The invention discloses an offshore telescopic floating drilling platform and a drilling ship, and relates to the technical field of drilling platform engineering, and the offshore telescopic floating drilling platform comprises a sliding device arranged on a ship body; the sliding platform is arranged on the sliding device in a sliding mode and used for installing drilling equipment, the sliding platform can slide on the sliding device in the transverse direction of the ship body till one end extends out of the ship body, and a reserved opening is formed in the end, extending out of the ship body, of the sliding platform and used for lowering a drill rod; and the driving device is used for driving the sliding platform to slide on the sliding device in the transverse direction of the ship body and enabling the reserved opening to extend out of the ship body. When rapid evacuation is needed in emergency, the drill rod is disconnected, part of the drill rod is left in situ, the sliding platform is retracted to the ship body through the sliding device, the drill rod left in situ is separated from the area of the sliding platform from the reserved opening, rapid evacuation can be completed, the evacuation efficiency is high, the safety performance is good, and the problems that in the prior art, evacuation efficiency is low, and the service life is short are solved. And safety accidents may occur.
本发明公开了一种海上伸缩式浮动钻探平台及钻探船,涉及钻探平台工程技术领域,包括滑动装置,其设置在船体上;滑动平台,其可滑动地设于滑动装置上,用于安装钻探设备,滑动平台可在滑动装置上沿船体的横向方向滑动至一端伸出船体,滑动平台伸出船体的一端设有预留开口,预留开口用于下放钻杆;驱动装置,其用于驱动滑动平台在滑动装置上沿船体的横向方向滑动,并使预留开口伸出船体。当遇到紧急情况需要快速撤离时,断开钻杆,部分钻杆留在原地,滑动平台通过滑动装置收回至船体上,留在原地的钻杆从预留开口脱离滑动平台的区域,即可完成快速撤离,撤离效率高,安全性能好,解决了现有技术中存在撤离效率低,进而可能会发生安全事故的问题。
