The invention provides an offshore self-elevating platform for horizontal directional drilling construction, which comprises a directional drilling platform, a plurality of pile legs, a directional drilling system, an anchoring system and a dragging system, the directional drilling system, the anchoring system and the dragging system are all installed on the directional drilling platform. The main structure of the platform can be fixed above the sea surface by using a lifting system of the platform, and then directional drilling construction operation is carried out; and the device can also float on the sea surface like a traditional barge for directional drilling construction. And a more stable site which is not influenced by sea tide and can be reused is provided for offshore directional drilling construction. The problems that a hull of an existing directional drilling construction slab barge is not stable and is prone to being affected by sea water tide-up and tide-down, a fixed platform cannot be reused, and the building construction period is long are solved.
本发明提供了一种水平定向钻施工用的海上自升式平台,包括:定向钻平台、多个桩腿、定向钻系统、锚泊系统、拖曳系统,多个所述桩腿可升降地安装在所述定向钻平台上,所述定向钻系统、所述锚泊系统以及所述拖曳系统均安装在所述定向钻平台上。平台可以使用自带的升降系统将主结构固定在海面以上,再进行定向钻施工作业;也可以像传统的驳船一样漂浮在海面上进行定向钻施工。为海上定向钻施工提供一个更加稳固、不受海潮影响、可重复利用的场地。解决现有的定向钻施工平板驳船的船体不稳固、易受到海水潮起潮落影响,固定平台无法重复利用、建造施工周期长的问题。
