... 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...

This means the subsea system will have been in operation for the best part of 50 years clearly a major challenge for any industry. The economic implications of failure to adequately support a field are many orders...

The importance of this liquid and the environment in which it operates has greatly affected development and qualification of fluids. Subsea systems have become larger and more complex, but the two major influences over the last...

... and not related to any all- electric subsea system components. Thus, after this period an availability figure of 99.9 percent was produced. Although very promising, it has been decided to further evaluate the system performance by detailed condition monitoring of the subsea system. 3. System Performance...
