Abstract: An arrangement for an overvoltage protection of a subsea electrical apparatus and a method for operating it. The arrangement includes a tank submersible below a water surface level, an electrical apparatus accommodated in the tank, and a surge arrester arrangement accommodated in the tank and coupled to a power supply of the electrical apparatus in the tank for providing the overvoltage protection of the electrical apparatus. The arrangement further includes a controllable grounding switch for connecting the surge arrester arrangement to a ground point in response to a control of the grounding switch to a closed state and for disconnecting the surge arrester arrangement from the ground point in response to a control of the grounding switch to an open state.

Abstract: A heat exchanging arrangement for a subsea electronic system, the heat exchanging arrangement including: at least one pipe having an external surface; and at least one heat exchanging element arranged inside the at least one pipe and defining at least one internal passage for conducting a dielectric fluid through the at least one pipe; wherein the at least one heat exchanging element is arranged to press laterally outwards against an internal surface of the at least one pipe to establish a heat transfer bond between the at least one heat exchanging element and the at least one pipe. A subsea electronic system including the heat exchanging arrangement is also provided.
