RTT Finishing Solutions Offshore And LNG Module Booth Work
Offshore and LNG module finishing often involves heavy frames, skids, pipe supports, equipment bases and structural assemblies that need durable protective coatings. Double D Mechanical installs, relocates and services paint booths, blast rooms, make-up air systems, exhaust ductwork and utility connections used with RTT Finishing Solutions equipment.

Module Geometry And Support Stands
Energy modules can combine heavy steel, pipe routes, platforms and equipment mounts in one workpiece. The finishing layout should account for support stand height, lift points, masking access, aisle clearance and the reach needed to coat complex corners and recessed areas.
Blast To Coating Transfer
Abrasive blasting, media recovery, dust collection and coating should be arranged to limit extra handling. Keeping blasted parts moving through a controlled path helps reduce contamination risk and makes it easier for inspectors and painters to work around the same fabrication schedule.
Air Units, Ducts And Roof Openings
Large booths and blast rooms need coordinated exhaust and replacement air. Duct supports, fan locations, roof curbs, wall openings, heater connections and control wiring should be identified early so structural and electrical work can proceed in the right order.
Working Around Plant Utilities
Module fabrication areas can be dense with welding power, compressed air, gas piping, cranes and temporary services. Mechanical installation should be sequenced with those constraints in mind, especially where exhaust duct or make-up air equipment crosses active production zones.
Records To Gather Before The Visit
Before a site visit, collect module size ranges, coating process steps, blast requirements, current bay drawings, utility maps, roof information and photos of the proposed booth location. Notes from maintenance staff can also identify access problems that are easy to miss on drawings.
Frequently asked questions
What makes offshore and LNG modules challenging to finish?
They are often large, heavy and geometrically complex, with platforms, pipe supports and recessed surfaces that affect booth clearance, spray reach and handling.
Should the exhaust route be planned before equipment delivery?
Yes. Exhaust duct paths, fan placement, supports and building openings can drive installation sequencing and coordination with other trades.
How does make-up air affect module coating areas?
Make-up air helps replace exhausted air and supports more predictable airflow through the enclosure, reducing pressure problems in nearby production areas.
What maintenance access should be protected?
Protect access to filters, fans, dampers, heaters, lights, controls, disconnects and utility shutoffs so the system can be serviced after production fixtures are in place.
What should be included in a relocation review?
Include the existing equipment condition, disassembly path, new floor layout, duct changes, utility changes, air unit location and clearances around service points.
