| Abstract: |
| Objective To make the helicopter of 7-2 drilling and production platform take off safely and control the probability of the helicopter's annual unavailability at lower than 10%. Methods The flow, temperature rise and turbulence distribution of the high temperature smoke over the helicopter deck were simulated under multi wind direction and wind speed based on fluent software. According to the safety principle of helicopter take-off and landing recommended by CAP43-7 standard, the annual impact probability of temperature rise and turbulence on takeoff and landing of helicopter was calculated. Results The probability value of the unavailability of the helicopter was obtained. It was 8% under working condition M1 and 9% under working condition M2. Conclusion The results provide a theoretical basis for the determination of the layout of the smoke pipe and the helicopter deck on the platform, and take a guiding role for the landing operation of the platform helicopter. |
