PROBLEM TO BE SOLVED: To provide a mooring rope drum and a mooring structure body that can minimize a degree of influence on a worker on a deck as much as possible even if a mooring rope is broken.SOLUTION: A mooring rope drum 11 is provided on a deck of a mooring structure body so as to wind a mooring rope guided onto the ground through a fair-leader 15. A drum body 21 is driven by an independent driving source, different from a driving source of an anchor windlass, to rotate, and provided at a position closer to the fair-leader 15 than the anchor windlass. Flanges 22, 23 are fixed integrally to both axial ends of the drum body 21. The drum body 21 has its axial length so defined that a fleet angle A to the fair-leader 15 is, for example, larger than 0° and less than 10°. Assuming that a diameter d of the drum body 21 is 1, a diameter D of the flanges 22, 23 is larger than 3.8.SELECTED DRAWING: Figure 2

    【課題】係留索が破断したとしても甲板上の作業員に及ぼす影響度合いを極力小さく抑えることのできる係留索ドラムおよび係留構造体を提供する。【解決手段】係留索ドラム11は、係留構造体の甲板上に設けられ、フェアリーダー15を通って陸上に導かれる係留索を巻き取るために設けられる。ドラム本体21は、揚錨機の駆動源とは異なる独立した駆動源によって回転駆動され、揚錨機よりもフェアリーダー15に近い位置に設けられる。フランジ22、23は、ドラム本体21の軸方向の両端に一体的に固定される。ドラム本体21の軸方向長さは、フェアリーダー15に対するフリートアングルAが例えば0°より大きく、10°以下になるように定められる。ドラム本体21の直径dを1としたとき、フランジ22、23の直径Dは3.8よりも大きい。【選択図】図2
