... subsea electric actuator technology enables a sustainable energy transition combining the ability to move high forces while being cost effective. For CO 2 storage, it enables an all-electric subsea tree, comparable in price to a traditional hydraulic tree, but without demanding expensive umbilicals...

... Abstract In 2001, the world's first subsea electric choke actuators were installed on live wells in Statfjord Satellite Field in the North Sea. This paper explains the business case for the retrofit solution and highlights the experiences from the operation of the system. Originally, due...

... actuator Eliminates the need for subsea accumulators for control fluid. Eliminates the need for any sea-chests Makes it possible to have all actuators individually retrievable and interchangeable. It also avoids pressurized control fluids and the associated hazards connected with them...

... to now, digital twins were barely implemented to their full potential throughout the design, integration, and operation phases of production and processing equipment. Based on the experiences gained during the development of a subsea valve actuator, this paper highlights the importance of the digital...

... Abstract Electric actuation technology represents the future of subsea production systems. So far there are no standardized generic requirements documented for electrical actuators. A recent Joint Operator Specification attempted to address this lack of information, but it provided only a few...

... was unable to rotate its orientation key to the desired position. Several attempts were unsuccessful. Mechanical damage occurred in the compensation mechanism of RVC electric actuators, with seawater entering in the canisters of actuators. In view of the found flaws, the field test was aborted...

... The directional control valve is evaluated in Table 3 , because it is important for the actuation of the hydraulic actuator. Abstract A detailed knowledge about the health status of the installed assets is the key for continuous production without unexpected events and downtime, which...

... and valves, risk of fluid contamination, downtime due to regular flushing procedures, not easy to retrieve subsea, additional weight and space required by the HPU, etc. The main disadvantage of the available electric actuators is that they are not designed for such low torque levels. They normally offer...

...Introduction Electric actuators for wellhead and production trees An Electric Actuator (EA) system has a simpler overall design than a hydraulic actuator system ( Fig. 3 ) and has no requirement for complex HPU and associated size, weight, and cost. There is also no high-pressure hydraulic...

... debottlenecking that enabled the production of additional 2,000 bpd by routing selected fields to dedicated subsea pumps, instead of commingling low- and high-pressure systems into same inlet pressure pumps. This was enabled by installation of an electrical actuator that automated control of a formally manual...

...Abstract Abstract Equinor & Total are developing an All-Electric Subsea (AES) to replace existing electrohydraulic systems for a standardized water depth independent VXT system. This system will fit the "Subsea Factory" development by Equinor where electric actuation of chokes, manifold...

...Abstract Abstract Valves and actuators are key building blocks to realize subsea processing plants. Both isolation and control valves are key elements for operating processes such as water treatment and injection, boosting and separation. In order to increase the performances and to eliminate...
