The present invention relates to a method for installing a mooring line for a floating offshore structure to moor an offshore structure in a floating state to a mooring spot. The method includes the following steps of: inserting and placing a first mooring chain a first mooring chain having a pair of first mooring chain marking buoys connected to both ends in a longitudinal direction through a first wire, and an anchor having an anchor position marking buoy connected through a second wire, on the seabed in the vicinity of a mooring spot; pulling up the first mooring chain from a mooring work vessel, and then, connecting and installing one longitudinal end of the first mooring chain to a mooring chain connection device arranged in the mooring work vessel; placing one longitudinal end of the second mooring chain connected to an offshore structure in the mooring work vessel while keeping the end connected to the mooring chain connection device; connecting a connection device marking buoy to the mooring chain connection device through a third wire, and then, inserting and placing the mooring chain connection device on the seabed between the offshore structure and the anchor; and adjusting the tension of the second mooring chain on the mooring work vessel, and then, dismantling the second mooring chain in the mooring work vessel. Therefore, the present invention is capable of quickly and easily mooring an offshore structure.

    본 발명은, 부유상태의 해양 구조물을 계류지점에 계류시키는 부유식 해양 구조물용 계류라인 설치방법에 있어서, 일측에는 길이방향 양단에 제1와이어를 통해 한 쌍의 제1계류체인 표시부이가 연결된 제1계류체인 및, 제2와이어를 통해 앵커위치 표시부이가 연결된 앵커를 계류지점 인근의 해저면에 투입 배치하는 단계, 계류작업 선박에서 제1계류체인을 끌어올린 후, 제1계류체인의 길이방향 일단을 계류작업 선박에 배치된 계류체인 연결장치에 연결 설치하는 단계, 해양 구조물에 연결된 제2계류체인의 길이방향 일단을 계류체인 연결장치에 연결상태로 계류작업 선박에 배치하는 단계, 계류체인 연결장치에 제3와이어를 통해 연결장치 표시부이를 연결한 후, 계류체인 연결장치를 해양 구조물과 앵커 사이의 해저면에 투입 배치하는 단계, 계류작업 선박에서 제2계류체인의 장력을 조절한 후, 계류작업 선박에서 제2계류체인을 해체하는 단계를 포함하는 부유식 해양 구조물용 계류라인 설치방법을 제공한다.
