At the request of the Institute of Oceanography and Experimental Geophysics of Trieste (OGS), Officine TL Compositi has provided for the construction of the 7.5 meter long rudder, which can be dismantled into 4 pieces, necessary for the connection between the trolley and the towing vehicle.
The steering bell in composite material, the instrument fixing system and the instrument support cradles between the front and rear carriages, in addition to the connection system between them, were also made. All components were made of composite material.
The structure is therefore devoid of metal parts - with the exception of the coupling system to the towing vehicle - in order to eliminate any distortions of the magnetic field created by the instrument during use.
