If you’ve worked around offshore or rooftop pads, you already know the unsung hero is the net on the edge. Helideck Perimeter Safety Nets are the last line of defense when wind, rotor wash, and human error line up in exactly the wrong way. I’ve watched crews step out on stormy days; the net quiets everyone’s nerves—and not just symbolically.
Offshore activity is back, hospital heliports are busier, and certification audits are getting tighter. Trends we’re seeing: stainless wire-rope meshes replacing older polypropylene in harsh marine zones, more factory drop-testing, and modular brackets that simplify retrofits. To be honest, procurement teams care about lifecycle cost and audit-ready paperwork as much as mesh size these days.
Perimeter Safety Netting is the surrounded structure on a helicopter landing deck that helps prevent tools and people from falling. Origin matters: this system is engineered and assembled in the industrial zone, south of Anping Town, Hengshui, Hebei, China—an area with a serious mesh-making pedigree. Many customers say the kits feel “overbuilt,” which, frankly, is what you want when the wind howls.
| Net width (CAP 437 guidance) | ≈ 1.5 m outboard, inner edge flush with deck |
| Mesh aperture | ≈ 80–100 mm (knotless preferred to reduce injury) |
| Rope/wire | UV-stabilized PP/PE rope (≥ Ø10 mm) or 304/316/316L wire rope (Ø3–4 mm) |
| Frame/brackets | Marine-grade stainless steel with hot-dip galvanized options |
| System load tests | Factory drop test with 100 kg bag from ≈1.2 m; strand tensile ≈1.0–1.6 kN (real-world use may vary) |
| Service life | ≈ 8–15 years depending on UV/salt exposure and inspections |
| Certifications/support | Designed to align with CAP 437, ICAO Annex 14 Vol II, IMO guidance; project-specific ITP/QC docs |
Offshore platforms, FPSOs, drillships, coast guard cutters, hospital heliports, and high-rise rooftop pads. Advantages? Better edge protection, compliance peace of mind, and—surprisingly—less visual clutter with modern wire-mesh styles.
| Vendor | Material scope | Lead time | Cert/docs | Notes |
|---|---|---|---|---|
| H&F PetroMesh (Anping) | PP/PE rope & 304/316/316L wire-rope; full bracket kits | ≈ 2–5 weeks | ITP, 3.1 certs, factory drop-test | Custom radii; cost-efficient |
| Vendor A (EU) | Primarily stainless wire mesh | ≈ 6–8 weeks | CE traceability set | Premium pricing |
| Vendor B (US) | Poly rope systems | ≈ 4–6 weeks | Test reports on request | Fast retrofit hardware |
Bracket geometry for odd beam spacing, mesh aperture for glove safety, anti-spark covers near fuel points, color-coding for zones, and removable sections for gangways. Many crews prefer Helideck Perimeter Safety Nets with a subtle 10–15° outboard dip—better energy absorption, less bounce-back.
North Sea operator: “Install took a day less than planned; brackets lined up first time.” A hospital facilities team told me the newer wire-rope Helideck Perimeter Safety Nets felt sturdier in winter icing, with fewer post-flight snags on medical gear.
Designs are aligned with CAP 437 guidance on width, mesh, and layout, ICAO Annex 14 Vol II provisions, and IMO recommendations for shipboard helidecks. Final acceptance should include a visual inspection, torque verification, and a controlled drop test where permitted by the operator’s safety case.
