🔍 Key Concepts

• Offshore drilling unit helicopter deck lighting requirements in 46 CFR (MODU regulations) • Purpose of perimeter (deck edge) lights for helicopters at night or in low visibility • Typical aviation safety color conventions: what different colors usually indicate (e.g., caution, obstruction, safe landing area)

💭 Think About

• Think about which two colors are most commonly used in both marine and aviation contexts to mark safe operating areas and boundaries rather than hazards only. • Ask yourself: which color pair would give high contrast and good visibility from the air at night without being confused with emergency or obstruction-only lighting? • Consider which color combination is most consistent with standard helicopter landing pad markings you may have seen on offshore platforms, ships, or hospital roofs.

✅ Before You Answer

• Verify in the relevant 46 CFR part for MODUs and helicopter facilities what colors are specified for deck perimeter lights. • Check which of the listed colors are typically associated with hazard/obstruction versus guidance/operational boundaries in both maritime and aviation lighting. • Confirm that the chosen color pair would be clearly distinguishable from navigation lights and from emergency signal lights to avoid confusion.
