| 目的 对某海外海洋平台的直升机甲板上空直升机起降存在的风险进行分析。方法 对比分析国内外的标准规范，确定以CAP437为直升机起降的量化衡量指标，在此基础上利用数值模拟软件对影响直升机起降的两个主要因素，温度场和湍流场进行模拟分析。结果 无论是温升，还是湍流强度都不会对直升机的起降造成影响。结论 该海外海洋平台上直升机甲板的不可用概率为0。同时确认此平台柴油应急机的烟气排放，及空调冷凝单元气体排放位置设置合理。 |

| Objective To analyze the risk of take-off and landing of helicopters over the helicopter deck of an overseas marine platform. Methods The standards and codes at home and abroad were compared and analyzed to determine CAP437 as the quantitative measurement index for helicopter takeoff and landing. On this basis, CFD software was used to simulate the two main factors affecting helicopter takeoff and landing, temperature field and turbulent flow field. Results Neither the temperature rise nor the turbulence intensity would affect the take-off and landing of the helicopter. Conclusion The probability of unavailability of the helicopter deck on the offshore platform is zero. At the same time, it is confirmed that the discharge position of the exhaust of the diesel emergency engine and the gas discharge position of the air conditioning condensing unit are set properly. |
