1. An AC transmission system for a power transmission to an offshore plant, the AC transmission system comprising:
an onshore power station which is configured to transmit an electric power;
an offshore plant which is configured to receive the electric power;
a first subsea cable which connects the onshore power station to the offshore plant; and
at least one pipeline which comprises an electrical heating system, the electrical heating system of the at least one pipeline being connected to the offshore plant via a second subsea cable and being connected to the onshore power station through each of the first subsea cable and the second subsea cable via the offshore plant.
