To provide a submarine cable or the like which is coupled to a floating body type offshore wind power generation system.SOLUTION: A submarine cable 1 with a buoyancy body comprises: a submarine cable 3 extending from a sea bottom S1 through submarine S2, and being coupled to a floating body type offshore wind power generation facility provided on a floating state on sea S3; and a first buoyancy body 4 fitted to a buoyancy body attachment part 3a of the submarine cable 3. The buoyancy body attachment part 3a is formed into an extension shape of being curved in a protrusion state toward a sea level S3 by an action of buoyancy F by the first buoyancy body 4, the submarine cable 3 is configured to maintain a floating state in the submarine S2 without contacting the sea bottom S1. The submarine cable 3 further comprises precipitation prevention means 6 for preventing precipitation of the submarine cable 3 and contacting the sea bottom S1 following increase of a weight on the buoyancy body attachment part 3a caused by adhesion of a marine organism 5 to a surface of the first buoyancy body 4.SELECTED DRAWING: Figure 1

    【課題】本発明の目的は、浮体式洋上風力発電設備に連結される海中ケーブル等を提供する。【解決手段】本発明の浮力体付き海中ケーブル1は、海底S1から海中S2を通って延在し、海上S3に浮かんだ状態で位置する浮体式洋上風力発電設備に連結される海中ケーブル3と、海中ケーブル3の浮力体被装着部分3aに装着された第1浮力体4とを備え、浮力体被装着部分3aが、第1浮力体4による浮力Fの作用によって、海面S3に向かって凸状に湾曲した延在形状を有し、かつ海中ケーブル3が、海底S1に接触せずに海中S2に浮かんだ状態を維持できるように構成され、海中ケーブル3は、海洋生物5が第1浮力体4の表面に付着することによる浮力体被装着部分3aにおける重量増加に伴って、海中ケーブル3が沈降して海底S1に接触するのを防止する沈降防止手段6をさらに備えている。【選択図】図1
