The present invention relates to a lifting device for a derrick structure and a drillship having the same and, more specifically, to a lifting device for a derrick structure, which improves stability by lowering the center of mass of a hull using a lifting unit for lifting a derrick structure in a moon pool, and remarkably reduces work time required for assembling and disassembling a drill pipe when drilling the deep sea by not requiring a work for vertically positioning the drill pipe during a drilling work as the drill pipe is vertically positioned in a drill pipe racking device before the drilling work, and a drillship having the same. The lifting device for a derrick structure for a drilling work, according to the present invention, comprises a lifting unit for lifting the derrick structure in the moon pool.

    본 발명은 데릭 구조물의 승강 장치 및 이를 포함하는 시추선에 관한 것으로서, 더욱 구체적으로는 데릭 구조물을 문풀에서 승강하기 위한 승강 유닛을 마련하여 선체의 무게중심을 낮춰 안정성을 높이고, 시추 작업 이전에 드릴 파이프 랙킹 장치에 드릴 파이프를 미리 세워 놓을 수 있어 시추 작업 시 드릴 파이프를 세우는 작업이 생략됨으로써 심해 시추시 드릴 파이프를 조립 및 해체하는 작업 시간을 현저히 줄일 수 있는 데릭 구조물의 승강 장치 및 이를 포함하는 시추선에 관한 것이다. 본 발명에 따른 시추 작업을 위한 데릭 구조물에 있어서, 상기 데릭 구조물을 문풀에서 승강하기 위한 승강 유닛을 포함하는, 데릭 구조물의 승강 장치를 포함한다.
