“探海1号”大陆架科学钻探平台的设计与应用

Design and Application of “Tanhai No. 1”Platform for the Continental Shelf Scientific Drilling

摘要:

为适用于水深在10 m以深30 m以浅距离海岸带上百千米的近海大陆架固体矿产勘探要求，同时满足中国地质调查局“中国东部海区科学钻探工程施工”项目CSDP-02井的钻探施工需要，根据以往简易海上平台研制的经验及基础，借鉴大型石油钻井平台的设计理念，研制出了一款多功能浅海钻探平台——“探海1号”。实际应用表明，效果良好。该平台甲板结构采用模块错缝搭接组合的创新形式以及可靠的桩体系统。介绍了该平台的方案设计、生产制造、海上安装以及应用效果情况。

Abstract:

In order to meet the requirements of solid mineral exploration at the depth of 10m to 30m in offshore of the continental shelf over 100km from the coast belt, and also meet the requirements of CSDP-02 well drilling construction of China Geological Survey “China East Sea Area of Scientific Drilling Project Construction”, according to the past experience and the basis of the research on simple offshore platform, drawing lessons from design concept of large oil drilling platform, a multifunctional shallow sea drilling platform “Tanhai No. 1” was developed. The practical application shows good effects. The platform deck structure adopts the innovative form of module staggered joints and reliable pile system. The scheme design, manufacturing, offshore installation and the application effects of the platform are introduced.
