Oil & Gas / Offshore
Why Oil & Gas / Offshore Needs FRP
Offshore platforms fight a triple enemy: saltwater spray, H₂S and extreme weight constraints. Every kilogram of topside steel costs money to install and maintain. Pultruded FRP grating is up to 75% lighter than steel and immune to saltwater corrosion.- Topside weight reduction is critical for offshore design
- Saltwater and H₂S corrosion of steel decks
- Electrically live areas needing non-conductive access
- Remote locations demanding zero-maintenance materials
ZeAllgrate Solutions for Oil & Gas / Offshore
ZeAllgrate pultruded grating and handrail systems deliver offshore-grade performance: 70% glass content for stiffness, fire-retardant resin options, and complete systems that bolt together without welding.
Typical Applications

Technical Specifications & Compliance
Application-specific engineering reference for Oil & Gas / Offshore — corrosion rating, load criteria, governing codes and the recommended ZeAllgrate configuration. Use this as the specification starting point; final design must be verified against certified load/span charts and the project's governing codes.
| Parameter | Specification for Oil & Gas / Offshore |
|---|---|
| Corrosion Level | Severe Saltwater spray, H₂S / sour service, cathodic disbondment risk and constant UV on topside steel. |
| Typical Load Requirements | Topside pedestrian/deck 5 kN/m² (≈105 psf) minimum per offshore practice; process module & drill-floor areas higher; helideck-adjacent access rated for maintenance loads; design also accounts for dynamic wave & wind motion. |
| Applicable Standards & Regulations | ABS (Offshore Installations), DNV-OS-C101 / DNV-RP-C202, USCG (33 CFR), IMO FTP Code (Parts 2–5 flame/smoke for accommodation), API RP 2A, NORSOK N-004, OSHA 1910.29, ISO 14122. |
| Recommended Resin System | ZeAll VE for saltwater/sour service; Phenolic (or ZeAll FR) for fire/smoke-critical accommodation & escape zones per IMO FTP; UV-stabilized topcoat for exposed areas. |
| Recommended Grating Type | Pultruded I6015/T5020 for long-span topside decks (weight-critical); Molded 38.1 mm for equipment platforms & non-slip working areas; tie-bar flush-top panels at 152 mm for gangways. |
Resin systems: ZeAll VE (vinyl ester — severe corrosion), ZeAll ISO (isophthalic polyester — general service), ZeAll FDA (food/potable grade), ZeAll FR (extra flame-retardant), Phenolic (fire/smoke-critical). Grating types: Molded (bi-directional), Pultruded (long-span), Mini-Mesh (fine openings), HLC (high-load capacity).
Offshore Service Requirements
| Requirement | ZeAllgrate Response |
|---|---|
| DNV / ABS class rules | Test reports, material data and batch traceability supplied |
| Fire performance | E84 / class-equivalent data for the grade |
| Seawater & chemical splash | Vinyl ester in splash zones; SS316 hardware |
| Non-conductive / non-sparking | Inherently non-metallic construction |
Specification Guidance
Offshore access systems are specified to class rules: confirm the fire performance data and laminate properties against the DNV/ABS requirement, design the decking to the class load and deflection criteria, and supply manufacturing QC and traceability so the installed product matches the certified data. Vinyl ester resists the splash-zone chemistry; SS316 clips and base plates carry the hardware. The case library documents offshore access and helideck walkway installations.
