Arrangement in a pipeline transportation system

Apparatus for transmitting a fluid selected from gas, oil or a mixture of gas and oil and electric energy between spaced apart locations comprising:

• a) at least one pipe made of a strong, electrically conductive material for transmitting said fluid, said pipe being provided with at least one outer layer of a corrosion resisting material;
• b) a plurality of high voltage electrical energy transmitting elements arranged along said pipe and adapted to transmit and electrical energy at a voltage level of at least 12 kilovolts between said spaced apart locations said elements being in close proximity to an outer surface of the pipe so as to enable heat arising from a loss of electrical energy in said elements to be transferred from said elements to the fluid in said pipe;
• and
• c) regulating means operatively connected to said spaced apart locations for regulating electrical energy from a source passing through said elements and thereby regulating the heat passing to the fluid in the pipe.
