계선삭 장력 제어 시스템(1)은, 계선삭이 감겨지는 드럼(3)과, 드럼(3)을 회전시키는 모터(22), 밴드 브레이크(4) 및 클러치(24)를 제어하는 제어 장치(7)를 포함한다. 밴드 브레이크(4)에는, 밴드 장력을 계측하는 로드셀(40)이 내장되어 있다. 제어 장치(7)는, 계선시에, 로드셀(40)에서 계측된 밴드 장력에 기초하여 계선삭의 장력을 산출하고, 산출한 계선삭의 장력이 설정값을 상회하면, 밴드 브레이크(4)를 개방 상태로 전환하여 계선삭을 드럼(3)으로부터 권출하고, 그 후에 클러치(24)를 맞물림 상태로 전환하는 동시에 모터(22)를 구동하여 계선삭을 드럼(3)에 권취한다. A mooring line tension control system (1) includes: a drum (3) around which a mooring line is wound; and control circuitry (7) that controls a motor (22), a band brake (4), and a clutch (24). The motor (22) rotates the drum (3). A load cell (40) that measures band tension is incorporated in the band brake (4). In a ship mooring state, the control circuitry (7) calculates tension of the mooring line based on the band tension measured by the load cell (40), and in a case where the calculated tension of the mooring line is greater than a setting value, the control circuitry (7) switches the band brake 4 to a released state to unwind the mooring line from the drum (3), and thereafter switches the clutch (24) to an engaged state and drives the motor (22) to wind the mooring line around the drum (3).
