Ta Ya succeeded in its submarine dynamic cable test, accelerating the development of wave power in Taiwan
2017/03/28
The ocean is a source of unlimited power, and Ta Ya has made good progress on the collaboration with the ITRI that began in 2014 for submarine dynamic cable development and sea trial: the company has successfully completed its open sea deployment of submarine dynamic cable off the shores of Keelung. The outcomes of the test will accelerate the development of wave power related technologies and create more business opportunities.
Ta Ya is the only cable manufacturer in Taiwan to commit to the development of submarine cables. The completed 33kV optical fiber composite mid-voltage cable (OPMC) falls under the category of “fixed submarine cable”, which is already protected and fixed when laid underwater. In contrast, “submarine dynamic cable” is used to connect various offshore operating platforms (i.e. wave power generation, tidal power station, offshore wind farm, floating PV and so forth) to existing fixed submarine cables. As such, submarine dynamic cables are constantly subjected to harsh tests of crashing waves, stress from platform movement and etc.
Ta Ya has independent possession of relevant IP knowledge for submarine dynamic cable, including submarine communications cable construction, construction and deployment of models, wind, wave and ocean current data, seabed soil environment parameters, fatigue analysis, water seal tests and so forth required for the manufacturing, testing, and verification of cables. Not only that, Ta Ya has also worked with ITRI for the integration of cables and system interface to establish the analytical techniques for dynamic cable simulations to simulate the dynamic behavior of cable under water.
The submarine dynamic cable and its testing platform were put to test at Badouzi Harbor at Keelung on October 22, 2016. After two months of exposure to the harsh environments and the northeast monsoon at sea, the company received good news on the test – ITRI confirmed the deployment to be successful, with normal transmission of signals from both the dynamic cable and optical fiber circuit. The outcome of the test has proven that Ta Ya successfully overcome the challenges of seascape dynamics and will no doubt help to accelerate the development of relevant wave power technologies in Taiwan, thereby offering yet another option for renewable energy for Taiwan.
