In January, 1985, the mooring buoy for Kagoshima-Maru was newly installed in Yamagawa Harbor, Kagoshima Prefecture. The typhoons that approached or landed at Kagoshima Prefecture in the past were investigated, and Makurazaki Typhoon which is regarded as the typhoon of largest class in the postwar period was supposed, and as for the buoy, it was considered fundamentally that in the wind of maximum velocity 35m/s (on average for 10min), the ship can be moored safely by using only the chain (40mm) of the ship. Since then up to today, the mooring for harborage has been carried out at the time of 27 typhoons. Among them, the typhoon No. 13 on September 3, 1993 was the largest typhoon that the ship encountered at Yamagawa Harbor, and the maximum instantaneous wind velocity of 47.0m/s and the barometric pressure of 936.2 hPa were recorded, but the ship was able to be moored and shelter safely. It is considered that the structure and strength of the buoy were as planned and designed, and it was able to be proved.昭和60年1月鹿児島県山川港にかごしま丸係船浮標を新設した。浮標(ブイ)は過去に鹿児島県に接近上陸した台風を調べ,戦後最大級の台風とされる枕崎台風を想定し,最大風速35m/s(10分間平均)の風の中で,ブイに本船チェーン(40mm)だけで安全に係留出来ることを基本に考えた。以来今日まで,27個の台風時に係留避泊した。この中で平成5年9月3日の台風13号は本船が山川港で受けた最も大きな台風であり,最大瞬間風速47.0m/s,最低気圧936.2hPa.を記録したが安全に係留,避泊することが出来,ブイの構造,強度が計画設計通りであったことが証明出来たと考えられる。
