Abstract: The composition of subsea multiplexed electrohydraulic control system and the working theory of umbilical ESD
vent down in deepwater oil and gas field are introduced. The model is established by AMESim software，with parameters based
on a south China sea oilfield. By simulating the ESD vent down with 4 different tubing size，we get the curves of vent flow
rates，volumes and pressures of subsea accumulator. The proper tubing size was chose based on the simulation results. The
difference is less than 5%compared to the foreign simulation results. The result can provide reference for subsea control system
designing and umbilical selecting.

Key words: ESD vent down, umbilical, simulation, hydraulic tubing size, selection
