Summary
Sets criteria for offshore helicopter landing areas on installations and vessels, alongside wind-turbine winching arrangements. Covers structural loading, obstacle protection, surface friction testing, lighting, motion monitoring, meteorological reporting, rescue and fire-fighting, fuel-system design and maintenance, and passenger preparation. The January 2026 amendment introduces arrangements for temporary safety-critical equipment unserviceability.
