Paper presented at the Offshore Technology Conference, May 2–5, 2022
Paper Number: OTC-31933-MS
... 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...
