一前言 1981年5月9日至22日,在我国南海三亚外港利用半潜式钻井平台《南海二号》配属的氦氧饱和潜水设备,成功地进行了302米氦氧饱和潜水模拟实验。这次实验的成功,标志着我国的潜水技术有了新的重大突破,对我国海洋事业的发展有重大意义。氦氧饱和潜水技术是近海工程和海上石油勘探开发中不可缺少的技术。饱和潜水中,利用工程技术设备对人体居住的舱室环境进行精确的控制是保证饱和潜水安全至关紧要的技术。饱和潜水的舱室环境控制主要有三个方面:舱室压力控制;舱室气体成分控制和舱室温湿度控制。
Foreword From May 9 to May 22, 1981, a successful trial of 302-meter Helioxed Diving simulation was carried out in the Outer Harbor of Sanya, South China Sea, using the helium-oxygen saturation diving equipment that is part of the “Nanhai II” semi-submersible drilling platform. The success of this experiment marks a major new breakthrough in diving technology in our country and is of great significance to the development of China’s marine undertakings. Heliox-saturation diving technology is an indispensable technology in offshore engineering and offshore oil exploration and development. Saturated diving, the use of engineering and technical equipment for living in the cabin environment for accurate control is to ensure the safety of saturated diving is crucial technology. Saturated diving cabin environment control has three main aspects: cabin pressure control; cabin gas composition control and cabin temperature and humidity control.
