Modular Skid & Frame Detailing

Modular Skid & Frame Detailing
This modular skid project included complete structural steel detailing for multiple preassembled skids used in oil and gas applications. Fab Steel handled 3D modeling, connection detailing, and lifting lug design as per offshore standards (DNV-ST-N0O1).
The challenge was integrating equipment weights, load paths, and access platforms into one unified structural package without fabrication conflicts.
Key Deliverables
We deliver detailed 3D models and fabrication drawings for modular skids and frames, complete with transport, lifting, and installation plans optimized for off-site construction.
-
3D model of modular skid frames
-
Lifting point verification and drawings
-
Connection detailing per DNV/NORSOK
-
Shop and assembly drawings with bolt lists
-
Access platform and handrail detailing
-
MTOs and part marking plans

Our Working Process
Skid detailing blends mechanical and structural accuracy. Our team followed a staged approach, beginning with layout locking, followed by lifting point validation and component framing.
Model Development
Created a Steel model with accurate equipment placeholders and platform interfaces.
Drawing & Detailing
Issued lifting frame details, connection drawings, and MTOs based on shipping constraints.
Coordination & Optimization
Clash detection and layout verification were done for skid footprint and access clearances.
Result & Impact
The skid units were fabricated in parallel with equipment and delivered ready for offshore lifting without modification. Our clear marking plans and bolt layouts allowed seamless bolting and loading onto trailers and vessels. The project was signed off in a single QA cycle.
