DDMS deep draft column platform

一种ddms深吃水立柱平台

Abstract

本发明公开了一种DDMS深吃水立柱平台,属于海洋工程及船舶工程技术领域,适用于深海海域的油气钻探与生产。其特征是平台由4个深吃水的立柱、一个中央井立柱、垂荡板、横向浮桥、软舱、系泊系统、立管系统以及平台上体组成,4个深吃水的立柱位于平台横截面的4个角点,中央井立柱位于横截面中心,K型梁位于硬舱顶部连接立柱和中央井,垂荡板与平台硬舱直接集成,水平安装在立柱上,横向浮桥在硬舱底部连接各立柱,平台底部配置大体积的软舱并充满压载物。本发明的有益效果是:平台的建造难度与成本较低;中央井结构使立管得到保护;更大的整体设计弹性及平台上体使用空间;水动力性能得到提高,具有良好的运动性能;支持干式采油树的使用;适用于多种不同的海域及海况条件。
The invention discloses a DDMS heavy draught upright post platform, which belongs to the technical field of ocean engineering and ship engineering, and is applicable to oil gas drilling and producing of an abyssal sea area. The upright post platform is characterized by consisting of four heavy draught upright posts, an upright post of a center well, a heave plate, a transverse pontoon bridge, a soft cabin, an anchoring system, a riser system and a platform upper part, wherein the four heave draught upright posts are arranged on four angular points of a cross section of the platform; the upright post of the center well is arranged in the center of the cross section; a K-shaped beam is arranged on the top of a hard cabin to connect the upright posts and the center well; the heave plate and the hard cabin of the platform are directly integrated into a whole, and are horizontally arranged on the upright posts; the transverse pontoon bridge is arranged on the bottom of the hard cabin to connect each upright post; and the soft cabin in large volume is arranged on the bottom of the platform and is filled with ballast weight. The platform has the advantages that building difficulty and cost of the platform are lower; the structure of the center well makes the upright posts protected; elasticity of global design and use space of the platform upper part are larger; hydrodynamic performance can be improved, so the platform has excellent motion performance; application of a dry-type tree is supported; and the platform is applicable to various conditions of different sea areas and sea conditions.
