...5Abstract Is the oil and gas offshore industry ready for all-electric subsea fields? A lot of work has been done on the development side towards closing the gap be- tween traditional subsea production equipment operated by hydraulic control systems and systems that are operated all-electric...

... efficiency and availability. Control systems are a key element in addressing this challenge. The next generation of control systems must provide superior availability, lower lifecycle costs and superior performance. Other industries faced with similar increases in complexity and the demand for very high...
