Abstract
Recently, researches on all-electric subsea system have been in progress. This paper describes a subsea tree using a lot of electrical signal and subsea control system. The way of subsea control is classified as all-electric systems or electro hydraulic systems. One of that has more merits in terms of cost, weight, power consumption, etc. because it uses electric signal instead of hydraulic signal. This paper describes the difference of each system’s power consumption and simulation. As the result, if each system applies the same number of sensors, actuators, etc. The power consumption of all-electric system’s load is less than at least 400kWh/day compared to the electro hydraulic system load.
