To provide a rotation measuring device and a rotation measuring method capable of quantitatively measuring the twisting of an underwater cable.SOLUTION: A rotation measuring device 100 comprises a pressure-resistant vessel 110, a fixture 170 to fix the pressure-resistant vessel to an underwater cable 30, and a measurable sensor 120 built in the pressure-resistant vessel and to measure the rotation measurement value which is the state quantity related to the rotation of the pressure-resistant vessel, where the pressure-resistant vessel can keep the inside thereof watertight without deformation at the water depth reached by the tip of the underwater cable the base end of which is attached to a ship and the tip of which is suspended in the water.SELECTED DRAWING: Figure 2

    【課題】水中ケーブルの捻じりを定量的に計測できる回転計測装置および回転計測方法を提供する。【解決手段】回転計測装置100は、基端部が船舶に取り付けられ且つ先端部が水中に垂下される水中ケーブル30の先端部が到達する水深において、変形せずに内部を水密に保持可能な耐圧容器110と、水中ケーブルに耐圧容器を固定する固定具170と、耐圧容器に内蔵され、耐圧容器の回転に係る状態量である回転計測値を計測可能なセンサ120を備える。【選択図】図2
