To provide a tension monitoring system of a mooring rope capable of detecting a mooring post side tension of a mooring rope without using an elongation rate sensor.SOLUTION: A tension monitoring system 1 of a mooring rope according to one embodiment monitors the tension of a mooring rope 10 which is hung on at least one mooring hardware 22 on a hull 21 and the tip of which is moored to a mooring post 31 of a fixed structure 3. The tension monitoring system of the mooring rope includes a mooring machine 4 including a drum with the mooring rope 10 wrapped around it and a control device 9. The control device 9 calculates a drum side tension P of the mooring rope 10, determines a tension attenuation factor R due to the mooring rope 10 being spanned over at least one mooring hardware 22, and calculates the mooring post side tension P0 of the mooring rope 10 by multiplying the drum side tension P by the tension attenuation factor R, or by dividing the drum side tension P by the tension attenuation factor R.SELECTED DRAWING: Figure 1

    【課題】伸長率センサを用いることなく係船索の係船柱側張力を検知することができる係船索張力監視システムを提供する。【解決手段】一実施形態に係る係船索張力監視システム1は、船体21上の少なくとも1つの係船金物22に掛け渡されるとともに先端が固定構造物3の係船柱31に係止された係船索10の張力を監視するものであり、係船索10が巻き付けられたドラムを含む係船機4と、制御装置9を含む。制御装置9は、係船索10のドラム側張力Pを算出するとともに、係船索10が少なくとも1つの係船金物22に掛け渡されることによる張力減衰率Rを決定し、ドラム側張力Pに張力減衰率Rを乗算するかドラム側張力Pを張力減衰率Rで除算することで係船索10の係船柱側張力P0を算出する。【選択図】図1
