巨大且つ複雑な機構となって非現実的なものである。Further, in the chain anchor mooring system, a large number of mooring lines must be arranged all around the floating structure, and these mooring lines hinder the approach and berthing of the ship, and furthermore, a large floating body When installing structures, it is indispensable to install breakwaters such as floating breakwaters in order to eliminate and stabilize the effects of waves as much as possible.However, both floating breakwaters and floating structures must be installed. When mooring with mooring lines, the distance between the two must be set so that the mooring lines do not interfere with each other. Since this distance increases according to the water depth (length of the mooring line), the installation interval between both becomes large. There is a problem that it becomes impossible to install a floating structure in an effective wave-dissipating region by a floating breakwater. If the floating breakwater and the floating structure are connected via a mechanical joint mechanism, they can be installed close to each other, but if the relative displacement movement between them increases during stormy weather such as a typhoon, there is a risk of damage. There is a huge and complicated mechanism to prevent it, which is impractical.
