Subsea electrical power system and communication design parameters
The following main parameters need to be determined by means of a system power demand analysis for subsea electrical power system and communication design:
- Voltage at subsea electronic module (SEM) for maximum and minimum SEM power loads;
- Voltages at each SEM at maximum and minimum numbers of subsea control modules (SCMs) on the subsea electrical distribution line;
- Voltages at SEM at minimum and maximum designed umbilical lengths;
- Voltages at SEM at cable parameters for dry and wet umbilical insulation;
- Minimum and maximum subsea power requirements;
- Maximum current load;
- Topsides electrical power unit power factor versus SCM voltage.
A communication analysis is to be conducted to determine the minimum specifications of SCM and master control station (MCS) modems:
- Modem transmit level;
- Modem receive sensitivity;
- Modem source/load impedance.
