Method and a system for controlling the temperature of a fluid in an unbonded flexible pipe

A method for processing, handling or storing a fluid via a floating unit, at least one unbonded flexible pipe for transporting said fluid to the floating unit, and an electric heating system connected to an electric power source, said unbonded flexible pipe comprising a first end terminated in an end-fitting, which is connected to a connector on the floating unit, and a second end connected to a source for fluid, and the first end extending from the end-fitting up to 1500 m towards the second end, the method comprising:

• the temperature of the fluid in at least a part of the first end of the flexible pipe being measured;
• the measured temperature being used as a parameter for partly or fully controlling the electric power input from the electric power source to the heating system;
• and
• the electric power input to the heating system being controlled according to the measured temperature parameter such that the fluid in the first end of the flexible pipe has a temperature substantially corresponding to a predetermined temperature.
