The present invention relates to an arrangement structure of an engine casing of a drillship. The arrangement structure of an engine casing of a drillship is described as follows. A center engine casing among three engine casings is arranged in a position more forward than left and right side engine casings toward a bow. Hatches of thrusters are arranged in the spaces between the center engine casing and the left and right side engine casings to enable the optimal arrangement of the engine casings without interference with the thrusters. Therefore, the present invention reduces the construction costs of the drillship by remarkably reducing the whole longitudinal length of the drillship compared with a conventional ship, reduces drilling costs by reducing the resistance of a hull during dynamic positioning operation, and maximally expands an open deck space by efficiently using the space of the hull.
본 발명은 드릴쉽의 엔진 케이싱 배치구조에 관한 것으로, 3개의 엔진 케이싱 중에서 센터 엔진 케이싱이 좌우 사이드 엔진 케이싱보다 선수방향으로 더 이동된 상태로 배치되고, 센터 엔진 케이싱과 좌우 사이드 엔진 케이싱 사이의 공간에 스러스터의 해치가 배치됨으로써, 스러스터와의 간섭없이 엔진 케이싱의 최적 배치가 가능하여 드릴쉽의 선체 길이방향의 전장(全長)이 종전에 비해서 대폭 단축되어 드릴쉽 건조비용을 절감할 수 있고, 동적 위치유지중 선체의 저항이 감소하여 시추비용을 절감할 수 있으며, 선체의 공간활용이 효율적이어서 오픈 데크 공간을 최대로 확장할 수 있는 효과가 있다.
