Abstract
Mooring buoyes are widely employed to moor vessels in some isolated islands facing to the ocean. The impulsive tension induced by large waves may cause heavy damages to the mooring line and buoy. The application of a rubber-chain is proposed to reduce the impulsive tension. The effects of the rubber-chain are experimentally investigated. An approximate computation model for estimation of the impulsive tension on the mooring line is verified in the experimental results. The computational result for a buoy with a mooring line of 40m demonstrates that the employment of a rubber-chain only 10m long is effective to protect the occurence of the impulsive tensions.
