STABLE SUBSEA ELECTRIC POWER TRANSMISSION TO RUN SUBSEA HIGH SPEED MOTORS |
摘要 |
The invention provides a subsea pressure boosting system feasible for operation at subsea step out lengths above 40 km and by control merely from a dry topside or onshore location. The system is distinctive in that it comprises: . at least one subsea power step out cable (5), arranged from a near end at a dry location onshore or topsides to one or more subsea loads such as subsea pumps or subsea compressors (M1-M4) at a far end, at the near end at least one source for electric power is connected (1) and the cable is dimensioned for operation at a frequency different from the operation frequency of the connected subsea loads in order to handle the Ferranti effect and electric losses, and . at least one passive electric frequency transformer (G+M), operatively connected between the subsea step out cable far end and the subsea loads, said transformer is located in a pressure vessel and transforms the operation frequency of the subsea step out cable to a frequency feasible for operation of the connected loads. |
