海上自升式工程地质勘察平台的设计与应用

Design and application of the marine jack-up platform for geo-investigation

漂浮式工作平台受天气、波浪、潮汐等自然因素的影响较大,需根据天气窗口期进行作业施工,对工期紧、需较长作业周期、技术要求高的项目并不适用。本文设计的自升式工程地质勘察平台,既具备了浮式工作平台、改装驳船等施工平台的优点,又因其具备自升功能,施工期间甲板离开海平面可以最大程度避免气象、环境因素的影响,有效延长施工窗口期,提高工作效率,同时稳定的海上作业平台,极大地提高了数据参数获取的准确度。

The floating work platform is greatly affected by weather,wave,tide and other natural factors;thus,construction needs to be done according to the weather window period.It is not suitable for projects with the tight construction period,long operation period and high technical requirements.The jack-up platform designed in this paper not only has the advantages of floating working platforms,refitted barges and other construction platforms,but also has the self-elevation function by which the deck can leave the sea level to avoid the influence of meteorological and environmental factors to the greatest extent,effectively extend the construction window period,and improve work efficiency during the construction period;at the same time,the stable marine work platform greatly improves the accuracy of data parameter acquisition.
