Coating Systems for Offshore Module Fabrication
Offshore and LNG module fabrication brings large frames, pipe racks, skids and assembled structures into surface preparation and protective coating. Double D Mechanical supports blast room, paint booth, exhaust, make-up air and utility work around these finishing operations.
Discuss your installationModule Frames After Fit-Up
Fabricated frames often leave welding with braces, pipe supports, plates and nested surfaces that affect blasting and coating access. The finishing area should allow touch-up prep, masking, inspection and controlled movement into the booth or room.
Handling Heavy Skids and Racks
Large modules may require cranes, heavy carts, forklifts or temporary supports. Booth openings, blast room doors, staging lanes and floor space should be checked against the real handling equipment used in the shop.
Airflow Around Dense Structures
Module steel can block air movement and create pockets around braces and pipe supports. Exhaust placement, supply air and make-up air should be reviewed so the coating zone supports practical application access.
Utility and Trade Sequencing
Installation work can involve power, gas, compressed air, controls, ductwork, roof penetrations and fire protection coordination. Early sequencing helps reduce conflicts with cranes, weld cells, fabrication lanes and building services.
- Confirm maximum module dimensions and lift method.
- Identify where blasting, coating and inspection occur.
- Mark existing utilities that cross the proposed equipment area.
Frequently asked questions
What finishing equipment is common for offshore module fabrication?
Large paint booths, blast rooms, media reclaim systems, exhaust systems, dust collectors, make-up air units and paint mixing rooms are common.
Why is module geometry important for airflow?
Bracing, pipe supports and deep frames can interrupt air movement, so airflow should be considered with the actual workpiece shape.
What should be ready before a site visit?
Bring maximum module dimensions, coating process details, blast media information, equipment drawings when available, utility locations and photos of the proposed area.
How does relocation planning differ for large booths?
Relocation planning should consider panel size, fan and duct removal, utility disconnection, roof openings, rigging space and the route for moving large sections.
