新型无桩多井口平台

A NEW PILELESS MULTI-WELLHEAD PLATFORM

渤海工程设计公司研究开发的新型无桩多井口平台由四根大直径立柱及连接立柱的桁架组成,采用了导流下沉式基础。它的安装方法不同于一般平台,它可用充气自浮的方式拖运到安装现场,其基础可自行沉到泥面以下的指定深度。为了证实平台在气封状态下的水动力特性,在中国船舶科学研究中心做了各种海况条件下的一系列模型试验。结果表明:这种平台性能良好,平台用钢量少,安装速度快,可节省部分工程投资。

The new pileless multi- wellhead platform studied and developed by BEDC is composed of four columns of large diameter and the truss connected to the columns . The installation of this kind of platform, its foundation setting through guiding water flow,is different from that of the common ones in that it is towed to the construction site with inflation and self-buoying , whose foundation can fall by itself to the designated depth below the silt. A series of model tests have been made in various sea conditions in the Research Centre of Ship Science of China, and show that this kind of platform is of good properties,constructed with less quantity of steel ,installed faster,and can save a part of the engineering cost.
