On line monitoring of the power control and engineering parameters systems of the NEMO Phase-2 tower

The NEMO Collaboration is presently carrying out an intense activity on “NEMO Phase-2” project for the realization of an underwater infrastructure on the deep-sea site of Capo Passero including a fully instrumented 16 storey tower. In this paper the design of the electrical power control system and of a system for the monitoring of some engineering parameters, useful to study the dynamical behavior of the structure, are presented. The proposed architecture is strongly modular and flexible. The entire architecture is described with a special focus on the electrical parameters monitoring, protection system and on the sensors fusion algorithm implemented to deduce the attitude through Micro Electro-Mechanical Systems (MEMS) accelerometers and magnetometer sensors.
