Seasnake is a OceanERA-NET project aiming for developing dynamic Cables for ocean energy. The project contains design and production of cables and environmental friendly anti-fouling, lab and offshore testing.

The main goal of the SEASNAKE project is to provide a step change in the overall performance of a medium voltage cable system, while ensuring that they are highly reliable and lower the risks of ocean energy installations.

The  Specific Objectives of Seasnake are:

  • Objective 1: To increase the economic viability of Ocean energy cable systems by reducing the Levelised Cost of Electricity (LCOE) at least 20% of the dynamic cable subsystem, by CapEx and OpEx reduction 
  • Objective 2: To proof that 95% availability can be achieved with an improved design for reliability, maintainability and survivability of all cable sub-systems, validated in a relevant environment, reaching TRL7
  • Objective 3: De-risk, minimise and optimise offshore operations related to the dynamic cable, to achieve lower annual OpEx, thereby reducing LCOE for a WEC system further.
  • Objective 4: Demonstration of dynamic cable solutions
  • Objective 5: Minimise environmental impact

Project partners are NKT cables, I-Tech, MWA Coating, Waves4Power, Corpower, OceanHarvesting Technologies, Chalmers University of Technology and RISE Research Institutes of Sweden from Sweden, as well as Université Gustave Eiffel (former IFSTTAR) from France, WaveC from Portugal, and Wave-Venture from Ireland.
