Design and optimization of buoy mooring with single-point cable for seafloor observatories

For long-term mooring buoy observatories in the deep sea far from coasts, we design hybrid system, named Mooring Buoys Observation System with Benthic Electro-optical-mechanical Cable (MBOSBC). The Electro Optical Mechanical (EOM) cable connects surface buoy, and benthic observation node, as transmission link of information power. Different traditional mooring, needs to accomplish energy data between seabed surface. EOM is utilized for it crucial ensure effective work system / transmission. plays role tether MBOSBC. Since has experience higher loads under most environmental conditions long terms. It often happened that, not broken, but power supply core wire signal have broken or failed, while subjected wind, wave current load. This puts forward requirements bearing load style cable. paper gives idea this provide criteria single point We compare dynamics properties line type different external load, optimized. Finally, dynamic during deployment process discussed.
