对于深水半潜式钻井平台，空调系统的配置直接影响平台员工的健康和平台电器的安全操作。针对中国南海某深水半潜式钻井平台的空调系统配置，比较了同类型半潜式钻井平台，调查和分析了中国南海的海域环境。综合考虑深水半潜式钻井平台的空间布置、作业海域环境以及NORSOK标准的相关要求，完成了本平台空调系统配置的选型。

The air-conditioning system of deepwater semi-submersible drilling rig directly affects the health of employees and the operation safety of electrical equipment on the platform. For the air-conditioning system equipment selection of a semi-submersible drilling rig in the South China Sea, comparison of the same type of semi-submersible drilling rigs is carried out, and the environmental conditions of the South China Sea are investigated and analyzed. Considering the spatial arrangement of deepwater semi-submersible drilling rig, the environmental conditions and the requirements on vibration, noise and comfortableness in NORSOK standards, the air-conditioning system equipment selection of this platform is accomplished.
