... 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...

... 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...
