to the new installation point.
