Efforts to achieve carbon neutrality by 2050 are gaining momentum, and the transformation of the energy structure is attracting attention. In particular, the government has set a future goal of significantly increasing the amount of power generated by offshore wind power generation, which is driving demand for submarine power cables. In addition, in order to make renewable energy the main power source and strengthen the power network, a master plan for a wide-area interconnection system using DC submarine cables has been presented, and the importance of submarine power cables is increasing more than ever. We are developing technologies to meet these demands, and in this paper we describe the development of a dynamic power cable system for TLP (Tension Leg Platform) floating offshore wind power generation and the development of a deepwater submarine cable.
