본 발명은 선체의 데크 하부에 형성되는 라이저 적재영역 및, 라이저 적재영역에 설치되며, 선택된 라이저를 상기 라이저 적재영역과 상기 데크의 상부로 승강시키기 위한 홀더가 구비된 승강유닛을 포함하며, 홀더의 하부에 이격된 상태로 함께 승강 가능하게 설치되며, 라이저 적재영역과 데크의 상부 연결위치로 승강 가능하게 설치되는 리프트레일과, 데크에 수평하게 설치되어 이송경로를 형성하며, 리프트레일이 연결위치로 상승시 리프트레일과 수평하게 연결되는 이송레일 및, 이송레일을 따라 이동 가능하게 안착되며, 리프트레일이 연결위치로 상승 위치되는 경우, 리프트레일로 이동되어 홀더에 장착된 라이저가 상부에 안착된 상태로 타측의 작업위치로 이동되는 캣워크를 포함한다.

    A riser transfer apparatus of the present invention includes: a riser loading area formed in a lower portion of a deck of a hull; and a lifting unit installed in the riser loading area and having a holder for lifting a selected riser to the riser loading area and an upper portion of the deck. The riser transfer apparatus also includes: a lift rail installed in a lower portion of the holder to be liftable with the holder in a state of being spaced apart from the holder and installed to be liftable to a connecting position of the riser loading area and the upper portion of the deck; a transfer rail horizontally installed in the deck to form a transfer path and horizontally connected to the lift rail when the lift rail is lifted to the connecting position; and a catwalk mounted to be movable along the transfer rail and moved to the lift rail to be moved to an operation position of the other side in a state in which the riser mounted on the holder is mounted on the upper portion when the lift rail is lifted and positioned into the connecting position. Therefore, the riser transfer apparatus can simplify a riser transfer structure.
