Abstract: There is presented an arrangement for cooling components of a subsea electric system. The arrangement comprises a tank filled with a dielectric fluid. The arrangement comprises at least one electric component located in the tank. The arrangement comprises a first heat exchanger located outside the tank and in fluid contact with the tank, and during operation arranged to be in thermal contact with sea water. The arrangement comprises a pump arranged to force a flow of the dielectric fluid through the first heat exchanger. The arrangement is configured such that during operation the dielectric fluid receives heat from the at least one electric component, flows from the tank into the first heat exchanger, flows through the first heat exchanger to transfer heat to the sea water, and flows back from the first heat exchanger into the tank through the pump. The flow of the dielectric fluid in the tank and around the at least one electric component is by natural convection.
