🛩️ Helideck Inspection Services – CAP 437 Compliance & Friction Testing
Introduction
Helideck safety is critical to offshore and onshore operations in the oil & gas, marine, and energy sectors. Ensuring that a helideck complies with international safety standards is essential to protect personnel and assets. One of the most widely recognized standards is CAP 437, issued by the UK Civil Aviation Authority (CAA), which defines requirements for helideck design, construction, maintenance, and performance — including surface friction.
At KHMERNDT CO., LTD, we provide professional helideck inspection services in compliance with CAP 437, including friction coefficient testing, visual inspection, and full helideck audit reporting for offshore platforms, FPSOs, and onshore facilities.
🔍 What is CAP 437?
CAP 437 – Standards for Offshore Helicopter Landing Areas outlines:
-
Structural integrity and helideck safety design
-
Lighting, markings, and fire-fighting equipment
-
Perimeter safety nets and obstacle-free zones
-
Surface condition and friction testing (Helideck Friction Testing)
-
Wind measurement systems
-
Compliance with touchdown/positioning markings, aiming circle, and obstacle evaluation
✅ Applicable for: Offshore oil & gas rigs, marine vessels, FPSOs, wind farms, hospital helipads, and heliports
⚙️ Friction Testing – Why It’s Important
Helideck surface friction must meet the minimum safety level to ensure rotorcraft can land and take off safely — particularly in wet or marine conditions.
Our Friction Testing service includes:
-
Testing with a Helideck Friction Tester (HFT) calibrated to CAP 437
-
Measuring Coefficient of Friction (CoF) at multiple test points
-
Identifying low-friction zones or surface deterioration
-
Providing pass/fail results with recommendations for resurfacing or coating
🧪 Per CAP 437, minimum average friction CoF is 0.65 for TLOF zone under dry/wet conditions.
