饱和潜水技术在深水海底管线膨胀弯安装中的应用

海洋石油的开发逐渐向更深水域发展，饱和潜水技术由于作业水深较深，持续作业时间长的特点正在被广泛采用，并将得到更大的发展。饱和潜水技术是人类对于潜水技术的又一个突破。在海管膨胀弯安装中，由于需要进行复杂的水下操作，饱和潜水技术被普遍用于海管膨胀弯的安装中。本文通过以平湖二期八角亭工程项目海管膨胀弯安装的实倒，对饱和潜水技术进行简单介绍，并对膨胀弯安装中饱和潜水技术的应用进行重点叙述，对未来其他深水使用饱和潜水技术进行海管膨胀弯安装可以有借鉴作用。

The Application of the Saturation Diving Technology in the Installation of the Deep Subsea Pipeline Spool Pieces

The development ofoffshore exploitation is beingsped upin deeper water. The Saturation DivingTechnology is beingextensive used because of the deeper operation depth and the longer continued operation hours and will be developed filrther. The Satttrafion DivingTechnology is a b reakthrou gh at diving techn o logy for h urn an. The S a turation D ivin g T echn o logyis b ein g used for the I nstaUatio n o fth e Sub-sea Pipeline Spool Pieces, in which there is too much complicated operation needed underwater. Based on Spool Pieces InstaUation of Ping Hu II BaJiao TingProject; the SaturationDivingTechnologyisintroducedand the application of the Saturation DivingTechnologyin the I nstaUationofthe S ub-seaPipeline Spool Pieces as animportant pointis specified. It canbe usedthe experience for reference projectin future.
