PROBLEM TO BE SOLVED: To provide a mooring system of an offshore structure group loaded with a wind power generator and the like provides a mooring system of an offshore structure group where the offshore structure moves even when a partial fracture of a mooring cable that moors an offshore structure, but continues to be moored with a remaining mooring cable group to enable the offshore structure to be avoided colliding with another offshore and is capable of being moored safely at an offshore installation location with no excessive increase in strength of a mooring cable in the mooring direction of the same, and a mooring method of an offshore structure group.SOLUTION: At least one offshore structure 10A out of an offshore structure group configured of a plurality of offshore structures 10A is moored by using mooring cables 20A,20B arranged in three or more and eight or less directions to engage the mooring cables 20A,20B in the respective directions with separate mooring stems 30, and at least one mooring stem 30 engages the mooring cables 20A,20B connected respectively to three or more and eight or less offshore structures 10A out of the offshore structure group.SELECTED DRAWING: Figure 2
【課題】風力発電装置等を搭載した洋上構造物群の係留システムにおいて、例え洋上構造物を係留する係留索の一部の破断が生じても、その洋上構造物は移動するが、その洋上構造物を残りの係留索群により係留し続けて、その洋上構造物が他の洋上構造物と衝突することを回避できて、その係留方向の係留索の強度を過度に高くすることなく、安全に洋上設置場所に係留できる洋上構造物群の係留システム、及び洋上構造物群の係留方法を提供する。【解決手段】複数の洋上構造物10Aで構成される洋上構造物群の内で少なくとも1つの洋上構造物10Aを3方向以上8方向以下の方向に配置される係留索20A,20Bを用いて、それぞれの方向の係留索20A,20Bを別々の係留基部30に係止して係留すると共に、少なくとも1つの係留基部30が、洋上構造物群の内の3基以上8基以下の洋上構造物10Aにそれぞれが接続する係留索20A,20Bを係止する。【選択図】図2
