Abstract
The objective of this work is to analyze the dynamic performance of a Subsea Hydraulic Actuator connected to a Hydraulic Power Unit (HPU) which constitutes a Hydraulic Positioning System using Speed Controlled Pump. This system is designed to operate on a Wet Christmas Tree (WCT) installed in a depth of 3.300 meters. A detailed mathematical model was developed representing the system dynamic and static behavior. In this way, the results obtained through simulation are presented, demonstrating the critical points and advantages of using the selected layout. The evaluated parameters are the pressures in the hydraulic cylinder chambers, valve operating time response, positioning capacity of the actuation system, the friction forces acting on the gate valve and the system energy consumption.
