Paper Number: SUT-SCADA-10-05
... s concept focusing on utilisation of highly efficient capacitors (see Figure 6). Once again, future subsea systems will require more electrical sensors and hence an extended number of connection points. Considering the mixed experience from the early 1990s, development of a three-stab inductive...

... to reduce pressure without directly bypassing the barrier valves. However, typically alternative paths to the surface are not available for subsea systems, and so the bypass valves become the only answer to the problem. Opinion is divided on this issue. One school of thought argues that the bypass valves...
