METHOD AND INSTALLATION FOR LAYING MOORING CHAIN
PROBLEM TO BE SOLVED: To provide a method for laying a mooring chain which suppresses a construction cost by shortening an operation time and is preferable in safety and quality respects.SOLUTION: A self-navigation type crane ship 7 which has self-navigation ability and can load a plurality of mooring chains 3 is navigated to a construction sea area by oneself, thereafter, the self-navigation type crane ship 7 is held on a prescribed position in the construction sea area by a fixed point holding device 15, an anchor 4 of the mooring chain 3 is lifted by a crane 8 of the self-navigation type crane ship 7 and is lowered into sea, and, at the same time, the mooring chain 3 is sent out into sea by means of a private windlass 23 provided on the self-navigation type crane ship 7. Thereby, a construction cost can be suppressed by shortening an operation time and more preferable results than heretofore can be obtained in safety and quality respects.SELECTED DRAWING: Figure 3
【課題】作業時間を短縮することで施工費を抑え、安全面及び品質面において良好な係留チェーンの敷設方法を提供する。【解決手段】自航能力を有して、複数の係留チェーン３を積載できる自航式起重機船７を自力で施工海域まで航行させた後、定点保持装置１５により当該自航式起重機船７を施工海域の所定位置に保持して、係留チェーン３のアンカー４を自航式起重機船７のクレーン８にて吊り上げて、海中に吊り下ろしながら、係留チェーン３を当該自航式起重機船７に備えた専用のウインドラス２３にて海中に向かって送り出すようにしている。これにより、作業時間を短縮することで、施工費を抑えることができ、安全面及び品質面において従来よりも良好となる。【選択図】図３
