A life-cycle assessment was performed...

... 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...

Traditionally, to control process valves with safety...

... production trees, manifolds, and a boosting station, together with a subsea distribution and control system. Based on this architecture, an alternative field concept optimized for partial electric actuation resulted in very competitive commercial scenarios in addition to operational benefits and increased...

... The electric system concepts were discussed with the Operator, rapidly resulting in a development contract for an electric choke actuator system for the Statfjord Satellites. The prototype system was installed in December 2001, after only 11 months of development. The prototype system consisted...

... gained during the development of a subsea valve actuator, this paper highlights the importance of the digital twin to speed up the engineering and qualification of an innovative mechatronic system, reducing not only the time to market, but also increasing quality and allowing a fast reaction...

... 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...

... The use of Shared-Actuation Control (SAC) in subsea manifolds has been one of the most disruptive technologies applied in subsea production systems for the last 20 years. In [ 1 ], a comprehensive review of the efforts spent by oil & gas industry along the years, to develop SAC in subsea...

... Abstract This paper presents the development and qualification of a novel Subsea Electric Actuator, especially designed for rotary small-bore valves. One of the main challenges was to design an electric actuator which is as compact as the existing hydraulic actuators, but able to provide a fail...

... and thus not suited for fully remote operations. In 2017, Equinor, Baker Hughes and TECHNI formed a Joint Industry Project (JIP) to develop a new electric actuator control system. The actuator system is designed for fail-safe, critical operations offshore and is subject to stringent safety design...
