In 2024, slips and trips at the same height accounted for 22% of lost-workday cases reported by IOGP member companies (206 cases) — the single largest cause of lost-time injuries offshore. This is the short guide to choosing surfaces that stay safe.

Why offshore walkways fail

Salt spray, hydraulic oil, marine growth, condensation, rain and platform motion leave decks wet, slick and unpredictable — 24/7. A surface that passes a dry-floor test can fail within one shift.

The standards to know

• OSHA 1910 Subpart D & ANSI A1264.1 — US walking-working surface requirements
• EN ISO 14122 — access walkways, platforms and stairs in Europe
• DIN 51130 — the R9–R13 slip-rating scale; specify R12+ for wet walkways, R13 for oily zones
• ISO 24681:2023 — FRP grating standard with dedicated skid-resistance testing

30-second selection checklist

R12 minimum slip class → loads & spans → fire-retardant, UV-inhibited resin → non-sparking for classified zones → third-party test reports → compare 20-year lifecycle cost, not unit price.

Work with a certified supplier

Endura manufactures pultruded and molded FRP grating for offshore platforms, holds DNV, ISO and SGS certifications, and has supplied 2,000+ sets of platform grating for offshore wind projects, with engineering support and test documentation included.

Bottom line: molded-in-grit FRP grating is the low-maintenance, corrosion-proof way to keep R12–R13 traction underfoot in salt, spray and oil — specify it, verify it, and the deck holds.
